The Minnesota Elevation mapping project was developed by the Minnesota Digital Elevation Mapping Committee and executed by Minnesota State agencies with the assistance of the federal government county governments to acquire a highly accurate land surface elevation dataset for the State of Minnesota. High accuracy elevation data are essential to improving water quality, improving disaster preparedness, protecting existing infrastructure, planning flood and drought damage mitigation reports, enhancing natural resource protection, and strengthening decision-making capacity at all levels of government.
This project was funded by the Minnesota Clean Water Legacy Act in 2009 the project is expected to conclude in 2013.
Woolpert, a vendor on the Minnesota LiDAR Master Contract, has been selected to provide LiDAR services for Work Order #7- Minnesota Duluth Flood Area LiDAR Acquisition.
LiDAR data are in UTM Zone 15 coordinate system, NAD83 NAVD88 Geoid09 meters tiled by USGS 1/16, 1;24,000 quadrangles. Data provided include:
1) One meter digital elevation model
2) Edge-of-water breaklines
3) Classified LAS formatted point cloud data
The NOAA Office for Coastal Management (OCM) downloaded 964 laz files from ftp://ftp.gisdata.state.mn.us/pub/data/elevation/lidar/projects/duluth_fall_2012/ and processed the data to the Data Access Viewer (DAV) and to https.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
