Conceptual Consistency Data covers the entire area specified for this project. The NOAA Office for Coastal Management (OCM) ingested references to the USGS GeoTiff files that are hosted on Amazon Web Services (AWS), into the Digital Coast Data Access Viewer (DAV). The DAV accesses the raster data as it resides on AWS . 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). 2023-11-28T00:00:00 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. 2023-11-28T00:00:00 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. 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).
