Abstract

Many branches of Geography waste a great deal of time and effort making map comparisons. Thus, such comparisons can include very varied topics, such as relationships between crops and precipitation levels, levels of diffusion of innovations in a region, or comparison of different cities for the purpose of regularizing their spatial development.

Map comparisons are commonly made to fulfill two purposes: a) as a taxonomic process, in order to classify a group of similar phenomena or distributions. b) as part of research to establish whether the distribution of similar patterns is caused by similar processes.
