A zoning method and a numerical criterion for zoning quality are available in this package. The zoning method is based on a numerical criterion that evaluates the zoning quality. This criterion quantifies simultaneously how zones are heterogeneous on the whole map and how neighbouring zones are similar. This approach allows comparison between maps either with different zones or different labels, which is of importance for zone delineation algorithms aiming at maximizing inter-zone variability. An optimisation procedure provides the user with the best zonings thanks to contour delineation for a given map.
