Hi all,

I am doing a project which have cesium 3d support and now we want to integrate a DEM format file into cesium 3d. I surfed in internet but i am not getting any possible solution. How can i do it ?

Thanks

Hi Kamal,

If I’m understanding you correctly, your DEM file represents terrain, and you want to show that terrain surface in Cesium. Is that correct?

Cesium doesn’t have built-in support for rendering terrain directly from a DEM file. In fact, unless the DEM file is quite small, rendering it directly is impractical. So you have a few options:

  • Import your DEM into an ArcGIS Server and access it in Cesium via ArcGisImageServerTerrainProvider.

  • Convert it to the format described here and access it via CesiumTerrainProvider.

  • Implement your own custom TerrainProvider to access your terrain data in whatever format you prefer.

  • Purchase AGI’s soon-to-be-available terrain server, which allows you to import terrain in a variety of formats by simply dragging-and-dropping, and then easily visualize that terrain in Cesium.
