MapScene: Query elevation on client?

Question asked by gasparovic on Jul 25, 2018

Hi, I would really appreciate if there was a series of articles that would enlighten us on how to do client side operations on elevation models, e.g. query elevation for point, polyline and polygon from the model etc.


But my question is, is there any way, in 4.8, to query the elevation that wouldn't require heaps of requests to the server as it's currently happening via queryElevation method?


I can see that e.g. the 3DMeasurementTool widget does elevation queries (look at the height contour polyline!) very efficiently. Very likely done via WebGL and esri's own externalRenderer...
