I generate terrain files from live images in a folder using ODM and gdalwarp.
When in offline, I use NaturalEarthII cesium asset as the base layer and in online I use Bing maps from online.
My question is we would like some sort of building and tree elevation apart from the base layer so is there any online dsm provider as Cesium World Terrain is DEM?
For offline on cesium clip and ship is there any dsm provider? Does Jaxa do the work?
