The original data was classified bare-earth LiDAR DEM and photogrammetrically derived breaklines generated from LiDAR Intensity stereo-pairs in ESRI ASCII 3D Generate format and Microstation SE .dgn format for Blue Earth County, Minnesota. The data was further processed by the Minnesota Department of Natural Resources to create and distribute feature classes in this geodatabase version. The LiDAR data for Blue Earth County was collected under contract by the county. Thus, the data format is not entirely consistent with some of the other LiDAR data available in Minnesota. Specifically, the Blue Earth county collect only required classification of Bare Earth in the LiDAR LAS files, so there is no information on buildings, vegetation, or model key points. Breaklines captured as part of this effort are also a bit different since they are 3D Polyline features rather than 3D Polygon features. They also include road centerlines, stream courses and other features that are not part of the Statewide collect specifications. Note: This metadata record was created at the Minnesota Geospatial Information Office using information supplied by Optimal Geomatics, Inc., Blue Earth County, and the Minneosta Department of Natural Resources.
