Title:
National Petroleum Reserve Alaska - Administrative Coastal Boundary Points (NAD83)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
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.
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.
The ASCII character ` (hex 60) represents the degree symbol.
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.
Supplemental_Information:
The source information for the latitudes, longitudes, and comments comes from the manuscript entitled, "FedReg NPRA text bndy continuous with ASCII symbol.doc"
This manuscript was produced on 30 MAY, 2003.

Process_Step:
Process_Description:
1. Save source document as ASCII text file. 2. Remove blank lines and extraneous text lines at beginning and end of file. 3. Use copy and paste to format text file as Lat, Long, Comment fields. 4. Used AWK script to parse source manuscript text file: #!/bin/ksh # Tim Varner 20071022 # parse_npra.txt # Based on an input file of dms coordinates below: #Lat. 70`22'30.10583" N.|Long. 151`07'49.61180" W.|Beginning at the most southwesterly point of the N.P.R.A. in sec. 21 shown on the plat of T. 12 N., R. 4 E., accepted May 31, 1994 #Lat. 70`22'27.99466" N.|Long. 151`07'54.91558" W.|Angle points along a portion of the administrative coastal bdy. of the N.P.R.A. in surveyed T. 12 N., R. 4 E. # Put parse_npra.awk somewhere in your PATH # CAN BE OUTPUT TO A FILE... # AT THE COMMAND LINE TYPE: # gawk -f parse_npra.awk (file containing dms coordinates) > (new file of dd coords) # # CAN BE OUTPUT TO THE SCREEN... # AT THE COMMAND LINE TYPE: # gawk -f parse_npra.awk (file containing dms coordinates) { FS = "|" OFS = "|" dmslat = $1 dmslon = $2 comment = $3
latdd = (substr($0,6,2)) latmm = (substr($0,9,2)/60) latss = (substr($0,12,8)/3600) lat = latdd + latmm + latss latdec = sprintf("%16.14f", lat)
londd = (substr($0,31,3)) lonmm = (substr($0,35,2)/60) lonss = (substr($0,38,8)/3600) lon = londd + lonmm + lonss
londir = (substr($0,48,1)) if (londir = "W") londec1 = (lon * (-1)) else londec1 = lon
londec = sprintf("%17.14f", londec1)
shp = "2 point ("londec " " latdec")"
print NR, NR, dmslat, dmslon, comment, latdec, londec, shp "|"
5. Once text file is parsed using parse_npra.awk script, resulting load file is used to load into new empty database table.
CREATE TABLE npra_admin_coastal_points ( objectid INTEGER NOT NULL, corner_number INTEGER NOT NULL, dms_latitude VARCHAR(30), dms_longitude VARCHAR(30), comment VARCHAR(255), dd_latitude DECIMAL, dd_longitude DECIMAL, shape ST_Point )
6. Load file was loaded into the database table, "npra_admin_coastal_points." 7. Comments were inserted into table to reflect table values for lines without comments. Comments were copied from last known comment for each row up to next not null comment. Database table was compared line by line to source manuscript.
