Add geotiff height map to Cesium for Unity

Cesium for Unity
1

Hi,

I made a basic application with Cesium for Unity and added Google photorealistic 3D tiles.

Now I need to add a geotiff height map that represents the water level in case of high rain rating.

I imported the geotiff directly in Cesium ION and it appears correct in the preview window

Now I added this new terrain as a child of blank tile set.

The issue is that this new terrain appears to cover the entire globe and not only the area of the geotiff.

Is this by design or I am doing something wrong?

Thank you

Ivan

Hi @IvanF, welcome to the community!

Yes, Cesium ion terrains are always a complete globe, even if your GeoTIFF only covers a small area. It will fill the rest with a Mean Sea Level surface (or another terrain like Cesium World Terrain, if you select that).

You can work around this by using a “Cartographic Polygon” to clip out the area outside of your GeoTIFF. See the tutorial here:
