I am creating two different lake maps, and have gotten them both to this point, where I am getting the same error. The general help key was not helpful.
ArcMap 10.5
There are about 1,000 depth points.
Coordinate system is WGS 1984
The input data, is the depth points in the lake body. The barrier is the outline of the lake that is a polygon shape file
It completed Kernel Smoothing just fine, but not interpolation.
