Getting the map height for a given lat, long

Cesium for Unity

Hi,

Is it possible to look up the height for a given lat,long? I want to place an object on the surface of the map but i only have a lat and long.

Hi @RandomName87,

Currently, your best bet is to use a Raycast to query the height of the terrain at that point prior to placing the object.

This reply may also be useful to you - though it was written for Unreal, it includes some relevant caveats and possible workarounds for this method.

Just to give an update, as of Cesium for Unity v1.13.0, you can now use the asynchronous SampleHeightMostDetailed function to query the height on a tileset, at a given longitude / latitude position. Remember that this height is returned in meters above the WGS84 ellipsoid!
