LiDAR Elevation, South Dakota Portion of Minnesota River Basin, 2010

The Minnesota Department of Natural Resources contracted with Sanborn Map Co., Inc. to provide Light Detection and Ranging (LiDAR) mapping services for the South Dakota portion of the Minnesota River Basin. Utilizing multi-return systems, LiDAR data in the form of 3-dimensional positions of a dense set of mass points was collected for approximately 1,946 square miles.<br/><br/>The vendor delivered the data to the DNR in several formats:<br/><br/>1) One-meter digital elevation model<br/>2) Edge-of-water breaklines<br/>3) Classified LAS formatted point cloud data<br/><br/>DNR staff created three additional products: two-foot contours, building outlines and hillshades.<br/><br/>The data are in UTM Zone 14 coordinates.<br/><br/>Note: This metadata record was created at the Minnesota Geospatial Information Office by combining information supplied by Sanborn and the DNR.

dsOriginator Sanborn Map Co., Inc. and Minnesota Department of Natural Resources
dsPurpose This LIDAR operation was designed to provide a high density set of masspoints within the defined areas. The data sets are suitable for the development of contours for use in hydraulic/hydrologic model development, and for assessing environmental impacts.Typical uses for the data set include: FEMA Flood Plain Map Modernization. DFIRM map updates. Watersheds and other hydro studies per FEMA specifications. County Mapping projects which include several uses, in addition to Flood mitigation assessment. Mapping projects that include accuracy verification, reporting and meta data.
