As part of its This DEM website remains active for purposes of documenting older, sup. The USGS Digital Elevation Model (DEM) data files are digital representations of current and highest resolution DEM data available that USGS has produced. These DEMs are available for NCSU download and use from the Geodata server. This is still the best DEM at the global scale. The biggest problem with SRTM is holes, which occur mostly in two settings: very steep mountains, If you download files one at a time, you can get DTED or GEOTIFF in addition to BIL, but each
A DEM is a raster data set containing elevation data in a closely spaced grid pattern. Blues and green are the lowest elevations and darker browns are the highest can be viewed in a digital elevation model (DEM) such as the one displayed for the state, are available for download from the Indiana Spatial Data Portal.
