It has been provided -as an `LGPL`_-licensed stand-alone software library to allow other softwares -that handle LAS data to read and write LASzip-compressed data. The BSD-licensed -`libLAS`_ and the LGPL-licensed `LASlib`_ can take advantage of LASzip to read -and write compressed data. - -LASzip was originally released as an `LGPL`_-licensed library, but in January -2022, it was relicensed as `Apache Public License 2.0 -`__ by `Rapidlasso GmbH -`__. For those wishing for validation of this licensing -change, a notarized document to that effect is available by contacting -Howard Butler at howard@hobu.co or Rapidlasso, GmbH at info@rapidlasso.de. - -LASzip is completely lossless. It compresses bulky LAS files into compact LAZ -files that are only 7-20 percent of the original size, accurately preserving -every single bit. For example, compressing and decompressing the LAS file -lidar.las with `laszip.exe`_ (command-line only `laszip-cli.exe`_) as shown below results in lidar_copy.las that -is bit-identical to lidar.las. However, the small size of lidar.laz makes it -much easier to store, copy, transmit, or archive large amounts of LIDAR. - -* laszip -i lidar.las -o lidar.laz -* laszip -i lidar.laz -o lidar_copy.las - -LASzip compression can be many times smaller and many times faster than -generic compressors like `bz2`_, `gzip`_, and `rar`_ because it knows what -the different bytes in a LAS file represent. Another advantage of LASzip -is that it allows you to treat compressed LAZ files just like standard LAS -files. You can load them directly from compressed form into your application -without needing to decompress them onto disk first. The availability of the -`LASzip`_ DLL and two APIs, `libLAS`_ and `LASlib`_, with LASzip capability -makes it easy to add native LAZ support to your own software package. - -Software with native LAZ support ------------------------------------------------------------------------------- - -* Fugroviewer (2.0 and up) by `Fugro `_ -* QT Modeler (7.1.6 and up) by `Applied Imagery `_ -* ERDAS IMAGINE (14.1 and up) by `Hexagon Geospatial `_ -* Global Mapper (13.1 and up) by `Blue Marble Geo `_ -* Trimble RealWorks (8.1 and up) by `Trimble Navigation Limited `_ -* ENVI LiDAR (5.1 and up) by `Exelis VIS `_ -* FME (2012 and up) by `Safe Software `_ -* TopoDOT by `Certainty3D `_ -* Pointools by `Bentley Systems `_ -* Pix4uav by `Pix4D `_ -* CloudCompare by `Daniel Girardeau-Montaut `_ -* SURE by `nframes `_ -* Pointfuse by `Arithmetica `_ -* LAStools by `rapidlasso - fast tools to catch reality `_ -* plas.io 3D Web Viewer by `Hobu Inc. `_ -* RiProcess by `RIEGL LMS GmbH `_ -* CloudPro by `Leica Geosystems AG `_ -* Optech LMS (3.0 and up) by `Teledyne Optech `_ -* Leica LIDAR Survey Studio LSS (2.2 and up) by `Leica Geosystems AG `_ -* FUSION (3.40 and up) by `Bob McGaughey of the USDA `_ -* ZEB1 by `3D Laser Mapping `_ -* OCAD (11.4.0 and up) by `OCAD Inc. `_ -* Gexcel R3 by `Gexcel `_ -* Voyager (1.3 and up) by `Voyager GIS `_ -* LIDAR Analyst (5.2 or 6.0 and up) by `TEXTRON Systems `_ -* TerraScan, TerraMatch, TerraPhoto, and TerraSlave (015.xxx and up) by `Terrasolid `_ -* Carlson (2016 and up) by `Carlson Software `_ -* Remote Sensing Software by `Joanneum Research Forschungsgesellschaft mbH `_ -* LiMON Viewer by `Dephos Software `_ -* Scanopy by `imagination `_ -* WinGeoTransform by `KLT Assoc `_ -* BayesStripAlign by `BayesMap Solutions, LLC `_ -* Point Cloud Technology by `Point Cloud Technology, GmbH `_ -* Scalypso by `Ingenieurbuero Dr.-Ing.

