Feature Request: Enhance height diagram indicator with information about marked distance/elevation gain

[tstreibl]

It's already possible to nicely show the height diagram of a route and to select a region in the height diagram between a start/end marker (the selected region is used to automatically zoom into the map). During selection the actual data of the end marker is displayed (height and the distance from route start to the end marker) but the indicator does not use the additional information from the start marker.

Feature Request: would it be possible to additionally display the distance between start/end markers and the accumulated elevation gain between start/end markers? The height diagram of google earth would be a good example for what i mean.

Benefit: on a bike trip, especially through the mountains, you often try to estimate what distance you can travel easily in a day or a certain time. Clearly you want to take the accumulated height into account. For example when you have to go over several passes and elevation accumulates to 1600m height you want to travel only 80 km, whereas on plain terrain you easily could go 120 km. By marking the start/end point in the heigh diagram you could easily detect where on your route (end marker) you reach your personal heigth/distance limits and if by chance a good accomodation is nearby. On a hilly landscape it's often surprising how all the many ascents accumulate in the end. Certainly you can do those calculation by hand as well, but it's tedious.

Thanks for moving the suggestion to a separate issue.

While the elevation graph is provided by https://github.com/nrenner/leaflet.heightgraph, I guess we can track it here too and think a bit outside of it's "box".

For example, where to display statistics about the selected route segment, e.g. elevation gain, distance, travel time?

• One way would be to add a separate textbox to the elevation graph. Only the elevation graph would reflect the selection.
• We could also try to reuse the status bar for displaying statistics of the selection instead. This way the elevation graph would function as a general tool to select / filter parts of a route (*), and also the route and analysis sidebars could react to that, a potential segment list sidebar (see Split multi-day bike trip #430) could offer a button "Copy selection to new route" etc.

(*) Nice to have in this case: mark selection visually on track too, add close/unselect button, allow extending/shrinking/moving the selection with the mouse in the elevation graph, ...

Those are great ideas! And many thanks for this great projekt and all the people making it happen!

I would like to add a point here (coming from the multi-day-split improvement issue/suggestions). It would be great to have cumulative statistics for climb... I am planning a multi-day road route and need to take both distance and climb into account for daily segments. Would it be possible to add (either in the heightgraph, or in the tooltip when hovering over the track (currently shows height and grade)) the cumulative climb up to that point? The distance being shown with points every 5km is great, but its hard to estimate cumulative climbing after X Km from the heightgraph.

This is also an invaluable feature for multi-day MTB trips (trans-alp and the like) so you can plan your daily segments better.

When the cumulative statistics are added to the heightgraph, it would be helpful if the auto-zoom feature could be deaktivated with a check box. Than the heigthgraph could be used as a measuring tool to check the multi-day stops along the road. I'm already completely happy that named waypoints are possible. So I can use waypoints like "day 1", "day 2", ... to plan my multi-day stops.

Any chance to see some progress here? You could copy this feature e.g. from Komoot or Google Earth. It's just one additional Number to display...

Getting somehow the integrated ascending height along the road would be really helpful (as well as seeing local height at cursor location).
