I need to some calculation with terrain surface, I use cesium but it works slow. Cesium has a method sampleTerrainMostDetailed, it gives me height of given coordinates but it calculates height on client.

sampleTerrainMostDetailed works like this:

  1. create tiles array which is which points inside which tile
  2. request tiles array from terrain
  3. and interpolate coordinate height from terrain data

This process happen in client and it's slow.

I want to do this in server side, but I don't know is there any service gives me height of given coordinate like sampleTerrainMostDetailed method ?

  • Global? Local? 100m resolution? 1 meter resolution? 1 cm resolution? – bugmenot123 Nov 30 '21 at 12:15
  • I mean I try to learn is there any service for that or, should I write program for that, I explain what I try to do, may be there is a keyword for that which is I dont know or there are some tools do that already. – H. Akkaya Nov 30 '21 at 13:14