LASzip is completely lossless: It compresses bulky LAS files into compact LAZ files that are only 7-20% of the original size, while accurately preserving every single bit. Likewise, LAZ files can be decompressed into a bitwise identical LAS file. LASzip allows compressed LAZ files to be treated like standard LAS files. They can be loaded directly from the compressed form into an application without first decompressing them to a disk. @@ -9,6 +9,9 @@ This is the repository of the open source LAZ compressor under the

We starts a new context when the delta overflows a 32 bit integer. For that it difference codes the 32 higher bits of the current GPS time and the current context and stores the lower 32 bits raw. Otherwise it switches to the specified context (where the delta will not overflows a 32 bit integer) and recurses. The current deltas stored with each context are updated to the actual delta when they were outside the predictable range more than 3 consecutive times (i.e. bigger than 500 times the current delta, smaller than -10 times the current delta, or zero). Compression of RGB layer ------------------------------- +------------------------ We compress the RGB values the same way it was done in the old LASzip coder. LAS uses unsigned 16 bit integers for the R, G, and B channel. Some files—incorrectly—populate only the lower 8 bits so that the upper 8 bits are zero. Other files correctly multiply 8-bit colors with 256 so that the lower 8 bits are zero. The LASzip compressor therefore compresses the upper and lower byte of each channel separately. First it entropy codes (a) 6 bits that specify which of the six bytes have changed in comparison to the previous point (from the same scanner channel) and (b) one bit that specifies whether those changes are the same in all three channels (i.e. grey colors) as one symbol between 0 and 127. For all bytes that have changed it then entropy codes the difference to the respective previous byte (of the point from the same scanner channel) modulo 256. If the 7 bit symbol indicates that the changes are identical in all three channels only the R channel is compressed. Otherwise the channels are encoded in the order R, G, and B. Differences encoded in earlier channels are used to predict differences in later channels as there tends to be a correlation in the intensity across channels. For example, if there was a byte difference in the low byte of the R channel that difference is added to low byte of the G channel which - clamped to a 0 to 255 range - becomes the value to which the difference of the current low byte is computed. Compression of NIR layer ------------------------------- +------------------------ We compress the NIR value using the same technique as done for the RGB values. First it entropy codes 2 bits that specify which bytes have changed as one symbol. For all bytes that have changed it then entropy codes the difference to the respective previous byte (of the point from the same scanner channel) modulo 256. Compression of WavePacket layer ------------------------------- +------------------------------- We compress the WavePackets the same way it was done in the old LASzip coder. They only occur in point types 9 and 10. So far there has been very little real-world demand for compressing LAS files containing waveform data simply due to a lack of data stored in this format (i.e. there is no a dedicated format for full waveform LiDAR called 'PulseWaves'). LASzip simply entropy codes the wave packet descriptor index, an unsigned byte that is zero if a point has no waveform and indexes the variable length record describing the format of the waveform otherwise. To compress the bytes offset to waveform data it entropy encodes one of 4 possible cases: 1) same as last offset 2) use last offset plus last packet size @@ -234,5 +234,5 @@ We compress the WavePackets the same way it was done in the old LASzip coder.

Only waveform packet size in bytes is an integer number.

A LAS point has “Extra Bytes†when the LAS header specifies a point size larger than required by the respective point type. Each “Extra Byte†is entropy encoded with its own context as the difference to the “Extra Byte†from the previous point (from the same scanner channel) modulo 256. Treating them as individual bytes is the best that the LASzip compressor can do as there is not always a description what these “Extra Bytes†may mean. Six “extra bytesâ€, for example, could be a single-precision float storing the echo width followed by an unsigned short storing the normalized reflectivity. Or it could be an unsigned short storing a tile index followed by an unsigned integer storing the original index of the point. diff --git a/src/vendor/LASzip-3.5.0/dist.vcxproj

LASzip is completely lossless: it compresses bulky LAS files into compact LAZ files that are only 7-20% of the original size, while accurately preserving every single bit. Likewise, LAZ files can be decompressed into a bitwise identical LAS file. LASzip allows compressed LAZ files to be treated like standard LAS files. They can be loaded directly from the compressed form into an application without first decompressing them to a disk. + +LASzip is included in our full download package and available as source code to be compiled in Windows, Linux or MacOS environments. LASzip is provided as an Apache 2.0-licensed standalone software library. + + +Binary Download +.............................................................................. + +`download page `_ + + +Source +.............................................................................. + +`github sources `_ + + +Specification +.............................................................................. + +`LAZ Specification 1.4 `_ + + +Example +.............................................................................. + +Compressing & decompressing the LAS file lidar.las with laszip.exe as shown below, results in lidar_copy.las that are bit-identical to lidar.las.

