Quadrangle Control Network (Click on quadrangle control diagram to see full control network)

THURSTON ISLAND - JONES MOUNTAIN CONTROL

1968-69 Season

Engineers: Klaus Anderson, Frederick Brownsworth, Jr., Karl Eissinger, Charles Morrison, and Ronald Todd

Terrestrial survey network employing Wild T-2 theodolite for angular measurements and Electro-tapes for distance measurements.

DKM-3A used for astro measurements.

HUDSON MOUNTAINS CONTROL

1960-61 Season

Engineer: Peter F. Bermel

Terrestrial survey network employing Wild T-2 theodolite for angular measurements

Intersected peak positions determined from the solar position of Novie

Elevations determined by altimeter traverse based on Byrd Station elevation of 1530 meters. (Elevations are weak and, as a group, could be in error as much as 100 meters).

Wild T-2 used for angular measurements.

USCGS POLAR SEA - PINE ISLAND EXPEDITION

26 February-06 March, 1992

Engineers: Jon C. Campbell, Frank J. Kenny, and Gordon H. Shupe

Horizontal Datum - Position based on the Astronomic Position of Camp II determined during the 1968-69 Season.

GPS - WGS-84 pseudorange point position/ Estimated accuracy: +/- 100 meters

Vertical Datum - Mean sea level

* A - Astronomical

B- Beaconed - Signal/Cairn & monumented

U - Unbeaconed - Occupied, monumented

O - Occupied, unmonumented

I - Intersected

# Unchecked elevation

** These stations are unidentifiable

+ Quality rating (1:best: 3:worst)

The relative strength of position value shown on the Control Points Coordinates list for each quadrangle is not an indicator of the accuracy. It is a number assigned by the USGS based on the number of checks obtained for that survey point.

As an example, an occupied point with several connections to the surrounding network is a 1 (highest reliability). Whereas, a point positioned by two rays intersecting has no check and is assigned a value of 3 (lowest reliability).

(1). Indicates a checked occupied station.

(2). Intersected with 3 or more directions.

(3). Intersected station with no checks - uncertain position - use with caution.

The Thurston Island/Jones Mtn. and Hudson Mountains survey networks were established to provide control for mapping using aerial photographs. All of the individual networks are tied to an astronomic observation taken during the field season of that survey.

The Pine Island Bay Expedition GPS surveys were established to provide control for mapping using aerial photography. The coordinates provided are pseudorange point position with an accuracy of +/- 100 meters.
