2011 MN DNR Lidar: Twin Cities Metro (Dakota Block), MN mn2011_dakota_m9679_metadata eng Dataset EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION elevation CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MINNESOTA VERTICAL LOCATION > LAND SURFACE LIDAR > Light Detection and Ranging Airplane > Airplane Fugro Horizons Inc. acquired highly accurate Light Detection and Ranging (LiDAR) elevation data for the Twin Cities metropolitan region in east-central Minnesota in Spring and Fall 2011, with some reflights in Spring 2012. The data cover Anoka, Benton, Carver, Dakota, Goodhue, Hennepin, Isanti, Kanabec, Meeker, Mille Lacs, Morrison, Ramsey, Scott, Sherburne and Washington counties. Most of the data was collected at 1.5 points/square meter. Smaller areas were collected with 2 points/square meter and with 8 points/square meter: 1. 1.5 points/square meter covers Morrison, Mille Lacs, Benton, Isanti, Sherburne, Anoka, Meeker, Hennepin, Washington, Carver, Scott, and Goodhue counties. 2. 2 points/square meter covers the Dakota Block (southern 2/3 of Dakota County) 3. 8 points/square meter covers portions of Minneapolis/St. Paul and the City of Maple Grove See map of block boundaries: ftp://lidar.dnr.state.mn.us/documentation/status/metro_data_delivery_dates.pdf Data are in the UTM Zone 15 coordinate system, NAD83 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 quality-checked the data and created two additional products: two-foot contours and building outlines. Note: The original metadata record was created at the Minnesota Geospatial Information Office using information supplied by the vendor and by DNR. Abstract Addendum, USGS National Geospatial Technical Operations Center (NGTOC), data edited November 2015: Data may have been modified from the original, delivered data by the NGTOC to correct issues such as breakline enforcement and hydro-flattening of water bodies, pits and spikes, and to remove edge tinning and other anomalies. End Abstract Addendum. This metadata record reflects the Dakota Block portion of the Twin Cities Metro data set and supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the Entwine Point Tiles (EPT) hosted by USGS on Amazon Web Services.
