Possibility to draw lines and points with specific elevation/altitude
New Feature
We need a way to draw lines on 3d maps that have specific elevation/altitude. Currently, it seems that every path is only defined by lat/long and is always glued to the terrain.
This is what we want to achieve:
Why
The value is that now paths, points, and possibility annotations wouldn't be bound to the terrain anymore.
Not sure if there's a workaround to make this possible with the current beta sdk or if there's a plan to support this soon!
Thanks!
We have the same need for our application - showing trajectories of flights. Are there any updates for implementing this feature or potential workarounds?
Same need here - showing trajectories of flights. Any news on this feature?
Same need here. We at SITA also want to display trajectories that have different altitudes. Could you please let us know when this feature will be implemented? Thank you
Any update on if this is a feature in the works, or if there are no plans for such a feature?
Just peeking around. Some of you guys my find this usful: https://deck.gl/examples/mapbox/
@entioentio both great examples but I think what we need is LineString to support altitude. Height doesn't work well for flight paths and rendering webgl doesn't seem like the right solution for populating the map as a flight occurs.
The renderings do look great though! 👏
Thanks for your interest in this feature, and I hope you can help to clarify the requirements. For now, the way to achieve this is with a Metal (iOS) / OpenGL (Android) powered Custom layer.
An example from our internal test code (color encodes distance to ground)...

Custom layer code here, samples the elevation (ground elevation) for all the points along the route and elevates bottom of the wall and and calculates the top.

@codeversed could you please explain the issue in some more details, to avoid missunderstanding?
@txaiwieser @richardpineo @bambubr @amiratsita
I'd like to verify if the altitude information height is always relative to sea level—or does it require combining (ground level offset used for landing?
@astojilj thank you for the update. Is the sample code supposed to be behind a link somewhere? The result looks good enough, can the line be updated live? Example: following a plane flight live.
