Abstract

Digital tools have become an important ally for cartography, where geographic information systems GIS are being used for demographic analysis within territorial units. Its importance is given in that these studies serve so that the sectionals governments have reference to the population changes, which are reflected in the territorial growth, which in the case of Ecuador, is done without any type of planning, having a limited number of basic services, with a low quality of life and environmental impact of its inhabitants. Problem that is evident in the province of El Oro, specifically in the cantons of Machala, El Guabo, Santa Rosa, Arenillas and Huaquillas, which are among the most populated and with little planned growth of their territory. The objective of the research is to demonstrate the expansion of cities in the lower part of the Province of El Oro through digital cartography and to make a comparison of its extension in the period 2008-2018. The methodology used was descriptive, in which the information was analyzed through the use of the shapefile download of coverage and land uses CUT of 2008 and 2018, for the generation of a map of coverage changes, using ArcGIS software, Excel, raster calculator, information that allowed to know the demographic and territorial growth of the cantons, so that the authorities can implement plans for an orderly growth for the social economic well-being of their citizens.
