During the past decade interferometric synthetic aperture radar and laser ranging, from aircraft and satellites, has brought topographic mapping to the forefront of geodesy. Nested data sets make it possible for the first time to study natural geo-surficial processes on centimeter spatial scales ranging from small local project areas to global scale projects, all in a consistent geodetic frame of reference. Local applications include mapping of alluvial fans, landslides, local faulting, and beach erosion. Regional scale applications include monitoring large ice masses and mapping major fault lines and drainage basins. Global scale applications include use of the data to improve knowledge of gravity anomalies and geoid modeling. Papers are invited on the development of improved instruments, reports of results from current projects, the development of improved processing algorithms, methods of fusing the different types of observations (which often have different spatial resolutions), and scientific results derived from the improved knowledge of the topography.
