Title: National Petroleum Reserve Alaska Boundary (Arcs) NAD83
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
The NPRA Boundary (arcs) are a composite of 5 sets of arcs. Each arc is attributed with the data source of the arc.
Purpose: Arcs used to create the NPRA (polygon) Boundary.
Supplemental_Information:
1. Spatial Data Management System bearings and distances for NPRA - 1876 arcs
2. High, High Water Line within USS 9571 - one arc
3. Connecting Line Between MC2, T11N, R39W and the point of intersection of the administrative lease line of the N.P.R.A. and the surveyed W. bdy. of the N.P.R.A. - one arc
4. Southern boundary of the N.P.R.A. from a point in unsurveyed township Sec19, T31N, R13E, KRM northeasterly along the Continental Divide to Closing Corner 1, T11S, R43W, UM - one arc
5. Final Administrative Lease Line of the National Petroleum Reserve - Alaska (administrative lease line) - one arc made up of 8011 points of Latitude and Longitude
