LiDAR Elevation, Southeast Minnesota, 2008

This high accuracy, bare-earth processed LiDAR data includes one-meter resolution DEMs, two-foot contours, edge-of-water breaklines and LAS points for nine counties in Southeast Minnesota: Dodge, Fillmore, Freeborn, Houston, Mower, Olmsted, Steele, Wabasha, and Winona. The project was coordinated by the Minnesota Department of Natural Resources and several partners including the U.S. Geological Survey, the Minnesota Department of Transportation, and staff from the affected counties.<br/><br/>The data was collected by AeroMetric, Inc. (now Quantum Spatial) in November 2008 and was delivered in tiles that covered an area 1/16th of a 1:24,000-scale USGS quadrangle (approximately 3.25 square miles). DNR conducted the QA/QC starting April 2009. As part of the processing, one- and three-meter county mosaic DEMs were created and used for visual quality assessment.<br/><br/>Note: This metadata record was created at the Minnesota Geospatial Information Office by combining information supplied by AeroMetric and the DNR.

dsPurpose The Southeast Minnesota LiDAR project's goal was to provide high accuracy, bare-earth processed LiDAR data suitable for the FEMA National Flood Insurance Program. In August 2007, the nine counties had experienced a major rainfall event with over 10 inches of rain that caused extensive flooding. The Minnesota Legislature appropriated money to aid in flood relief and to provide mitigation against future floods including the acquisition of high-resolution elevation data using LiDAR technology.
