About CLASlite Classroom

Welcome to the world’s first online course for deforestation and forest degradation mapping. This course is designed to equip government, academic and non-commerical, non-government organizations with the knowledge needed to monitor forests using the Carnegie Landsat Analysis System-lite or CLASlite. The course provides the scientific basis for each module in CLASlite, along with other information to make forest monitoring easy using Earth observing satellite data.


We only provide CLASlite training and licensing to non-profit, non-commercial organizations. To successfully complete the course, you should have a basic familiarity with geospatial data and Windows PCs.
