The NOAA Office for Coastal Management (OCM) received the GeoTIFF files from New Kent County, Virginia. Sanborn’s standard procedure before every mission is to perform pre-flight checks to ensure correct operation of all systems. All cables were checked, and the sensor head glass was cleaned. A three-minute static session was conducted on the ground with the engines running prior to take-off to establish fine-alignment of the IMU and to resolve GNSS ambiguities. The project acquisition consisted of six (6) missions. During the data collection, the operator recorded information on log sheets which includes weather conditions, lidar operation parameters, flight line statistics and PDOP. Preliminary data processing was performed in the field immediately following the missions for quality control of GNSS data and to ensure sufficient coverage of the project AOI. Any problematic data could then be re-flown immediately as required. Final data processing was completed in the Colorado Springs, CO office. The GNSS/IMU data was post-processed using POSPac software to create Smoothed Best Estimate Trajectory (SBET) file(s). The SBET was then combined with the laser range measurements in Riegl LMS software to produce the 3-dimensional coordinates resulting in an accurate set of Raw Point Cloud (RPC) mass points. These raw swath (*.las) files are output in WGS84, UTM, Ellipsoid, Meters and transformed into the project Coordinate Reference System (CRS) upon ingest into GeoCue before project wide-lidar matching. The Riegl LMS pre-processing software created raw swath files with all return values. This multi-return information was processed and classified to obtain the required features for delivery. All lidar data is processed using the ASPRS binary LAS format version 1.4. Lidar filtering was accomplished using GeoCue with TerraSolid processing and modeling software. The filtering process reclassifies all the data into classes within the point cloud classification scheme. Once the data is classified, the entire dataset is reviewed and manually edited for anomalies that are outside the required guidelines of the product specification or contract requirements. This can include, but is not limited to, classifying bridges, structures, filling culverts, and manually analyzing the bare-earth surface by classifying features that belong in non-extraneous classification codes. 32-bit GeoTIFF (*.tif) elevation rasters were created from the bare-earth points in the processed lidar dataset and hydro-flattened breaklines. Bare-earth rasters were produced with the bilinear interpolation methodology and GDAL v2.4.0 was used to define the CRS. Each pixel contains an elevation. The NOAA Office for Coastal Management (OCM) received 4290 GeoTIFF files from New Kent County. The files were in VA State Plane South NAD83 (HARN) feet coordinates and the elevations were in NAVD88 (GEOID18) feet. The raster files were at a 1 foot grid spacing. The GeoTIFF files were copied to NOAA OCM resources and made available for bulk and custom downloads from the NOAA Digital Coast Data Access Viewer (DAV). 2026-10-21T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor New Kent County, VA GeoTIFF Files New Kent County, VA https://www.newkent-va.us/297/GIS WWW:LINK-1.0-http--link New Kent County GIS Source Citation URL information originator Riegl VQ-1560ii Lidar Sensor The Dual LIDAR Waveform Processing Airborne Scanning System VQ-1560ii provides further increased performance and highest productivity based on a laser pulse repetition rate of up to 4 MHz, resulting in more than 2.66 million measurements per second on the ground.
