  -          <p>FORMA is a near real-time tree cover loss alert system. It uses a cloud computing <a href="https://github.com/reddmetrics/forma-clj" target="_blank">algorithm</a> to analyze frequently updated satellite imagery along with complementary information on factors that affect tree cover loss, such as fires and precipitation. The system generates twice-monthly “alerts” for the world’s <a href="http://wolfweb.unr.edu/~ldyer/classes/396/olsonetal.pdf" target="_blank">humid tropical forests</a> that identify 500 x 500 meter areas where new, large-scale loss is likely to have occurred.</p>

It uses a cloud computing <a href="https://github.com/reddmetrics/forma-clj" target="_blank">algorithm</a> to analyze frequently updated satellite imagery along with complementary information on factors that affect tree cover loss, such as fires and precipitation.

             <p>FORMA is designed for quick identification of new areas of tree cover loss. The system analyzes data gathered daily by the <a href="http://modis.gsfc.nasa.gov/about/" target="_blank">MODIS</a> sensor, which operates on NASA’s Terra and Aqua satellites. The FORMA alerts system then detects pronounced changes in vegetation cover over time, as measured by the <a href="http://earthobservatory.nasa.gov/Features/MeasuringVegetation/measuring_vegetation_2.php" target="_blank">Normalized Difference Vegetation Index (NDVI)</a>, a measure of vegetation greenness. These pronounced changes in vegetation cover are likely to indicate forest being cleared, burned, or defoliated.</p>
