When merging Hydrographic Multi Beam data with terrestrial point clouds there is often a need to invert the Z value only on the hydrographic point cloud as most hydrographic software reads a positive Z value as a depth below the water surface. Sometimes I get a data set that is still in depths (positive Z is down) so I need to invert the Z value only. Is there a way in TBC to accomplish this on a point cloud? Perhaps I can use a -1.0 scale factor on the Z values only? If anyone has a good solution to this it would be very helpful.
