Format:https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer/tile/{z}/{y}/{x}
|
|
At first, I use HttpDebugger find this server, because ArcGIS Earth use this elevation3d server
|
|
Although it is height map form, in China, it is not easy to visit STK Terrain, it is also an appropriate solution.
|
|
Then I watched the tile content and the header is "CntZImage" which is the arcgis/lerc compression
|
|
Eventually, I create the ArcGisImageServerTerrainProvider class, so we can load thise terrain server easily, and you can download this file in Source/Core freely.
|
|
Note: ArcGIS HeightMap Terrain Server is WebMercatorTilingScheme.
|
|
There is a bug but I could not fix it without modifying the source code. For example, in level 13, I found some tiles have no height data,
|
|
the data is always 0, you can still request this tile. So, the state is TerrainState.RECEIVED
