Overview

I wrote a program to generate partitions of graticules to municipalities and municipalities to graticules using real-world border data. This is still a work in progress.

The areas are calculated in a Transverse Mercator projection (ETRS-TM35FIN), and so there are a few small quirks. The calculated areas differ slightly from true values, and most noticeably graticules at the same latitude apparently have different areas. This is probably due to distortion caused by the TM projection, or I may have an unnoticed error in my algorithm.
