Trying to get the value from my locally hosted terrain: Is this possible? I’m running into problems. Just wanted to make a function to return the height value when called.

const localTerrainProvider = await Cesium.CesiumTerrainProvider.fromUrl(  
‘[http://localhost/](http://localhost/)’, {  
requestVertexNormals: true,  
requestWaterMask: true  
});

Hi @brent252, thanks for the question.

I would expect [`sampleTerrain`](https://cesium.com/learn/cesiumjs/ref-doc/global.html?classFilter=Sam#sampleTerrain) or [`sampleTerrainMostDetailed`](https://cesium.com/learn/cesiumjs/ref-doc/global.html?classFilter=Sam#sampleTerrainMostDetailed) to work even on locally hosted data.  
Please try those if you haven’t then if you’re still having issues please provide more information on the errors you’re seeing.