In November 2011, Martin presented his innovation at ELMF in Salzburg, Austria (`paper `_ and `video `_). LASzip, winner of the “2012 Geospatial World Forum Technology Innovation Award in LiDAR Processing†and runner-up for the “most innovative product at INTERGEO 2012â€, quickly gained popularity and over the years became the de-facto standard for compressed LiDAR. + +Beyond being a gifted software developer, Martin was keenly aware of our impact on the world. He wasn’t just about technology, but also about technology’s potential to improve our planet and the human condition. Martin was talking about reducing the carbon footprint of computing before almost anyone else. The carbon footprint he saved by giving away LASzip will have a lasting impact. Martin made outstanding contributions to the LiDAR community, and he was a source of inspiration to many. This will not be forgotten. Martin `passed away `_ on September 7, 2021. May he rest in peace. diff --git a/src/vendor/LASzip-3.4.4/example/CMakeLists.txt b/src/vendor/LASzip-3.5.0/example/CMakeLists.txt similarity index 98% rename from src/vendor/LASzip-3.4.4/example/CMakeLists.txt rename to src/vendor/LASzip-3.5.0/example/CMakeLists.txt index 54903be..9a0b53e 100644 --- a/src/vendor/LASzip-3.4.4/example/CMakeLists.txt +++ b/src/vendor/LASzip-3.5.0/example/CMakeLists.txt @@ -25,7 +25,7 @@ set(LASZIP_UTILITIES if(WIN32) if(NOT BUILD_STATIC) - add_definitions("-DLASZIP_DLL_IMPORT=1") + add_definitions("-DLASZIP_DLL_IMPORTS=1") endif() endif() diff --git a/src/vendor/LASzip-3.4.4/example/laszip-config.in b/src/vendor/LASzip-3.5.0/example/laszip-config.in similarity index 100% rename from src/vendor/LASzip-3.4.4/example/laszip-config.in rename to src/vendor/LASzip-3.5.0/example/laszip-config.in diff --git a/src/vendor/LASzip-3.4.4/example/laszip.pc.in b/src/vendor/LASzip-3.5.0/example/laszip.pc.in similarity index 100% rename from src/vendor/LASzip-3.4.4/example/laszip.pc.in rename to src/vendor/LASzip-3.5.0/example/laszip.pc.in diff --git a/src/vendor/LASzip-3.4.4/example/laszipdllexample.cpp b/src/vendor/LASzip-3.5.0/example/laszipdllexample.cpp similarity index 100% rename from src/vendor/LASzip-3.4.4/example/laszipdllexample.cpp rename to src/vendor/LASzip-3.5.0/example/laszipdllexample.cpp diff --git a/src/vendor/LASzip-3.4.4/example/laszippertest.cpp b/src/vendor/LASzip-3.5.0/example/laszippertest.cpp similarity index 100% rename from src/vendor/LASzip-3.4.4/example/laszippertest.cpp rename to src/vendor/LASzip-3.5.0/example/laszippertest.cpp diff --git a/src/vendor/LASzip-3.5.0/include/laszip/laszip_api_version.h b/src/vendor/LASzip-3.5.0/include/laszip/laszip_api_version.h new file mode 100644 index 0000000..954d5bb --- /dev/null +++ b/src/vendor/LASzip-3.5.0/include/laszip/laszip_api_version.h @@ -0,0 +1,48 @@ +/* +=============================================================================== + + FILE: laszip_api_version.h + + CONTENTS: + + Version information for LASzip API interface + + NOTE: + laszip_api_version.h will be generated dynamic out of laszip_api_version.h.in by cmake build. + The file laszip_api_version.h is static in the repository to allow also a *.sln build. + + PROGRAMMERS: + + info@rapidlasso.de - https://rapidlasso.de + + COPYRIGHT: + + (c) 2007-2022, rapidlasso GmbH - fast tools to catch reality + + This is free software; you can redistribute and/or modify it under the + terms of the Apache Public License 2.0 published by the Apache Software + Foundation.

LiDAR compression* + +Open-source compression library for compressing LAS to LAZ. +LASzip is completely lossless: It compresses bulky LAS files into compact LAZ files that are only 7-20% of the original size, while accurately preserving every single bit. Likewise, LAZ files can be decompressed into a bitwise identical LAS file. LASzip allows compressed LAZ files to be treated like standard LAS files. They can be loaded directly from the compressed form into an application without first decompressing them to a disk. + +This is the repository of the open source LAZ compressor under the terms of the Apache Public License 2.0. + +For the full LASlib and LAStools repository include the popular open source tools las2las, las2txt, txt2las please see https://github.com/LAStools/LAStools + +# Specification + +LAZ Specification 1.4 - Revision R1 available at https://rapidlasso.de/laszip/ + +# Installation + +Binary downloads for Windows and Linux are available at + https://rapidlasso.de/downloads + +# Compilation + +Just go to the root directory and run + cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt + cmake --build . + +# Links + +* official website: https://rapidlasso.de +* user group: http://groups.google.com/group/lastools + +# License + +Apache Public License 2.0. +See `COPYING` file for the license text. + +# Summary +Your feedback is highly appreciated.

