Hi,
I am trying to build a list of all (first order contiguous/) neighbouring polygons of 1817 small areas in one UK city (census output areas). - only edges and nodes, no overlaps and no two-way relationships - nothing too complicated.
The "Polygon Neighbours" tool generates a table which is only partially complete - i.e. some polygons with 7-8 edge neighbours and 1 node neighbour are listed as having only 2 contiguous neighbours.
The integrity of the polygons should be ok as it's the UK census shapefile (looks good in zoom).
Any suggestions as to what the problem might be?
Many Thanks!
