The QL2 requires collection of 2 points per square meter (ppsm), nominal LiDAR pulse spacing of no greater than 0.7 meter for 463 square miles and 4 PPSM for 494 sq. miles and a vertical accuracy of better than 10-cm RMSE. (Merrick will provide data to a 9.25cm vertical accuracy in the interest of meeting a 1 foot contour accuracy specification and this will still meet the QL2 specification). These files contain rasterized topographic lidar elevations at a 3 ft grid spacing. The NOAA Office for Coastal Management (OCM) downloaded this DEM data from the AK DGGS site, processed it, and made it available on the NOAA Digital Coast. In addition to this bare earth digital elevation model (DEM) raster data, lidar point and breakline data are also available. Links to these data are located in the URL section of this metadata record. The breakline data has not been reviewed by OCM and is made available at the user's discretion. purpose: 957 square miles of 2 ppsm and 4 ppsm LiDAR to USGS QL2 specifications to support the Municipality base mapping efforts. credit: Municipality of Anchorage, AK; Merrick & Co; McElhanney 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 contactInstructions: Telephone: 843-740-1202 Email: coastal.info@noaa.gov 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 contactInstructions: Telephone: 843-740-1202 Email: coastal.info@noaa.gov role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) notPlanned graphicOverview: (MD_BrowseGraphic) fileName: https://coast.noaa.gov/htdata/lidar2_z/geoid12b/data/8406/supplemental/ak2015_anchorage_m8406.kmz fileDescription: This graphic displays the footprint for this lidar data set. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION keyword: EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science Keywords date: (missing) edition: 12.3 descriptiveKeywords: (MD_Keywords) keyword: North America > United States of America > Alaska type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) date: (missing) descriptiveKeywords: (MD_Keywords) keyword: DEM keyword: Light Detection and Ranging type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: 2015 type: (MD_KeywordTypeCode) temporal descriptiveKeywords: (MD_Keywords) keyword: DEMs - 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]: 2015 Lidar DEM: Municipality of Anchorage, AK [Data Date Range], https://www.fisheries.noaa.gov/inport/item/50332. 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 flightlines are compared to evaluate both their relative and absolute accuracies. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: LIDAR data was collected using McElhanney's ALS70 HP LIDAR sensor. The raw data was verified in MARS software for complete coverage of the project area, and boresighted to align the flightlines. Raw data files were parsed into manageable client-specific tiles. These tiles were then processed through automated filtering that separates the data into different classification groups: unclassified points, ground points, low points, water, ignored ground, Bridge Decks and Culverts. The data was next taken into MARS to reclassify the erroneous points that may remain in the LIDAR point cloud after auto filter. dateTime: DateTime: 2016-11-29T00:00:00 processStep: (LI_ProcessStep) description: Using MARS software ESRI float grid files (.flt/.hdr) files are created with a one meter cell size. The ground classified LIDAR points plus the hydro breaklines are used to create these files. The breaklines are rivers greater than 30m wide and waterbodies larger than 2 square acres in size. The .flt files are imported to Erdas Imagine (.img) files. The tiles are delivered in 1000m by 1000m tiles. dateTime: DateTime: 2016-11-29T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) downloaded the Anchorage 2015 DTM grid data from the Alaska Division of Geological & Geophysical Surveys (DGGS) Elevation Portal (http://elevation.alaska.gov/#64.99794:-155.47852:4) in October 2017. The raster files were in .img format and AK State Plane Zone 4, NAD83, feet coordinates. The elevations were in NAVD88 ft. The grid spacing was 3 ft. OCM did the following processing to the data for Digital Coast storage and provisioning purposes: 1. Converted to cloud optimized GeoTiff format and GeoTiff format 1.1 for georeferencing purposes. dateTime: DateTime: 2023-06-26T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: DTM date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: (inapplicable) contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: http://elevation.alaska.gov/#64.99794:-155.47852:4 protocol: WWW:LINK-1.0-http--link name: Source Citation URL description: Source Citation URL function: (CI_OnLineFunctionCode) information role: (inapplicable) source: (LI_Source) sourceCitation: (CI_Citation) title: Ground Control date: (CI_Date) date: 2015-01-01 dateType: (CI_DateTypeCode) publication sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimeInstant: timePosition: 2015 source: (LI_Source) sourceCitation: (CI_Citation) title: Lidar date: (CI_Date) date: 2016-11-29 dateType: (CI_DateTypeCode) publication sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimePeriod: beginPosition: 2015-05-10 endPosition: 2016-09-29 | |
