Abstract

We developed an algorithm for reducing geometric differences between a source and a target dataset. The algorithm tackles the polygon overlay problem in electoral geography before using areal interpolation methods. Our results show that improvement in matching between statistical areas and polling areas can reduce up to 40% of areal interpolation errors. This is applied to two case studies: the city of Avignon, France, and the city of Hobart, Australia.