This includes feedback from our `"Open Call for Input" `_ from early 2014 as well as ideas from out initial proposal for a joint `LAS 1.4 compressor with ESRI `_ that was presented in form of a widely circulated and loudly applauded `April Fools' Day prank `_ after months of direct communication with ESRI had failed to produce any useful progress. + +We should point out that the current `LASzip compressor `_ can already handle (most) LAS 1.4 files via the `"LAS 1.4 compatibility mode" `_ that was sponsored in part by NOAA, Quantum Spatial, and Trimble. However, LAS 1.4 files are likely to stay with us for a long long time. The "native extension" of LASzip seeks to exploit the "natural break" in the lineage of the LAS specification to add entirely new features to the compressor that allow better exploitation of LAS files in the cloud or on Web portals as originally planned and suggested in the `joint proposal `_. + +In the past ESRI has claimed to have identified very particular needs for processing LiDAR in the cloud that have warranted the development of their competing closed standard also know as the `"LAZ clone" `_. The resulting format fragmentation has `upset `_ the geospatial community and led to an `Open Letter `_ by OSGeo that has asked ESRI to change their course and work with the LiDAR users to avoid a format war. In parallel to the `on-going mediation `_ under way via the Open Geospatial Consortium (OGC) in form of a new `Point Cloud Domain Working Group `_ we are intending to progress towards a set of useful features for compressed LAS 1.4 content in the open and transparent manner, yet at the speed that the needs of our industry demands. Therefore we invite in particular ESRI to tell us what exactly they want us to include in the "native extension" of `LASzip `_ to the new point types: + +.. + + Dear ESRI, please tell us what features would you like in the native LAS 1.4 extension of LASzip? What exactly are the key differences of your own "optimized LAS" that are currently missing in LASzip? + +.. + +Some of the things that ESRI has added to "optimized LAS" are already part of LASzip and others may already be on our TODO list. So as we wait for ESRI's answer, let's already start fleshing out the feature set that the rest of the community wants to see in the new LASzip: + +Core Features +------------- +**1. Selective Decompression:** + +Often only a subset of all the attributes of a LiDAR return stored in the LAS format are actually needed by an application. Currently all points attributes have to be read and decompressed by an application opening a LAS or a LAZ file. This is the most far reaching new feature of the native LAS 1.4 extension of LASzip: for the new point types, it will allow reading and decompressing only those points attributes that are relevant to the application. A Web-based LiDAR viewer, for example, may only have to download, parse, and decompress the xyz coordinates and the intensities of the point cloud and a cloud-based service for DTM generation will only have to download, parse, and decompress the xyz coordinates and the classification values. + +**2. Variable Chunking:** + +Instead of having each atomic unit of points that are compressed together - a chunk - have the same size of a default 50,000 points the compressor offer the option to let each chunk have a different size. This is in particularly useful when creating point orders that support spatially indexing by rearranging them, for example, into the cells of a quad tree that are laid out along a space-filling curve. Variable chunking allows granular access to only those points of a cell that was selected for loading. + +Optional Features +----------------- + +**3. Tighter Integration of Spatial Indexing (likely)** + +Already supported in the existing LASzip compressor as an optional item this will become a mandatory part of every new LAZ file that is written. Area-of-interest queries are also a form or "selective decompression" and require two things: Knowledge where in the file the points that fall into the interesting area are located (e.g. in the seventeen point intervals [5236312,5236312], [6523634,6634523], ....) and the ability to seek in the compressed file and decompress only those point intervals. The letter has been an integral part of the LASzip compressor since day one as this was one of the core features sponsored by USACE. The first has been added after little by little to LASzip in order not to disrupt anything since the concept (i.e. LASindex and tiny LAX files) was first introduced at ELMF in 2012. The concept needs to be reworked slightly to accommodate files with over 4 billion points. + +**4. Re-writeable Flags and Classification (maybe, definitely via LASlayers of LASlib) ** + +Most of the point attribute of an LAS file will never change --- *at laest* once the LiDAR was published. The xyz coordinates are final once the LiDAR flightlines were aligned, the return counts are fix, the intensities are direct measured, and the original GPS time stamps and the point source IDs should be preserved for posterity. What often does change, however, are the point classifications into "ground", "building", "noise", or "water" points, as well as the flags describing which points are to be "withheld" or which ones are part of the not always desired "overlap". This is the second far reaching new feature of the native LAS 1.4 extension of LASzip: based on mechanisms that have already been field-tested as part of the "LASlayers" effort the new LASzip will support overriding the existing classifications or flags with a new layer of values. + +**4. Attach-able Attributes (maybe, more likely via LASlayers of LASlib) ** + +Some LiDAR processing steps create additional per-point attributes such as RGB colors or NDVI values from a different source, error estimates, or point normals. During the