Hello, I purchased credits and imported terrain data (with the lowest grid spacing allowable) through Sketchup Placemaker. However the data is flat. What went wrong? Does Cesium not have data for some suburban US areas?
Can you tell me a little bit more about the data you imported - the resolution, how it was created/sourced etc? Can you share the “Open complete code example link” from Cesium ion asset page?
Cesium provides a global terrain dataset called Cesium World Terrain, which includes terrain data for the entire globe. You can try it here if you haven’t before Cesium Sandcastle.
