Is there open source software available to set up an internal terrain elevation query service, similar to what is done with this python query script to an external service:

Hi Robert,

**[sampleTerrain](https://cesiumjs.org/Cesium/Build/Documentation/sampleTerrain.html)** will sample an array of Cartographic positions at a specific level of terrain, and[**sampleTerrainMostDetailed**](https://cesiumjs.org/Cesium/Build/Documentation/sampleTerrainMostDetailed.html) will do the same, but for the highest level of available terrain data.

Thanks,  
Gabby
