Description

While the functionality to display maps in 3D is freely available as such, we currently only have commercial terrain data available and therefore welcome contributions so that we can later offer this to all users, e.g. in combination with our new high-resolution vector map.

With a little research and the right tools, you should be able to create webp terrain-rgb tiles that we can then put on our CDN.

Contributor guide

Research direction
Research freely available elevation data sources (e.g., Copernicus DEM, SRTM) and use tools like GDAL to generate terrain rgb tiles in WebP format for CDN deployment.
