Geocoding and stereo display of tropical forest multisensor datasets
Concern about the future of tropical forests has led to a demant for geocoded multisensor databases that can be used to assess forest structure, deforestation, thermal response, evapotranspiration, and other parameters linked to climate change. In response to studies being conducted at the Braulio Carrillo National Park, Costa Rica, digital satellite and aircraft images recorded by Landsat TM, SPOT HRV, Thermal Infrared Multispectral Scanner (TIMS), and Calibrated Airborne Multispectral Scanner (CAMS) sensors were placed in register using the Landsat TM image as the reference "map". Despite problems caused by relief, multitemporal datasets, and geometric distortions in the aircraft images, registration was accomplished to within ¦20 m (¦1 data pixel). A digital elevation model (DEM) constructed from a multisensor Landsat TM/SPOT stereopair proved useful for generating perspective views of the rugged, forested terrain
