Abstract

This study presents changes in land cover and its environmental impact in interest areas of natural and semi-urban zones of southern Costa Rica, including the nature reserve of the Corcovado Park and the Sierpe lagoon.

Data from HyMap and MASTER airborne sensors are used in this research, as well as ASTER and ETM+ images taken in a period between 1990 and 2010. Land cover and water surfaces are analyzed by supervised digital classification using radiometry data field, considered as indicative of possible environmental pollution or overexploitation of resources effects that could be affecting the area. Therefore, first obtained results and generated mapping are useful to assess the condition and evolution of land use.
