My inputs are 3D point shape files and 3D point clouds in LAS format. These have been re-projected from OSGB to London Survey Grid using the transformer - SnakeGridProjector. The XY positions of the data are converted correctly but the Projector is set up to handle 2D data and the elevation values pass through untouched. It is a 'black box' projector so can't itself be manipulated to incorporate elevation shifts. Ideally a fixed value needs to added to the elevation to complete OSGB/LSG re-projection. We can apply the Z shift in alternate software, but would like to add this stage within the FME workspace if possible.
