For the past ve years we have traveled to China to present the course in panda reserves
for staff working in the reserves and forestry departments, as well as researchers from science academies and universities. The course provides step-by-step instructions for using Global Positioning System (GPS) units to collect data on the ground, the ERDAS IMAGINE® software suite (ERDAS, Norcross, GA) to rectify, view and mosaic imagery, and GIS software for analysis and data presentation.
