Urban expansion evaluation from orbital images

This paper aimed to validate remote sensing tools for the development of land management plans. This validation was performed from the verification of urban expansion in the city of Campinas, São Paulo, Brazil, between 1991 and 2011. For the development of the study, the geoprocessing tools were complemented with population data to generate urban population, urban expansion and population density maps for each of the macrozones of the city of Campinas. Comparing the generated maps and environmental problems present in macrozones is concluded that the sensing tools are extremely useful in designing urban master plans and, if aligned with other data, can provide the simulation of future expansion and urban density of certain area relating them to their resilience and thus lead to a city planning that meets the quality of life for all population segments. Cities must be understood in a dynamic context that is constantly changing
