Where do you get the terrain elevation data? What resolution is it? I've been looking for good elevation data for another project.

- tppiotrowski 5y agoNextzen has freely available DEM tile data to zoom level 15, so about 5 meters/pixel. You need a free API key [1] Mapbox has paid DEM data to zoom level 20, but I think it's just zoom level 15 scaled up (but the data is cleaner and more recent) [2] Nextzen also open-sourced their elevation tile generator, but I haven't tried to generate my own tiles [3] [1] https://www.nextzen.org/#terrain-tiles https://www.nextzen.org/#terrain-tiles [2] https://docs.mapbox.com/help/troubleshooting/access-elevation-data/ https://docs.mapbox.com/help/troubleshooting/access-elevatio...
