Digital elevation maps are the bread and butter of many geoscience topics, such as the topography of watersheds and river basins. Having high-resolution, accurate maps world-wide is considered a holy grail of the topic. In remote regions of the world covered with forests, it is difficult to assess the land elevation as surveyors have done traditionally.
Simard et al. [2024] advance this topic using the radar on the Space Shuttle Endeavor. They compare their results with prior maps generated by LIDAR on the space station. The new map has a 60-meter pixel resolution, which provides greater density than LIDAR derived maps. Although radar-based maps remain biased over dense forests, future directions include merging of radar and LIDAR based observation to increase elevational accuracy and spatial resolution.
