LiDAR data, and derivative products produced in compliance with this task order are part of the data to be obtained under the American Recovery and Reinvestment Act (ARRA) of 2009. Contract number G10PC00025. Specifications listed below are based on the U.S. Geological Survey National Geospatial Program Base LiDAR Specification, Version 13. Tile names were slightly altered to meet particular naming conventions on NOAA OCM ftp. Dataset is titled 2010 but due to acquisition dates falling in 2011, the name has been updated. Original contact information: Contact Name: Patrick Emmett Contact Org: USGS Title: USGS NGTOC Phone: 573-308-3587 Email: pemmett@usgs.gov This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: USGS has a requirement for LiDAR data over a portion of Willacy County in Texas, covering approximately 501 square miles. Willacy County is to be collected at a nominal pulse spacing (NPS) of 2.0 meters. The Willacy County Texas LiDAR Acquisition project is to provide high accuracy bare-earth processed LiDAR data suitable for the project area. The project consisted of acquisition, post-processing, classification of LiDAR data, and creation of final deliverable products. All areas shall be collected at a nominal pulse spacing (NPS) of 2.0 meters based on UTM14, related to the North American Datum of 1983 (NSRS2007). Vertical accuracy was to achieve a RMSE Z of 12.5 cm (95% confidence level of less than 24.5 cm) or better in the "Open Terrain" land cover category for all areas. Accuracy statement is based on areas of moderate to flat terrain. Diminished accuracies are to be expected in areas in dense vegetation. The accuracy of the LiDAR data as tested met or exceeded the vertical accuracy requirements, however, derived products may be less accurate in areas of dense vegetation due to a lesser number of points defining the bare-earth in such areas. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded descriptiveKeywords: (MD_Keywords) keyword: Lidar - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_LegalConstraints) useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: Cite As: OCM Partners, [Date of Access]: 2011 ARRA Lidar: Willacy County (TX) [Data Date Range], https://www.fisheries.noaa.gov/inport/item/50048. resourceConstraints: (MD_Constraints) useLimitation: NOAA provides no warranty, nor accepts any liability occurring from any incomplete, incorrect, or misleading data, or from any incorrect, incomplete, or misleading use of the data.

The LiDAR system includes a differential GPS unit and inertial measurement system to provide superior positional accuracy. Acquisition parameters: 1. Flight Height - 2500 meters above mean terrain 2. Swath Width - 34 degrees 3. Sidelap - 30% 4. Nominal Post Spacing - 1.5 meters GPS and IMU processing parameters: 1. Maximum baseline length - Not greater than 40 kilometers. 2. Number of base stations during LiDAR collection - A minimum of 1. 3. Maximum positional RMS of trajectory during LiDAR collection - 0.05 meters 4. IMU processing monitored for consistency and smoothness - Yes. Point Cloud Processing: 1. Horizontal Datum - NAD83(NSRS2007) 2. Horizontal Coordinates - Universal Transverse Mercator, Zone 14, in meters. 3. Vertical Datum - NAVD88 4. Geoid Model used to reduce satellite derived elevations to orthometric heights - NGS Geoid09. LiDAR Processing: 1. Point Cloud data is imported via TerraScan in a Microstation V8 (V) CAD environment on a specified 1500 meter by 1500 meter tiling scheme. 2. Analyze the data for overall completeness and consistency. This is to ensure that there are no voids or anomalies in the data collection. 3. Inspect for calibration errors in the dataset using the TerraMatch software. This is accomplished by sampling the data collected across all flight lines and classify the individual lines to ground. The software will use the ground-classified points by flightline to compute corrections (Heading, Pitch, Roll, and Scale). 4. Orientation corrections (i.e. Calibration corrections) are applied (if needed) to the entire dataset. 5. Automatic ground classification is performed using algorithms with customized parameters to best fit the project area. Several areas of varying relief and planimetric features were inspected to verify the final ground surface. 6. AeroMetric, Inc. provided Quality Assurance and Quality Control (QA/QC) data for this project. AeroMetric captured QA/QC points in 'open terrain' land cover category that were used to test the accuracy of the LiDAR ground surface. TerraScan's Output Control Report (OCR) was used to compare the QA/QC data to the LiDAR data. This routine searches the LiDAR dataset by X and Y coordinate, finds the closest LiDAR point and compares the vertical (Z) values to the known data collected in the field. Based on the QA/QC data, a bias adjustment was determined, and the results were applied (if necessary) to the LiDAR data. A final OCR was performed with a resulting RMSE of 0.088 meters for the project. 7. Each tile is reviewed for accuracy and consistency of the macro ground classification. 8. Once the automatic processing and the testing of LiDAR is complete, AeroMetric meticulously reviews the generated bare-earth surface data to ensure that proper classification was achieved as part of a Quality Control process. 9. Final deliverables are generated and output to a client specified 1500 meters by 1500 meters tiling scheme. dateTime: DateTime: 2011-09-09T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) downloaded topographic files (point clouds) in LAZ format from an USGS ftp site. The data was received in UTM Zone 14 North (in meters) and vertical coordinates were referenced to NAVD88 in meters using the Geoid09 model. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The All-Return LAZ files were checked for erroneous outliers removed. 2. The LAZ files were converted from a UTM coordinates to Geographic Coordinates (decimal degrees), then converted to ellipsoidal vertical units in meters with respect to the Geoid09. 3. Overlapping tiles (42) exist on the county boundary between Hidalgo and Willacy counties. These were decidedly left as is in order to extend past county boundaries for individual county requests. These are duplicate points between projects as they are the same acquired lidar points. dateTime: DateTime: 2015-12-20T00:00:00 processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey. Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org) Processing notes: dateTime: DateTime: 2023-07-01T07:25:46 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
