A Gridded3DSet with manifold dimension = 2 is a rectangular
grid of points (like a checkerboard), arbitrarily twisted
and warped in 3-D. For radar data it could be a set of radial
distances crossed with a set of angles (i.e., the checkerboard
would be formed by a set of radial lines and a set of concentric
circles). In 3-D circular grid may lie on a cone shape.

Good luck, Bill
