How to Reconstruct Elevation Grids from Point Clouds?

If the point cloud represents a single surface (such as earth ground terrain), then the Gridding tab (“Point Cloud Parameters” panel) in PDF3D ReportGen contains options to reconstruct a smooth gridded surface from the points using IDW (Inverse Distance Weighted) interpolation.

The grid resolution can be set to an arbitrary density independently of the number of points.
