This document discusses several studies that utilized remotely sensed data: 1. A study of mangrove forest distributions from 1975-2005 in Asia that used Landsat data to classify landscapes and determine 12% of mangroves were lost, with most deforestation due to agriculture and aquaculture. 2. A comparison of species distribution models using interpolated climate data versus remotely sensed temperature and precipitation data, finding the latter improved model fitting and transferability for many tropical species. 3. A review of freely and publicly available basic imagery from sources like Landsat that are useful for a variety of environmental applications and field studies.
