Lidar data will serve multiple purposes, but has primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. This dataset is an index used as a reference frame for the lidar delivery area. Purpose: Provide an index illustrating the spatial location of raster image files. Supplemental_Information: This metadata file has been written to document and describe the location of all the raster files generated for this project. The DGGS metadata standard extends the FGDC standard to also include several elements that are required to facilitate our internal data management. These elements relate individual data items to a common dataset. This dataset describes a single layer titled: >raster-index: raster index used as a reference frame for lidar delivery area Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 2010 Ending_Date: 2011 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: As needed Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -150.82 East_Bounding_Coordinate: -141.00 North_Bounding_Coordinate: 70.38 South_Bounding_Coordinate: 61.04 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Theme_Keyword: Alaska Pipeline Theme_Keyword: Gasline Theme_Keyword: Geomorphology Theme_Keyword: Lidar Theme_Keyword: Proposed Natural Gas Pipeline Theme_Keyword: Raster Index Shapefile Place: Place_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Place_Keyword: Alaska Highway Corridor Place_Keyword: Alaska, State of Place_Keyword: Trans-Alaska Pipeline Access_Constraints: This dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Lidar data were collected and processed by Watershed Sciences, Inc. of Corvallis, OR. Survey data were collected by McClintock Land Associates of Eagle River, AK. Lidar data and derivative products were checked for quality, completeness, and accuracy by State of Oregon Department of Geology & Mineral Industries based in Portland, OR. Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcGIS 10.0.0.2414 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Individual polygons within the vector shapefile, referred to as tiles, are used to designate raster data files. Tiles were created by Watershed Sciences, Inc. in consultation with DGGS and are referenced to 1:63360 USGS quadrangles with the exception of the Talkeetna Mts and Phillip Smith Mts quadrangles where Mts has been replaced with MTNS. Attribute values have been visually inspected to ensure accuracy. Logical_Consistency_Report: Data was visually inspected in ArcGIS to ensure consistency. Completeness_Report: Lidar data was checked for accuracy and completeness. Please refer to the lidar QC report and overview report for details about the raster index file. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Data was visually inspected to ensure horizontal positional accuracy. Lineage: Process_Step: Process_Description: A vector shapefile was created as an index to show the organization of lidar raster files. USGS 1:63360 quadrangles were used as a basis for creating the index so that individual tiles fall within only one quadrangle. In some instances, quadrangles contain multiple tiles in order to minimize file size of the indexed raser files. Process_Date: 2010, 2011, 2012 Process_Step: Process_Description: Raster index shapefiles from individual deliveries were combined into a single shapefile. During this process the data were reprojected into Alaska Albers Equal Area Conic. Process_Date: 2012 Process_Step: Process_Description: A metadata file was created to describe the raster index file.
