AN EVALUATION OF LIDAR- AND IFSAR-DERIVED DIGITAL ELEVATION MODELS IN LEAF-ON CONDITIONS WITH USGS LEVEL 1 AND LEVEL 2 DEMS (2003)
An assessment of four different remote sensing based methods for deriving digital elevation models (DEMs) was conducted in a floodprone watershed in North Carolina. New airborne LIDAR (light detecting and ranging) and IFSAR (interferometric synthetic aperture radar (SAR)) data were collected and corresponding DEMs created. These new sources were compared to two methods: Gestalt Photomapper (GPM) and contour-to-grid, used by the U.S. Geological Survey (USGS) for creating DEMs
