Neighbour polygons
Algorithm
The Neighbour polygons operation finds adjacent (or neighbouring) polygons in a polygon map and calculates the length of the boundaries of adjacent polygons.
Steps:
- The program scans the polygon map polygon by polygon.
- For each polygon the boundary is checked for neighbouring polygons. The lengths of the boundaries of a polygon with its neighbouring polygons are calculated.
- All polygon boundaries, for example all boundaries between polygons A and B, are summed.
- These values are presented in an output table. The polygon names, in the first two columns of the table, are arranged in alphabetic order.
