Multiple returns were recorded for each laser pulse along with an intensity value for each return. The data acquisition occurred in missions in 2006. The data was collected by Sanborn Mapping Company, Inc. for the Texas Water Development Board (TWDB)and the Federal Emergency Management Agency (FEMA). purpose: This LIDAR operation was designed to provide a high density set of masspoints within the defined areas. The data sets are suitable for the development of contours for use in hydraulic/hydrologic model development, and for assessing environmental impacts. Typical uses for the data set include: FEMA Flood Plain Map Modernization, DFIRM map updates, watersheds and other hydro studies per FEMA specifications, county mapping projects, and flood mitigation assessment. credit: Data collected by Sanborn Mapping Company, Inc. for the Texas Water Development Board (TWDB) and the Federal Emergency Management Agency (FEMA).

It was reviewed by the NOAA Coastal Services Center at the macro level, which includes checking for format and point characteristics for approximately 5% of the tiles. In addition, the entire data set is reviewed to establish that bare earth processing and proper classification of the points has been performed. It does not include accuracy or data processing (e.g. bare earth quality, flightline mismatch, feature removal) assessments. Based on the limited review, the data set on average appeared to be of fair quality. No quantitative accuracy assessment was performed. return to top distributionInfo: (MD_Distribution) distributionFormat: (MD_Format) name: LAZ version: distributor: (MD_Distributor) distributorContact: (CI_ResponsibleParty) organisationName: DOC/NOAA/NOS/CSC > Coastal Services Center, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 843-740-1200 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave. city: Charleston administrativeArea: SC postalCode: 29405-2413 electronicMailAddress: csc.info@noaa.gov role: (CI_RoleCode) distributor distributionOrderProcess: (MD_StandardOrderProcess) orderingInstructions: The National Geophysical Data Center serves as the archive for this LIDAR data.

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. The PDOP and distance separation is as follows: 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. dateTime: DateTime: 2007-08-01T00:00:00 processor: (CI_ResponsibleParty) individualName: Jamie Young organisationName: Sanborn Mapping positionName: LiDAR Manager contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 719-264-5602 facsimile: 719-264-5637 address: (CI_Address) deliveryPoint: 1935 Jamboree Drive city: Colorado Springs administrativeArea: Colorado postalCode: 80920 country: United States electronicMailAddress: jyoung@sanborn.com role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: IMU data Processing: IMU data provides information concerning roll, pitch and yaw of collection platform during collection event.

The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights. dateTime: DateTime: 2006-01-03T00:00:00 processor: (CI_ResponsibleParty) individualName: Pamela Grothe organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) contactInstructions: Contact Data Center role: (CI_RoleCode) processor return to top metadataMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually dateOfNextUpdate: 2014-06-11 maintenanceNote: This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2013-01-04 version of the FGDC RSE to ISO 19115-2 for LiDAR transform. maintenanceNote: Translated from FGDC 2013-06-11T09:44:12.91-06:00 maintenanceNote: Last Metadata Review Date: 2011-11-19 |
