Terrain data requirements allow for flexibility in the types of information provided as sources used to produce final terrain deliverables. Once this type of data is provided, FEMA will be able to account for the origins of the flood study elevation data. (Source: FEMA Guidelines and Specifications, Appendix N, Section N.1.2). Reflective surface data represents the DEM created by laser energy reflected from the first surface encountered by the laser pulse. Some energy may continue beyond this initial surface to be reflected by a subsequent surface as represented by the Last Return data. Intensity information is captured from the Reflective Surface pulse and indicates the relative energy returned to the sensor as compared to the energy transmitted. The Intensity image is not calibrated or normalized but indicates differences in energy absorption due to the interaction of the surface materials with laser energy at the wavelength transmitted by the sensor. 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. LIDAR data is used for 3D visualization, elevation based analysis and for feature extraction.

Vertical Positional Accuracy LiDAR data accuracy determination shall employ the National Standard for Spatial Data Accuracy (NSSDA). Contracted to meet 18.5cm (RMSE) on open bare terrain and 37.0cm for obscured areas. Completeness Report LIDAR raster data is visually inspected for completeness to ensure that any gaps between flight lines or loss of signal represents less than 5% of required collection area. LIDAR is self-illuminating and has minimal cloud penetration capability. Water vapor in steam plumes or particulates in smoke may cause reflection of LIDAR signals and loss of elevation information beneath these plumes. Glass structures and roofs may appear transparent to the LIDAR signal and therefore may not register on the reflective surface. Some asphalt formulations have been shown to absorb topographic LIDAR wavelength energy resulting in "pitting" of roof surfaces using this material. Conceptual Consistency All LAS formatted LIDAR data are validated using commercial GIS software to ensure proper formatting and loading before delivery. This validation procedure ensures that data on delivery media is in correct physical format and is readable. Data Collection: Using an Leica Geosystems ALS50 Laser Systems, 89 flight lines with a nominal point spacing = 1.4 meters (4.59 feet) were collected over Erie County, NY (approximately 1044 square miles). Multiple returns were recorded for each laser pulse along with an intensity value for each return. The data acquisition occurred in missions on April 17, 2008 and April 28, 2008. During the LIDAR campaign, the field crew conducted a GPS field survey to establish final coordinates of the ground base stations for final processing of the base-remote GPS solutions. 2008-09-01T00:00:00 Airborne GPS Processing: 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 overlap between flight lines was removed to provide a homogeneous coverage, and the coverage was classified to extract a bare earth digital elevation model (DEM). Airborne GPS is differentially processed using the GrafNAV V7.50 software by Waypoint Consulting of Calgary, Alberta, Canada. IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario, Canada. The reflective surface is derived using the ALS Post Processor software by Leica Geosystems GIS & Mapping Division of Atlanta, Georgia. The classification and quality control (QC) of LiDAR data is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland. 2008-09-01T00:00:00 LIDAR Ground Point Classification: The classification and quality control (QC) of LiDAR Ground point class is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland. In the filtering process points are classified as Ground or non-Ground classes (Unclassified). 2008-10-01T00:00:00 Output: LAS Files LIDAR points in 1.0 format; ASCII (e,n,z,i) for first return and last return; ESRI GRID for Bare Earth; GeoTiff (8-bit, single band) Intensity Images. 2008-10-01T00:00:00 The NOAA Office for Coastal Management (OCM) received the files in a shapefile as points with a z value associated as elevation, referenced to a Universal Transverse Mercator cooridinate system, zone 16 N in meters and referenced to the NAVD88 Geoid 03 vertical datum with vertical units of measure of meters. OCM performed the following processing to the data to make it available within the Digital Coast: 1. Converted from UTM coordinates to geographic coordinates in decimal degrees. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03. 3. The data were filtered to remove outliers. 4. Provided metadata referenced a 5 and 10 m DEM product therefore metadata intricacies were derived from similar project metadata and an in-depth search for relevant 2008 project information. 2016-06-09T00:00:00 Source Contribution: Raw spatial elevation information | Type of Source Media: Hard drive LiDAR 2008-01-01 publication 2008 The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2025-06-21NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
