Abstract

Geographic Extent: Approximately 11,485 square miles in southwest Minnesota.

MN_RiverWest_1 (Work Unit 300408) - covering approximately 4151 square miles

MN_RiverWest_2 (Work Unit 300409) - covering approximately 3170 square miles

MN_RiverWest_3 (Work Unit 300410) - covering approximately 4164 square miles

Dataset Description of Original Data: A half-meter (0.5m) cell size Digital Elevation Model (DEM) raster was created from the ground classified lidar points plus the breaklines. The files are delivered in tile format (1000m by 1000m), the rasters are delivered in 32-bit floating point GeoTIFF format (.tif) and adhere to USGS-NGP Lidar Base Specification 2022, rev. A.

This metadata record supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the USGS GeoTiff files hosted by USGS on Amazon Web Services.

Purpose

This task is for providing a spring 2023 leaf-off and snow-free lidar survey over an area of approximately 11,485 square miles. This project will support the 3DEP mission, the Natural Resources Conservation Service (NRCS) high-resolution elevation enterprise, as well as many state and local agencies.

Horizontal Positional Accuracy:	The lidar data set was produced to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 20 (cm) RMSEx / RMSEy Horizontal Accuracy Class which equates to Positional Horizontal Accuracy = +/- 48 cm at a 95% confidence level.
Vertical Positional Accuracy:	This data set was produced to meet ASPRS Positional Accuracy Standard for Digital Geospatial Data (2014) for a 10-cm RMSEz Vertical Accuracy Class. USGS Determined Vertical Accuracy: DEM Tested NVA RMSEz = 3.94 cm DEM Tested 95th percentile value for VVA = 17.38 cm For more information see the USGS project report and the lidar reports. The links to these reports are provided in the URL section of this metadata record.

Process Steps

Process Step 1

CC ID: 1349292

Description:

Lidar data was collected using Optech Galaxy T2000 sensor. The raw data was verified in MARS software for complete coverage of the project area, and boresighted to align the flightlines. Raw data files were parsed into manageable client-specific tiles. These tiles were then processed through automated filtering that separates the data into different classification groups: unclassified points, ground points, low noise, water, bridge decks, high noise and ignore ground. The data was next taken into MARS to reclassify the erroneous points that may remain in the lidar point cloud after auto filter. Eight points per square meter (QL1).

Process Step 2

CC ID: 1349295

Description:

MN_RiverWest_1

LiDAR swath data was measured to have an aggregate of 0.198 meter nominal pulse spacing and 25.525 pulses per meter. The method used was counting first return points within the each swath then dividing by the area of the extent of the corresponding swath to get density. NPS was mathematically derived from this density number. This was performed on each swath then averaged to generate the two numbers above. This USGS method does not consider swath sidelap in these calculations.

MN_RiverWest_2

LiDAR swath data was measured to have an aggregate of 0.183 meter nominal pulse spacing and 30.006 pulses per meter. The method used was counting first return points within the each swath then dividing by the area of the extent of the corresponding swath to get density. NPS was mathematically derived from this density number. This was performed on each swath then averaged to generate the two numbers above. This USGS method does not consider swath sidelap in these calculations.

MN_RiverWest_3

LiDAR swath data was measured to have an aggregate of 0.205 meter nominal pulse spacing and 23.796 pulses per meter. The method used was counting first return points within the each swath then dividing by the area of the extent of the corresponding swath to get density. NPS was mathematically derived from this density number. This was performed on each swath then averaged to generate the two numbers above. This USGS method does not consider swath sidelap in these calculations.

Process Date/Time:

2023-11-28 00:00:00

Process Step 3

CC ID: 1349305

Description:	Using MARS software a half-meter (0.5m) 32-bit floating point DEM raster in GeoTIFF format (.tif) were created using the ground classified lidar points with the hydro-flattened breaklines. The files are delivered in 1000m by 1000m tiles.

Process Step 4

CC ID: 1349294

Description:

The NOAA Office for Coastal Management (OCM) created references to the USGS GeoTiff files that were ingested into the NOAA Digital Coast Data Access Viewer (DAV). No changes were made to the data. The DAV will access the raster data as it resides on Amazon Web Services (AWS).
