Description
Summary:This document presents, a validation of the global burned area product (L3JRC) in Colombia, using the method of the confusion matrix, where Landsat images are used as a proxy for fieldwork. The product L3JRC is a burned area map, based on remote sensing SPOT-VEGETATION data and generated by Tansey et al., in 2007. A pattern toward larger omission errors was found in the validation process, although commission errors were also present. Disregarding the type of error, it was shown that the product L3JRC underestimates 40% of the burned area of the country. With this accuracy of assessment, it was concluded that the annual average burned area in Colombia during the annual study period was 14,807 km super( 2), taking into account omission values burned area may exceed 21,000 km super( 2). Orinoquia region has more than (90%) of the total burned area of the country, where Vichada, Meta, Arauca, and Casanare were the most affected Colombian departments.
