A methodology based on satellite information, Landsat, was developed to evaluate changes in forest cover of the Coast and Mountains of Peru for the periods 2000-2007, 2007-2011, and 2011-2014. To this end a basemap for 2007 was created and a historical series of images was analysed using a change detection algorithm. The images were atmospherically and radiometrically corrected so that they could be used together. A protocol for the pre-processing of images and classification of forest type was designed, as well as a methodology for the validation and verification of the base maps and forest loss maps. This procedure was also evaluated using Sentinel 2 images in such a way that allows this type of map to be generated as and when new images become available.
