Example of the original high-resolution census-based, polygonal data with streets, water bodies, and other open spaces left as “no data” (left, shown as white space) and the same polygons after morphological tessellation (right) with the location of the study area in Mexico given in the inset map in the lower right. Each aggregated unit was then joined with its total population count corresponding to the 2010 census. These joined localidades and manzana data for the study region represent the base data product from which all previous syntheses were produced.
