Does ol3-cesium accept DEM files?

Question

I'm using OpenLayers 3.6.0. I want to use ol3-cesium. Ol3-cesium use cesium for glob visualization. I have a question:

In ol3-cesium, Can I see Ups and downs of land? In other words Does it accept DEM files?

Answer 1

You can use the standard Cesium terrain provider, or if you have your own elevation data, you can serve it up through GeoServer and use: https://github.com/kaktus40/Cesium-GeoserverTerrainProvider

Answer 2

The short answer is yes, but it has to be pre-processed into a different format because DEM files and other "raw" terrain data is not suitable for visualization. The standard for Cesium is quantized-mesh, but we also support traditional height maps. The premier application for processing terrain for Cesium is the STK Terrain Server, which is a commercial product. There are some other open source projects, of various quality, which also attempt to generate terrain compatible with Cesium.
