Scott,
You have to adjust the z depth in the 3D viewer so that the bathy grid is below your airphoto layer. If you would like more info on the particulars... send me an email directly, and I can provide my work phone number where I can walk you through it from work... I'm at the Bedford Institute of Oceanography during the day. This is my home email address.

Subject: [spam] MI-L Vertical Mapper, bathymetry and drape files
Hello,
A question to anyone out there who has experience using Vertical Mapper for displaying 3D images of the seafloor:
My problem is this: I can create grids of sounding data to show seafloor relief (derived from multibeam or single-beam data files), however, when I want to display this data with drape files (i.e. airphotos) it appears in the 3D viewer as if the seafloor is raised above the ground. My data for the sounding depths is negative, so why doesn't it appear to 'sink' below the airphoto (which I would presume should be defaulted to ground level; or 'zero'). I can't seem to get any of my drape files (charts, air photos, etc.) to display so the sounding depths appear to be 'below' them.
Any suggestions, or am I out of luck?
Thanks,
Scott
