<abstract>One-meter cell size Erdas Imagine (.img) files created from the ground classified (class = 2) lidar points which results in the Digital Elevation Model (DEM). These are delivered in both 5000m by 5000m tiles and also by a countywide DEM raster. Nebraska Department of Natural Resources produced 2 meter resolution ESRI rasters by resampling 1 meter ESRI rasters (provided by NRCS).</abstract>
<purpose>The Lidar data combined with the 3d breaklines can be used to produce a highly accurate representation of the earth's surface (x, y and z).</purpose>
<supplinf>Project Projection, Datums and Units Projection - UTM Zone 14 North Horizontal datum - North American Datum of 1983 (NAD83) using the latest adjustment revision (NSRS 2007) Vertical datum - North American Vertical Datum of 1988 (NAVD88) using the latest geoid (Geoid03) for converting ellipsoidal heights to orthometric heights Units - meters (to 1cm resolution) See the LIDAR report for detailed information.</supplinf>
