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.
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.

Horizontal Positional Accuracy
Compiled to meet +/- 3.8 ft horizontal accuracy at 95 percent confidence level.
Vertical Positional Accuracy
From the Woolpert Report:
The LiDAR data vertical accuracy RMSE is 3.6 cm (0.12 ft). The data collected under this Task Order meets the National Standard for Spatial Database Accuracy (NSSDA) accuracy standards. The NSSDA standards specify that vertical accuracy be reported at the 95 percent confidence level for data tested by an independent source of higher accuracy. (http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part3/index_html).
Tested 7.1cm (0.23ft) fundamental vertical accuracy at a 95 percent confidence level, derived according to NSSDA, in open terrain using (RMSEz) x 1.96000 Tested against the TIN using independent check points.
From the MN DNR Vertical Accuracy Validation Report:
NVA vertical accuracy RMSE is 10.6 cm.

Conceptual Consistency
All formatted data are validated using commercial GIS software to ensure proper formatting and loading prior to delivery.The LIDAR data is visually inspected for completeness to ensure that are no gaps between flight lines.
NOAA OCM downloaded the laz files from the MN DNR Lidar site (ftp://ftp.gisdata.state.mn.us/pub/data/elevation/lidar/projects/duluth_fall_2012/)
Using Light Detection And Ranging (LiDAR) systems, 154 flight lines of high density data, at a nominal pulse spacing (NPS) of 1.5 meter, were collected over Minnesota counties of Lake, St Louis, Aitkin, Carlton, and Pine (approximately 3,078 sq. miles), along with a 100 meter buffer beyond the project tile boundary. Multiple returns were recorded for each laser pulse along with an intensity value for each return. A total of eleven (11) missions were flown from October 29, 2012 through Novembe 08, 2012. A minimum of three (3) airborne global positioning system (GPS) base stations were used in support of the LiDAR data acquisition. All data for this task order is referenced to UTM 15N, NAD83, NAVD88, in meters. Airborne GPS data was differentially processed and integrated with the post processed IMU data to derive a smoothed best estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface for each flight line. The coverage was classified to extract a bare earth digital elevation model (DEM) and separate last returns. In addition to the LAS deliverables, one layer of coverage were delivered in the ArcGrid binary format: bare-earth.

The ALS70 and Optech Gemini calibration and system performance is verified on a periodic basis using Woolpert's calibration range. The calibration range consists of a large building and runway. The edges of the building and control points along the runway have been located using conventional survey methods. Inertial measurement unit (IMU) misalignment angles and horizontal accuracy are calculated by comparing the position of the building edges between opposing flight lines. The scanner scale factor and vertical accuracy is calculated through comparison of LiDAR data against control points along the runway. Field calibration is performed on all flight lines to refine the IMU misalignment angles. IMU misalignment angles are calculated from the relative displacement of features within the overlap region of adjacent (and opposing) flight lines. The raw LiDAR data is reduced using the refined misalignment angles.
2012-01-01T00:00:00
Once the data acquisition and GPS processing phases are complete, the LiDAR data was processed immediately to verify the coverage had no voids. The GPS and IMU data was post processed using differential and Kalman filter algorithms to derive a best estimate of trajectory. The quality of the solution was verified to be consistent with the accuracy requirements of the project.
2012-11-11T00:00:00
The individual flight lines were inspected to ensure the systematic and residual errors have been identified and removed. Then, the flight lines were compared to adjacent flight lines for any mismatches to obtain a homogenous coverage throughout the project area. The point cloud underwent a classification process to determine bare-earth points and non-ground points utilizing "first and only" as well as "last of many" LiDAR returns. This process determined The LiDAR LAS files for this task order have been classified into the Default (Class 1), Ground (Class 2), Low Vegetation (Class 3), Medium Vegetation (Class 4), High Vegetation (Class 5)
Buildings (Class 6), Noise (Class 7), Model Keypoints (Class 8), Water (Class 9), Ignored Ground(Class 10), bridges (Class 14), and Overlap (Class 17) classifications. The bare-earth (Class 2 - Ground) LiDAR points underwent a manual QA/QC step to verify that artifacts have been removed from the bare-earth surface. The surveyed ground control points are used to perform the accuracy checks and statistical analysis of the LiDAR dataset.

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/
The files contained elevation and intensity measurements for the Duluth Post-Flood project area. The data were in UTM 15, NAD83, meters coordinates and NAVD88 (Geoid09) elevations in meters. The data were classified as: 1 - Unclassified, 2 - Ground, 3 - Low Veg, 4 - Medium Veg, 5 - High Veg, 6 - Buildings, 7 - Noise, 8 - Model Keypoint, 9 - Water, 10 - Ignored Ground, 14 - Bridge Decks, 17 - Overlap. The NOAA Office for Coastal Management processed all classifications of points to the Digital Coast Data Access Viewer (DAV). Classes available on the DAV are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 14, 17.
OCM performed the following processing on the data for Digital Coast storage and provisioning purposes:
1. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges.
2. Internal OCM scripts were run on the laz files to convert from orthometric (NAVD88) elevations to ellipsoid elevations using the Geoid09 model, to convert from UTM 15, NAD83, meters coordinates to geographic coordinates, to assign the geokeys, to sort the data by gps time and zip the data to database and to http.

The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
