Ferreira, NC, Ferreira, LG, Huete, AR, Ferreira, ME (2007). An operational deforestation mapping system using MODIS data and spatial context analysis. INTERNATIONAL JOURNAL OF REMOTE SENSING, 28(2-Jan), 47-62.

The Brazilian Amazon has the world's highest absolute rate of forest loss, currently averaging nearly 2 million hectares per year. In this study, we present a near-real-time automated deforestation mapping system for the Brazilian Amazon based on the analysis of spatial context information and MODIS Vegetation Index products and implemented on an ArcGIS 9.0 platform. This system, already validated and operational, was developed as part of the Integrated Warning Deforestation System for the Amazon (SIAD), an initiative of the Brazilian government within the scope of the Amazon Protection System (SIPAM), which also comprises: (1) a spatial information module, aimed at the assessment of the causes and impacts of the deforested areas: (2) a prediction module, indicative of deforestation trends; and (3) a data and information gateway based on map server technology.
