Hi Richard:

The tool in Maptitude 4.7 computes first order adjacency by edge (rook), node (bishop), or both (queen). Do you need bishop adjacency to the nth order?

Does anyone have an add-in which does adjacency as is done in Mapt 4.7 now but also includes the bishop adjacency as well as rook?  The jargon is: rook = polygons share an edge only.  bishop = polygons share only a point   for doing spatial statistical studies have both (queen) is very important.
