The goal of the NGOM LiDAR project in the post-Katrina environment is to provide scientific knowledge and tools required to make optimal decisions about land resource use, management practices, and future development in the northern Gulf of Mexico coastal zone. This regional LiDAR elevation mapping data will be used for modeling, predicting landscape change, promoting restoration of ecosystems, and mitigating risks associated with anthropomorphic and natural hazards. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section. Classified LAS files are used to show the manually reviewed bare earth surface. Any additional classification is provided via automated macro functionality from proprietary Photo Science TerraScan macros. These additional classifications include Class 4 - Medium Vegetation and Class 5 - High Vegeation. This allows the user to create Intensity Images, Break Lines, Raster DEM, and Triangular Irregular Networks. Photo Science, Inc. flew the LiDAR and processed the data.

Vertical Positional Accuracy Classified LAS files were tested by Photo Science for both vertical and horizontal accuracy. All data is seamless from one tile to the next, no gaps or no data areas. The vertical unit of the data file is in decimal feet with 2-decimal point precision. ; Quantitative Value: 0.0013 meters, Test that produced the value: RMSE in meters Completeness Report Datasets contain complete coverage of tiles. Conceptual Consistency Classified LAS files were tested by Photo Science for both vertical and horizontal accuracy. All data is seamless from one tile to the next, no gaps or no data areas. Applanix software was used in the post processing of the airborne GPS and inertial data that is critical to the positioning and orientation of the sensor during all flights. POSPac MMS provides the smoothed best estimate of trajectory (SBET) that is necessary for Optech's post processor to develop the point cloud from the LiDAR missions. The point cloud is the mathematical three dimensional collection of all returns from all laser pulses as determined from the aerial mission. At this point this data is ready for analysis, classification, and filtering to generate a bare earth surface model in which the above ground features are removed from the data set. The point cloud was manipulated within the Optech software; GeoCue, TerraScan, and TerraModeler software was used for the automated data classification, manual cleanup, and bare earth generation from this data. Project specific macros were used to classify the ground and to remove the side overlap between parallel flight lines. All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler. All Class 2 LiDAR data inside of the collected breaklines were then classified to Class 9 using TerraScan macro functionality. A buffer of 1 meter was also used around each hydro flattened feature. The breakline files were then translated to ESRI Shapefile format using ESRI conversion tools. Data was then run through additional macros to ensure deliverable classification levels matching LAS ASPRS Classification structure. GeoCue functionality was then used to ensure correct LAS Version. In house software was used as a final QA/QC check to provide LAS Analysis of the delivered tiles. 2010-01-01T00:00:00 The NOAA Office for Coastal Management (OCM) received topographic files in LAS format. The files contained lidar elevation and intensity measurements. The data were received in UTM Zone 16 (NAD83) coordinates and were vertically referenced to NAVD88 using the Geoid09 model. The vertical units of the data were meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid09. 2. The horizontal coordinate system was converted from UTM (meters) to Geographic (decimal degrees). 2012-12-01T00:00:00 Source Contribution: LiDAR points were used to produce the deliverables. | Source Geospatial Form: digital data | Type of Source Media: hard drive LiDAR 2010-01-01 publication 2010-02-20 2010-04-28 The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2025-04-07NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
