The project vendor, AeroMetric, Inc., acquired highly accurate Light Detection and Ranging (lidar) elevation data for Blue Earth County in south central Minnesota in Spring 2012. The project area consists of approximately 2,260 square kilometers (862 square miles). Lidar data are in the UTM Zone 15 coordinate system, NAD83 (HARN) NAVD88 (Geoid09), meters. The tiling scheme is 16th USGS 1:24,000 quadrangle tiles. The vendor delivered the data to the Minnesota Department of Natural Resources (DNR) in several formats: 1) One-meter digital elevation model 2) Edge-of-water breaklines 3) Classified LAS formatted point cloud data DNR staff created two additional products: two-foot contours and building outlines. This metadata record was created at the Minnesota Geospatial Information Office by combining information supplied by AeroMetric and DNR., The Minnesota Elevation Mapping Project was initiated to support the development of high accuracy land surface information for the purposes of improving water quality, flood emergency preparedness and response, floodplain mapping, transportation planning and design, recreational planning and design, urban planning and to provide more efficient and effective project planning and execution. This project was funded by the Clean Water Fund of the Clean Water, Land and Legacy Amendment. The project consisted of acquisition, post-processing, and classification of lidar data and creation of products derived from the acquired data., Date lidar data was collected.
