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.
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.
The original metadata record was created at the Minnesota Geospatial Information Office by combining information supplied by AeroMetric and the DNR.
This metadata record reflects the Southeast Minnesota data that are available from the NOAA Digital Coast Data Access Viewer (DAV).
The NOAA Office for Coastal Management (OCM) downloaded 1545 laz point data files from this USGS site:

The data were processed to the NOAA Digital Coast Data Access Viewer (DAV) to make the data available for custom downloads and to AWS S3 for bulk downloads.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
