A Portal to High-Resolution Topography Data and Tools
High resolution topographic data are available in a range of formats depending upon who acquired the data and what product types were delivered. The classes of data types available include: standard digital elevation models (DEMs), LiDAR point cloud data, and Google Earth files. For LiDAR point cloud data, web-based tools are also available to process these data into custom DEMs.
