Hi,

That abstract seems to layout a workflow for development and the tools to use. Do you have any specific questions about anything specifically related to Cesium?

Thanks,

Gabby

Thanks for the reply Gabby,I want to do analysis on terrain elevations.And visibility analysis on terrain using cesuim.

Look at this Sandcastle example for how to get terrain heights using Cesium.sampleTerrainMostDetailed(). You can do something similar to get the heights for points along a route that you could then put into a graph (not a Cesium feature) to show the terrain profile along the route. Simple visibility analysis would be possible using this technique if you specify enough points along the desired line-of-sight with sufficiently small spacing to capture the roughness of the terrain.
