We have access to 1m and 10m DTM data in GeoTIFF format. Uploading to Cesium Ion works great. The 1m file sizes get unnecessarily big when dealing with larger terrain, so we figured we could upload 1m data close to our area of interest, 10m for a wider area, and rely on the Cesium world terrain for the rest.
We target the cesium world terrain when uploading, and this seems to create a “copy” of that database. In Unreal, we load the cesium terrain, the 10m data and the 1m data. Of course they overlap as three separate objects.
Is there a way to combine the 1m and 10m terrain in a single “copy” of the Cesium world terrain?
Hi! When you say “we target the cesium world terrain when uploading”, do you mean that you chose the Cesium World Terrain (CWT) as the base terrain layer for both of the GeoTIFF assets? Have you tried selecting CWT as the base terrain layer for one of the asset, and then selecting the merged terrain layer as the base terrain layer for the other asset? For example, you can select CWT as base layer for the 1m DTM data (let’s call this “myterrain”), then select “myterrain” as the base layer for the 10m DTM data.
