A 2012 study conducted by CIFOR and the Amazonas Sustainable Foundation compared the work input and output performance of three different deforestation mapping approaches for the Juma Sustainable Development REDD project area in Brazil. Output from CLASlite version 2.3 was compared to the PRODES deforestation product that is published each year by the Brazilian Institute for Space Research (INPE) and results from a software package called ImageSVM. Basic differences in the three approaches include: (a) CLASlite is operated by the user for any region of the world and requires no ground calibration, (b) PRODES is a map product provided once per year by the Brazilian government covering the the Brazilian Legal Amazon, and (c) ImageSVM is a general mapping software requiring extensive ground-based training data.
The results were published in a CIFOR-Amazonas Sustainable Foundation report in June 2012 authored by Floria Reimer, Jan Börner, and Sven Wunder, and was disseminated at the international Rio+20 conference held in Rio de Janeiro, Brazil.
