AGRC has 2 Meter Auto-Correlated DEMs for various areas of the state collected during the 2006 HRO flight.The auto-correlation process is not as rigorous as other methods of elevation modeling such as photogrammetry, lidar mapping, radar mapping, etc, and therefore end-users should be aware that anomalies are expected within the elevation dataset. In comparison to the USGS NED dataset, the 2-meter DEM provides higher resolution and horizontal accuracy but anomalies are present within the data. DEM_2meter_index.zip is a shapefile that can be used to determine what files to download. These DEM files are in a .asc format and are around 10 mb per 2,000 X 2,000 meter block. This data has a UTM NAD83 meters projection.