design process of the the native LAS 1.4 extension of LASzip we want to consider to allow adding such attributes later without requiring a complete re-write of all existing points attributes that have not changed. + +**5. Explode-able Files (maybe, more likely via LASlayers of LASlib) ** + +Selective decompression - or more importantly selective download - of large files may in some cases be more feasible to implement for a 3D Web viewer or a LiDAR service portal when the data for selectable attributes is stored for download in separate files. During the design process of the the native LAS 1.4 extension of LASzip we want to accomodate to later add the option to store one compressed LAZ file as a number of compressed files each of which encodes a different set of point attributes. + +**6. Specification Document (`in progress `_) ** + +The LASzip compressor is currently only documented via an open source reference implementation in C++. In order to create LASzip compressors and decompressors in other programming languages it is currently necessary to step through the (reasonably well documented) C++ source code. We hope that funds can be made available that allow us to hire technical writers who can create a proper `specification document `_ that describes the open LASzip compressed LiDAR format. + +Open Forum +---------- +Please join us to continue the already on-going discussion in the `"LAS room" `_ where we will finalize the feature set in an open censensus process. diff --git a/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/design/specification.rst b/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/design/specification.rst new file mode 100644 index 0000000..327d34a --- /dev/null +++ b/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/design/specification.rst @@ -0,0 +1,238 @@ +LASzip for LAS 1.4 (native extension) +===================================== +Specification Document +---------------------- +As before the LASheader and the VLRs are stored uncompressed but the highest bit of the point type field is set (i.e. the compressed point types 128 to 138 correspond to the uncompressed point types 0 to 10). LiDAR points are compressed in completely independent chunks that default to 50,000 points per chunk. Each chunk can be decompressed "on its own" once the start byte is know. For point types 0 to 5 nothing changes and the same compression scheme as before is used. For the new point types 6 to 10 of LAS 1.4 there are two main changes: the chunks are encoded in layers and the chunks can have variable size. + +As before the first point of each chunk is stored raw. The attributes of all following points are broken into several layers. Only the first layer containing the x and y coordinates (and a few pieces of information) is mandatory to read and decompress. The remaining layers containing independently useful attributes such as elevation, intensity, classifications, flags, GPS times, colors, point source ID, user data, scan angles, wavepackets, and extra bytes do not necessarily need be decompressed (or be read from disk). + +Another new (or rather "revived") feature in LASzip compression for the new point types of LAS 1.4 is that it will be possible to continously vary the chunk size. This was in the design of the original LASzip coder but broke whenever the file was streamed due to missing access to the per chunk point counts during a streaming read as those were only stored in the chunk table at the very end of the LAZ file.

All following predictions in all different layers are relative to the previous point from the *same* scanner channel. They first check whether the current point is from the same scanner channel and switch context if not. If no previous point exists for the new scanner channel (because this scanner channel appears the first time in this chunk) then the previous point (from whichever other scanner channel) is used. For the very first point per chunk *that gets compressed* this is that one point that is stored raw at the beginning of every chunk. + +Only if the **number of returns has an other difference** (as indicated by the 7 bits earlier) we use one symbol whose value ranges from 0 to 15 that we then compress with the previous number of returns (from the same scanner channel) as one of sixteen contexts. + +Only if the **return number is different** (as indicated by the 7 bits earlier) we encode in in two possible ways depending on whether the GPS time stamp has changed: + - if the GPS time stamp *has not* changed we use one symbol whose value ranges from 0 to 12 to encode whether we need to add 2, 3, 4 ... 12, 13 or 14 to the previous return number (from the same scanner channel) to get (modulo 16) to the current return number that we then compress using the previous return number (from the same scanner channel) as one of sixteen contexts. + - if the GPS time stamp *has* changed we use one symbol whose value ranges from 0 to 15 to encode the current return number that we then compress with the (already encoded) number of returns as one of sixteen contexts. + +Next we use the number of returns n and the return number r to to derive two numbers between 0 and 15 that are used for switching contexts later: a *return map m* and *a return level l*. + +The *return map m* simply serializes the valid combinations of r and n: for r = 1 and n = 1 it is 0, for r = 1 and n = 2 it is 1, for r = 2 and n = 2 it is 2, for r = 1 and n = 3 it is 3, for r = 2 and n = 3 it is 4, for r = 3 and n = 3 it is 5, for r = 1 and n = 4 it is 6, etc. Unfortunately, some LAS files start numbering r and n at 0, only have return numbers r, or only have number of return of given pulse counts n. We therefore complete the table to also map invalid combinations to be used as a context. Furthermore with up to 15 returns there would be too many different combinations (namely 120).

