Title:
National Petroleum Reserve Alaska Administrative Lease Line (NAD83)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
The NPRA Administrative Coastal Boundary dataset is a continuous, point to point listing of all angle points for the Final Administrative Lease Line of the National Petroleum Reserve - Alaska (administrative lease line). The listing runs from east to west.
All Public Land Survey System references are for the Umiat Meridian, Alaska.
N.P.R.A. refers to National Petroleum Reserve - Alaska.
No angle points for the administrative lease line of the N.P.R.A. fall in the interior of T. 17 N., R. 26 W., and T. 22 N., R. 18 W.
All latitudes and longitudes are on the North American Datum 1927.
Purpose:
This dataset was created as a spatial representation of the angle points the NPRA Final Administrative Lease Line and points of intersection with the Public Land Survey System and the NPRA Final Administrative Lease Line.

Process_Description:
Loaded formated point data from table provided by Frank Hardt - BLM Cadastral Land Surveyor of points from Federal Register for the NPRA Administrative Coastal Boundary Points dataset is a continuous, point to point listing of all angle points for the Final Administrative Lease Line of the National Petroleum Reserve - Alaska (administrative lease line). The listing runs from east to west.
The query below was created as a stored procedure in Informix which populates the line strings from paris of points.
--linecoord_npra.sql create procedure linecoord_npra() define x1, y1, x2, y2 float; define bcor, ecor, obj_id, nbr_rows, i integer; -- process each line let nbr_rows = (select max(objectid) from npra_admin_coastal_points) - 1 ; let obj_id = 0; while obj_id < nbr_rows begin let bcor = obj_id + 1; let ecor = bcor + 1; select dd_longitude, dd_latitude into x1,y1 from npra_ad min_coastal_points where objectid = bcor; select dd_longitude, dd_latitude into x2,y2 from npra_ad min_coastal_points where objectid = ecor; let obj_id = obj_id + 1; insert into npra_admin_coastal_bndy (objectid, shape) va lues ( obj_id, ('2 LINESTRING (' || x1 || ' ' || y1 || ', ' || x2 || ' ' || y2 || ')')); end end while; end procedure;
8011 points created 8010 individual linestrings.
