The AGRC has a statewide coverage of 5 Meter Auto-Correlated DEMs collected during the 2006 NAIP Aerial Photography 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 5-meter DEM provides higher resolution and horizontal accuracy but anomalies are present within the data.
DEM_5meter_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 125 mb per 20,000 X 20,000 meter block. This data has a UTM NAD83 meters projection.