Its values are single = 3, first = 1, last = 2, and intermediate = 0 and it is computed: + +I32 cpr = (r == 1 ? 2 : 0); // is first ? +cpr += (r >= n ? 1 : 0); // is last ? + +We encode the X and Y coordinates with a second order predictor. We predict the differences dX and dY to the X and Y coordinates of the previous point from the same scanner channel with recently occuring differences. We predicts dX and dY between as the median of the five immediately preceding differences of points from the scanner channel and with the same return map m. The intuition behind this is, for example, that single returns are always from a different laser pulse than the previous point and therefore have a wider spacing in X and/or Y than the middle of three returns. + +Compression of classification layer +----------------------------------- +We compress the classification as a symbol between 0 and 255 using 64 different context. This context is computed as the five lowest bits of the classification of the previous point (from the same scanner channel) multiplied by two plus one when the previous point (from the same scanner channel) was a single return. + +Compression of flags layer +-------------------------- +We compress the classification as a 6 bit number or a symbol between 0 and 63 using 64 different context. The highest bit is the 'edge_of_flight_line' flag. The second higest bit is the 'scan_direction' flag. The lowest four bits are the four classification flags in the order listed in the LAS 1.4 specification. The context is simply the 6 bit number that represented the flags of the previous point (from the same scanner channel). + +Compression of intensity layer +------------------------------ +We compress the intensity with the difference integer compressor using four contexts that is simply the 'cpr' defined earlier. We use one of 8 possible previous intensities as the prediction. Which one is used is decided by the 'cpr' multiplied by two plus one if the GPS time in respect to the previous point (from the same scanner channel) has changed. All eight possible previous intensities are initialized to the intensity of the first point (from the same scanner channel) and updated after the intensity was compressed. + +Compression of scan angle layer +------------------------------- +Only if the **scan angle is different** (as indicated by the 7 bits earlier) we compress it with the difference integer compressor using two contexts that is whether the GPS time stamp of the previous point (from the same scanner channel) has changed (1) or not (0). We use the scan angle of the previous point (from the same scanner channel) as the prediction. + +Compression of user data layer +------------------------------ +We compress the user data layer which is an 8 bit number as a symbol between 0 and 255 using 64 different contexts. The context is simply the user data of the previous point (from the same scanner channel) divided by 4. + +Compression of point source ID layer +------------------------------------ +Only if the **point source ID is different** (as indicated by the 7 bits earlier) we compress + +Compression of GPS time layer +----------------------------- +Only if the **GPS time is different** (as indicated by the 7 bits earlier) we compress it the same way it was done in the old LASzip coder. The GPS times of a single flight line stored in aquisition order are a monotonically increasing sequence of double-precision floating-point numbers where returns of the same pulse have the same GPS time and where subsequent pulses have a more or less constant spacing in time. LASzip treats the double-precision floating-point GPS times as signed 64 bit integers and predicts the deltas between them. We store up to four previously compressed GPS times with corresponding deltas to account for repeated jumps in GPS times that can arise when multiple flight paths are merged with fine spatial granularity. Nothing needs to be encoded when the GPS times are identical. Otherwise we distinguishes several cases that are entropy coded with 515 symbols depending on if the current GPS time is + + + 0–500 : predicted using the current delta times 0 to 500. + + 501–510 : predicted using the current delta times -1 to -10. + + 511 : starting a new context. + + 512–514 : predicted with one of the other three contexts. + +For the first two cases we subsequently difference code the delta prediction and the actual delta. We starts a new context when the delta overflows a 32 bit integer. For that it difference codes the 32 higher bits of the current GPS time and the current context and stores the lower 32 bits raw. Otherwise it switches to the specified context (where the delta will not overflows a 32 bit integer) and recurses. The current deltas stored with each context are updated to the