I'm using 3d Analyst as part of an archaeology project. We're excavating a rock shelter - think of it as a shallow cave. It is a relatively small area, so the maps will be at about 1:50 scale.
I've used a Total Station and basic survey equipment to obtain multiple X, Y, and Z values for the area.
Unfortunately I'm unable to figure out how to deal with the fact that there is an overhang. That is - I have XYZ data for the floor of the interior of the shelter (shallow cave), the roof of the shelter, and the ground surface above the shelter - but there's no way for me to designate which is which - so I end up with a jagged and incorrect interpolation of the points.
Any ideas here...?
