The DEGURBA alternative polygon (object-based) model, which maps the actual shape of urbanized areas using a detailed spatial distribution of the population at address points. Unlike the grid-based approach, DEGURBA allows for the precise delineation of settlement structures without the influence of a fixed grid and eliminates uninhabited areas.
Municipality polygons classified using a experimental polygon-based (object-oriented) DEGURBA model. The classification is based on accurate spatial identification of settlement clusters and subsequent aggregation of population into administrative units.
