Abstract:
Authorized Oil and Gas Leases within the National Petroleum Reserve - Alaska
Includes 1999, 2002, 2004, 2006, 2008, 2010, 2011, 2012 Lease Sale Tracts.
Purpose:
Authorized oil and gas leases layer provides a graphic display of the oil and gas leases from the 1999, 2002, 2004, 2006, 2008 segregations of the 1999 leases, 2008, 2010, 2011, 2012 lease sales.
Provides a graphic display of the authorized oil and gas leases for planning, mapping, calculating acreage, as well as for visual inspection of the authorized leases.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes were cross-tablulated against source Alaska Land Information System tables. Any errors or omissions were tracted back to source and corrected in the source data. Final results are a one-to-one representation of the source data.
Logical_Consistency_Report: Polygon topology exists.
Completeness_Report: Dataset is complete and verified.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal accuracy of proposed lease sale based on protracted section grid and the boundary of the NPRA
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 1
Horizontal_Positional_Accuracy_Explanation:
Protracted section grid is stored as GCS NAD83 coordinates. Protracted section grid projected from geographic coordinates to Alaska Albers Equal Area Conic NAD83 coordinates. While leases based on protracted positions, the positional assessment of the leases are at least within 1 meter of protracted section/township positions.

Process_Step:
Process_Description:
1. Queried township/section, case serial number, case status, geoname, and year from Alaska Land Information System database. 2. Created definition query using ArcMap to eliminate protracted sections that were not authorized oil and gas leases in NPRA. 3. Dissolved leases by case serial number, geoname, and year. 4. Clipped dissolved layer using the NPRA Boundary.
