(TMSI) for the Chemung Watershed and broken down into two AOIs based on the level of processing performed on the dataset. AOI-1 covers approximately 709 square miles, which is the full extent of the acquisition boundary plus a 100-meter buffer around the perimeter of this boundary. AOI-1 was delivered as full-swath, calibrated, and boresighted flight lines in LAS format. A subset of AOI-1, delineated by a buffer around the major stream networks, covers approximately 308 square miles. RAMPP will make the following products available to FEMA by uploading the digital data to the MIP, where applicable, or via hard drives. The deliverables for this Technical Support Data Notebook (TSDN) submittal include written certification that the topographic data development meets minimum Federal Emergency Management Agency (FEMA) standards and specifications. In cases where data do not meet the required standards and specifications, an explanation is included. Additionally, the related metadata file has been uploaded to the Mapping Information Platform (MIP). Deliverables will include raw point clouds and classified point clouds (see report for details), hydro-lines, low confidence polygons, qa/qc report, survey report and a summary report. Classifications include ASPRS Class 1,2,7,9,11. Acquisition AOI-2 fulfills this dataset (see Page 3 of the Final Topographic Data Developmental Report). This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: The following is the Risk Assessment, Mapping, and Planning Partners (RAMPP) Scope of Work for Task Order HSFEHQ-10-J-0006 for Chemung Watershed, NY. RAMPP acquired and processed LiDAR data to support flood hazard data updates based on the FEMA ordering Sheet, dated June 29, 2010. The acquired elevation data complies with the FEMA Procedures Memorandum: Standards for LiDAR and other High Quality Elevation Data (version dated July 19, 2010). RAMPP will be responsible for full turnkey implementation of the elevation collection, processing and post processing of the LiDAR data, checkpoint surveys, quality assurance and quality control (QA/QC). Upon completion of topographic data collection and processing, RAMPP will submit a detailed description of the data available and include the source input files used in a TSDN report document and upload the digital data to the MIP where applicable. Additionally, RAMPP will submit a hard drive to the FEMA Engineering Library with all the LiDAR data and the appropriate reports and documents. 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) notPlanned graphicOverview: (MD_BrowseGraphic) fileName: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/5029/supplemental/ny2011_fema_chemung_watershed_m5029.kmz fileDescription: This graphic shows the lidar coverage for the 2011 FEMA Chemung Watershed AOI-2 project in New York state. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: Land Surface type: (MD_KeywordTypeCode) theme 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 FEMA Lidar: Chemung Watershed (NY) (AOI 2) [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49887. 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.

AOI-1 covers approximately 709 square miles, which is the full extent of the acquisition boundary plus a 100-meter buffer around the perimeter of this boundary. AOI-1 was delivered as full-swath, calibrated, and boresighted flight lines in LAS format. A subset of AOI-1, delineated by a buffer around the major stream networks, covers approximately 308 square miles. This dataset (AOI-2) was processed by TMSI to classify bare-earth ground points and hydro features and was delivered as a tiled, classified, point cloud in LAS format using the following classification scheme: Class 1 - Processed but unclassified Class 2 - Bare-earth ground Class 7 - Low points and noise Class 9 - Water Class 11 - Withheld dateTime: DateTime: 2011-05-01T00:00:00 processStep: (LI_ProcessStep) description: Processing Processing of the LiDAR data begins with refinement of the initial boresight alignment parameter in the ALS Processor configuration file (.reg) delivered with the raw data. For projects that have more than one lift, the boresight for each lift has to be completed individually because it may differ slightly from lift to lift. Lift boresighting is accomplished using the tri-directional calibration flight lines over the project area. One calibration flight line is flown bi-directionally overlapping a project flight line within the lift. This bi-directional calibration will also be used as a parallel flight line with the adjacent flight line. There is a cross flight line collected perpendicular to both. All three lines along with the parallel project flight line are examined to ensure that they agree, within expected system tolerances, in the overlapping areas. The two bi-directional flight lines are used to diagnose Roll and Pitch. The two parallel flight lines are used to diagnose and correct Heading error. The two perpendicularly overlapping flight lines are used to examine Variable Scan Angle error. To begin lift boresight, the raw LiDAR data of the calibration flight lines will be processed with the initial boresight parameters determined from the LiDAR Sensor Calibration. Once the boresighting is done for the calibration flight lines, the adjusted settings will be applied to the complete lift and checked for consistency. For a well-maintained LiDAR system, functioning correctly under normal operating conditions, actual boresight angles can be considered constant throughout a single mission. Therefore, once the boresight angles have been adjusted based on the calibration flight lines, the same corrections can be applied to the entire lift. Under optimal circumstances, the boresight parameters determined for the calibration flight lines should be the same for all flight lines in the lift, but residual errors can occur. To correct for this, all of the overlaps between flight lines (side lap) and intersections of the project cross flight lines should be examined for internal consistency. If the results of the boresights start showing drift in the middle of the lift or the misalignment between flight lines starts exceeding project accuracy specifications, boresight parameters need to be adjusted to correct these errors. Once boresight adjustments are completed for each individual lift, the technician checks and corrects the vertical misalignment of all the flight lines and also the matching between data and ground truth. This process includes calculating the zbias value for each flight line so that all flight lines are vertically aligned and the entire data set match to the ground control points within the project specified accuracy range. The technician will run a final vertical accuracy check after the z correction. The result will be analyzed against the project specified accuracy to verify it meets the requirement. dateTime: DateTime: 2011-07-01T00:00:00 processStep: (LI_ProcessStep) description: Quality Risk Assessment, Mapping, and Planning Partners (RAMPP) performed a limited review of the Chemung Watershed, New York dataset. 100% of the data was checked for completeness and 5% of the data was visually examined at the micro level for qualitative issues according to the scope of work. A vertical accuracy assessment was performed on the first return points in the Level 1-processed dataset (AOI-1) and the full point cloud in the Level 2-processed dataset (AOI-2). No major completeness or quality issues were identified. Both datasets meet the Federal Emergency Management Agency's (FEMA) vertical accuracy specifications. Based on the limited qualitative and vertical accuracy assessments conducted by RAMPP on the data delivered, the Chemung Watershed, NY delivery meets the applicable project specifications as set forth by the IDIQ Subcontract # HSFEHQ-09-D- 0369-U005, Task Order HSFEHQ-10-J-0006, revised September 3, 2010. dateTime: DateTime: 2011-07-01T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received AOI 2 of the Chemung Watershed project boundary. The dataset included topographic LAS files as part of a FEMA data delivery. The files contained lidar easting, northing, elevation, as well as ancillary collection attributes. The data were received in UTM 18 (meters) and were vertically referenced to NAVD88 using the "latest" geoid, which was assumed to be the Geoid09 model due to the provided collection dates (as GPS times were usable for this determination). OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The LAS files were converted from feet to meters, removing erroneous elevations. 2. The LAS files were converted from orthometric (NAVD88) heights to ellipsoidal heights using the Geoid09 model but remaining in meters. 3. The LAS files were converted from a Projected Coordinate System to a Geographic Coordinate system with decimal degree units. dateTime: DateTime: 2016-06-14T00:00:00 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: 2023-07-01T07:33:17 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
