The 142 square miles includes the communities of Westport, Dartmouth, New Bedford, Fairhaven, Mattapoisett, Marion, and Wareham. The project area was defined using a buffered shapefile with limits along the coastline. The project area included a portion of both counties. All lidar data was acquired during November 2006 by Sanborn. Orthophotography used to create 2D breaklines was produced in 2005 by MassGIS as part of its statewide orthophoto program. All lidar data that was acquired was produced in accordance with FEMA specifications (Source: FEMA Guidelines and Specifications, Appendix N, Section N.1.2). Lidar Acquisition Parametes: Average Altitude: 1,200 Meters AGL Airspeed: ~120 Knots Scan Frequency: 36 Hertz Scan Width Half Angle: 16 Degrees Pulse Rate: 50000 Hertz The data being distributed through the NOAA Digital Coast are Gridded Bare-Earth LAS files. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: The LIDAR derived data sets, including the first and last returns, a Gridded DEM, TIN file, 2' contours in ESRI geodatbase format and masspoint and Breakline files were developed to support Camp Dresser and McKee's continued development of updated Digital Flood Insurance Rate Maps and flood insurance studies for coastal areas in Massachusetts. Contours are based on bare earth LIDAR and breaklines digitized from 2D orthophotography (subsequently draped over the 3D LIDAR points) (Source: FEMA Guidelines and Specs, Appendix N). Coastal shoreline areas were set a 0.00 elevation to cartographically represent contours. 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 graphicOverview: (MD_BrowseGraphic) fileName: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/2602/supplemental/ma2006_fema_bristolplymouth.KMZ fileDescription: This graphic shows the lidar coverage for the communities of Westport, Dartmouth, New Bedford, Fairhaven, Mattapoisett, Marion, and Wareham. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: Breaklines keyword: Contours keyword: DEM keyword: Digital Terrain Model keyword: Elevation Data keyword: Flow vectors keyword: LIDAR keyword: Land Surface keyword: Relief keyword: Slope keyword: Topography type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: FEMA NFIP Topic Category date: (missing) 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]: 2006 Federal Emergency Management Agency (FEMA) Topographic Lidar: Bristol and Plymouth Counties, Massachusetts [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49770. 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 category classes of bare earth, low grass and urban were used. For the Bristol checkpoints, the RMSEz is 14.7 centimeters. This area yielded much better results than the project requirement of 18.5 centimeters RMSEz. The vertial accuracy of the source data meet or exceed vertical National Map Accuracy Standards for 2-foot contour mapping. Please set the Project Report located in the supplemental information section above for more details. ; Quantitative Value: 0.294 meters, Test that produced the value: This value reflects the data's tested Vertical Root Mean Squared Error (RMSEz) at 95% confidence interval (RMSEz @ 95% confidence = RMSEz x 1.9600) as defined by the Federal NSSDA (National Spatial Standard for Data Accuracy).

New aerial stereo photography was flown, and aerial triangulated to allow production of breakline ehnacement of the Bare earth DEM and to hydrologically enforce contours and elevation data through the compilation of drainage breaklines. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: Using an Optech Light Detection and Ranging (LiDAR) system, flight lines were planned for standard density 1.4 meter GSD. The Flight plan for the project includes the following specifications to fully meet the project requirements - single pass density of approximately 2.0 square meters per sample * Swath width 728 meters * Flight altitude 1000 meters * flight line spacing -589 meters with 125 meters overlap *Scan Frequency- 35 Hz *Scan Angle- 20 degrees * Aircraft ground speed -- 140 knots * System Calibration pre and post mission * Two GPS base stations within 30 KM. Multiple returns were recorded for each laser pulse along with an intensity value for each return. The data are calibrated for geographic referencing. Points are further processed, using TerraSolid software, to classify return values. The first and last return data is filtered to remove the vegetation and above ground manmade features to yield a ground surface. The bare earth elevation data was draped over the existing orthophotos. Breaklines for hydrographic features, bridges, culverts and major roadways were captured in 2D. Elevations were associated to the breaklines by draping onto the Lidar data. The DTM was then used to produce a TIN. The TIN was used to generate 2-ft contours. dateTime: DateTime: 2006-12-31T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received topographic files in ASCII format. The files contained lidar elevation measurements. The data were received in Massachusetts State Plane Mainland (Zone 2001), NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The ASCII files were converted to LAS V1.2 using LASTools' txt2las. 2. The topographic las file '8002645' was found to be corrupt and removed from the data set. 3. All points in the topographic las files were converted to Class 2 (Ground) using LASTools' las2las. 4. The topographic las files were found to contain noise, those points were manually reclassified to Class 7 (Noise) using Merrick MARS7. 5. All additional VLRs in the topographic las files' header used by MARS7 were removed using LASTools' las2las. 6. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03. 7. The topographic las files were converted from a Projected Coordinate System (MA SP 2001) to a Geographic Coordinate System (NAD83). 8. The topographic las files' horizontal units were converted from feet to decimal degrees. 9. The topographic las files' vertical units were converted from feet to meters. dateTime: DateTime: 2013-11-01T00:00:00 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: 2023-07-01T06:28:24 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
