Digital Elevation Model (DEM) Discovery Portal
This "DEM Discovery Portal" uses an ArcGIS map interface to locate, preview, and link to DEM web pages for download. DEMs may be bathymetric, topographic, or a merged combination of both. They also range from high-resolution coastal DEMs for local studies to coarser DEMs with global coverage. DEM usage ranges from ecologists mapping fish habitat to hurricane modelers estimating coastal storm-surge inundation.
