Abstract

Overlapping maps in different scales is associated geometric problems, ecological fallacy and change of support problem. This research analyzes researches published (2014-2019) in the top Brazilian geography journals which are related to the change of support problem. Besides providing evidence that shows the relevance of this problem to geography, this research goal is to propose a procedure that, by making maps in different scales compatible, reduces problems of spatial support change. The procedure is performed on a Freeware of Geographic Information System (GIS) and comprises: (i) inserting more vertices in the maps elements of census tracts (STs) of Brazilian Institute of Geography and Statistics or IBGE and the streets of Foz do Iguaçu-PR; and (ii) replace the vertices coordinates that present possible overlapping errors. Besides making 87% of Sts compatible to the streets, and presenting adjustment errors in only 2.81% of cases, the procedure does not require any algorithms or codes development, which are necessary in previous studies.