actual delta when they were outside the predictable range more than 3 consecutive times (i.e. bigger than 500 times the current delta, smaller than -10 times the current delta, or zero). + +Compression of RGB layer +------------------------ +We compress the RGB values the same way it was done in the old LASzip coder. LAS uses unsigned 16 bit integers for the R, G, and B +channel. Some files—incorrectly—populate only the lower 8 bits so that the upper 8 bits are zero. Other files correctly multiply 8-bit colors with 256 so that the lower 8 bits are zero. The LASzip compressor therefore compresses the upper and lower byte of each channel separately. First it entropy codes (a) 6 bits that specify which of the six bytes have changed in comparison to the previous point (from the same scanner channel) and (b) one bit that specifies whether those changes are the same in all three channels (i.e. grey colors) as one symbol between 0 and 127. For all bytes that have changed it then entropy codes the difference to the respective previous byte (of the point from the same scanner channel) modulo 256. If the 7 bit symbol indicates that the changes are identical in all three channels only the R channel is compressed. Otherwise the channels are encoded in the order R, G, and B. Differences encoded in earlier channels are used to predict differences in later channels as there tends to be a correlation in the intensity across channels. For example, if there was a byte difference in the low byte of the R channel that difference is added to low byte of the G channel which - clamped to a 0 to 255 range - becomes the value to which the difference of the current low byte is computed. + +Compression of NIR layer +------------------------ +We compress the NIR value using the same technique as done for the RGB values. First it entropy codes 2 bits that specify which bytes have changed as one symbol. For all bytes that have changed it then entropy codes the difference to the respective previous byte (of the point from the same scanner channel) modulo 256. + +Compression of WavePacket layer +------------------------------- +We compress the WavePackets the same way it was done in the old LASzip coder. They only occur in point types 9 and 10. So far there has been very little real-world demand for compressing LAS files containing waveform data simply due to a lack of data stored in this format (i.e. there is no a dedicated format for full waveform LiDAR called 'PulseWaves'). LASzip simply entropy codes the wave packet descriptor index, an unsigned byte that is zero if a point has no waveform and indexes the variable length record describing the format of the waveform otherwise. To compress the bytes offset to waveform data it entropy encodes one of 4 possible cases: + 1) same as last offset + 2) use last offset plus last packet size + 3) difference to last offset is less than 32 bits + 4) difference to last offset is more than 32 bits +In the first two cases no other information is needed. For the other two cases LASzip difference codes the 32 or the 64 bit numbers. The LASzip compressor difference coded all remaining fields. Only waveform packet size in bytes is an integer number. The return point waveform location, x(t), y(t), and z(t) are single-precision floating-point numbers whose 32 bits are treated as if they were a 32-bit integer. + +Compression of "Extra Bytes" layer(s) +------------------------------------- +We compress the "Extra Bytes" the same way it was done in the old LASzip coder but each byte is compressed into its own layer. A LAS point has “Extra Bytes†when the LAS header specifies a point size larger than required by the respective point type. Each “Extra Byte†is entropy encoded with its own context as the difference to the “Extra Byte†from the previous point (from the same scanner channel) modulo 256. Treating them as individual bytes is the best that the LASzip compressor can do as there is not always a description what these “Extra Bytes†may mean. Six “extra bytesâ€, for example, could be a single-precision float storing the echo width followed by an unsigned short storing the normalized reflectivity. Or it could be an unsigned short storing a tile index followed by an unsigned integer storing the original index of the point. diff --git

LASzip is completely lossless: it compresses bulky LAS files into compact LAZ files that are only 7-20% of the original size, while accurately preserving every single bit. Likewise, LAZ files can be decompressed into a bitwise identical LAS file. LASzip allows compressed LAZ files to be treated like standard LAS files. They can be loaded directly from the compressed form into an application without first decompressing them to a disk. + +LASzip is included in our full download package and available as source code to be compiled in Windows, Linux or MacOS environments.

