Hi I have a set of .asc files. I am looking to use FME to generate a point cloud then build a Terrain in an ESRI's dataset from the asc files.

Is this something I can achieve using FME Desktop or do I have an ArcGIS 3D extension license.

You can use the pointCloudCombiner to turn your asc files into a point cloud and then write them out in a format like LAS.

 

 

You can use the SurfaceModeller to turn your points into a TIN or DEM, I don't believe FME writes Terrain Geodatabases directly, but I could be wrong about that.

Thanks for the suggestion. Would I be able to extract the height value at any given coordinate from a TIN or DEM?

The DEM (raster) will have the height value stored as the pixel value, the DEM (points) will be an evenly spaced grid of 3D points.
