DEMDistanceCalculator

From Fmepedia

DEMDistanceCalculator is a Workbench Transformer. Takes in a number of line features and a single reference DEM. For each input line feature, a DEM is created after the reference DEM, and then output.

The data contained in the resulting DEM consists of the 3D distance between the line being considered and the corresponding point on the reference DEM.

The lines may be organized into groups with the Group By parameter, with each group of lines having its own reference DEM.