In November 2011, Martin presented his innovation at ELMF in Salzburg, Austria (`paper `_ and `video `_). LASzip, winner of the “2012 Geospatial World Forum Technology Innovation Award in LiDAR Processing†and runner-up for the “most innovative product at INTERGEO 2012â€, quickly gained popularity and over the years became the de-facto standard for compressed LiDAR. + +Beyond being a gifted software developer, Martin was keenly aware of our impact on the world. He wasn’t just about technology, but also about technology’s potential to improve our planet and the human condition. Martin was talking about reducing the carbon footprint of computing before almost anyone else. The carbon footprint he saved by giving away LASzip will have a lasting impact. Martin made outstanding contributions to the LiDAR community, and he was a source of inspiration to many. This will not be forgotten. Martin `passed away `_ on September 7, 2021. May he rest in peace. diff --git a/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/example/CMakeLists.txt b/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/example/CMakeLists.txt new file mode 100644 index 0000000..9a0b53e --- /dev/null +++ b/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/example/CMakeLists.txt @@ -0,0 +1,98 @@ +############################################################################### +# +# tools/CMakeLists.txt controls building of laszip utilities +# +# Copyright (c) 2009 Mateusz Loskot +# +############################################################################### + +include_directories( + . + ../include + ../include/laszip) + + +set(APPS_CPP_DEPENDENCIES + ${LASZIP_LIB_NAME}) + + +set(LASZIPPERTEST laszippertest) + + +set(LASZIP_UTILITIES + ${LASZIPPERTEST} + ) + +if(WIN32) +if(NOT BUILD_STATIC) + add_definitions("-DLASZIP_DLL_IMPORTS=1") +endif() +endif() + + +# TODO: Experimental and requires testing --mloskot +# Generate user-specific settings for Visual Studio project +set(VCPROJ_USER_REMOTE_MACHINE_DEBUG ${MACHINE_NAME}) +set(VCPROJ_USER_ENVIRONMENT_DEBUG "${ENVIRONMENT_PATH}") + +if(MSVC) + foreach(utility ${LASZIP_UTILITIES}) + set(USER_FILE ${utility}.vcproj.$ENV{USERDOMAIN}.$ENV{USERNAME}.user) + set(OUTPUT_PATH ${CMAKE_CURRENT_BINARY_DIR}/${USER_FILE}) + message(STATUS "Generating ${CMAKE_GENERATOR} user-specific settings in ${USER_FILE}") + configure_file(${CMAKE_SOURCE_DIR}/cmake/laszip.vcproj.user.template ${OUTPUT_PATH} @ONLY) + endforeach() +endif() + + +if(LASZIPPERTEST) + add_executable(${LASZIPPERTEST} laszippertest.cpp) + target_link_libraries(${LASZIPPERTEST} ${APPS_CPP_DEPENDENCIES} ) + if (EMSCRIPTEN) + SET_TARGET_PROPERTIES(${LASZIPPERTEST} PROPERTIES SUFFIX .js) + endif() +endif() + + +if(UNIX) + # Autoconf compatibility variables to use the same script source. + set(prefix ${CMAKE_INSTALL_PREFIX}) + set(exec_prefix ${CMAKE_INSTALL_PREFIX}/bin) + set(libdir ${CMAKE_INSTALL_PREFIX}/lib) + + GET_DIRECTORY_PROPERTY(LASZIP_DEFINITIONS DIRECTORY ${laszip_SOURCE_DIR}/ COMPILE_DEFINITIONS) + + set(LASZIP_CONFIG_DEFINITIONS "") + foreach(definition ${LASZIP_DEFINITIONS}) + set(LASZIP_CONFIG_DEFINITIONS "${LASZIP_CONFIG_DEFINITIONS} -D${definition}") + endforeach() + + + configure_file(${CMAKE_CURRENT_SOURCE_DIR}/laszip-config.in + ${CMAKE_CURRENT_BINARY_DIR}/laszip-config @ONLY) + + install(FILES ${CMAKE_CURRENT_BINARY_DIR}/laszip-config + DESTINATION bin/ + PERMISSIONS + OWNER_READ OWNER_EXECUTE GROUP_READ GROUP_EXECUTE WORLD_READ WORLD_EXECUTE) + + #pkgconfig + set(PKGCFG_PREFIX "${CMAKE_INSTALL_PREFIX}") + set(PKGCFG_INC_DIR "${CMAKE_INSTALL_PREFIX}/${LIBLAS_INCLUDE_SUBDIR}") + set(PKGCFG_LIB_DIR "${CMAKE_INSTALL_PREFIX}/${LIBLAS_LIB_SUBDIR}") + set(PKGCFG_REQUIRES "") + set(PKGCFG_VERSION ${VERSION}) + set(PKGCFG_LINK_FLAGS "-llaszip") + set(PKGCFG_COMPILE_FLAGS "$CMAKE_CXX_FLAGS") + configure_file(${CMAKE_CURRENT_SOURCE_DIR}/laszip.pc.in + ${CMAKE_CURRENT_BINARY_DIR}/laszip.pc @ONLY) + + +endif(UNIX) +############################################################################### +# Targets installation + +install(TARGETS ${LASZIP_UTILITIES} + RUNTIME DESTINATION ${LASZIP_BIN_DIR} + LIBRARY DESTINATION ${LASZIP_LIB_DIR} + ARCHIVE DESTINATION ${LASZIP_LIB_DIR}) diff --git a/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/example/laszip-config.in b/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/example/laszip-config.in new file mode 100644 index 0000000..860e370 --- /dev/null +++ b/src/vendor/LASzip-4f39c23907bb92cc583aa95bb2ace2ca4f6efdbe/example/laszip-config.in @@ -0,0 +1,67 @@ +#!/bin/sh +prefix=@prefix@ +exec_prefix=@exec_prefix@ +libdir=@libdir@ + +INCLUDES="-I${prefix}/include " +LIBS="-L$libdir -llaszip" + + + +usage() +{ + cat <&2 +fi + +case $1 in + --libs) + echo $LIBS + ;;
