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

MARIE BYRD LAND CONTROL

Edward VII to Getz Ice Shelf Area

1966-66 Season

Engineers: Thomas Bray, DeWayne Faulkender, Charles Morrison, Joe Strange

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

DKM-3A was used for astro measurements.

Horizontal Datum - Positions are based on the Astronomic Position of Snoopy Astro determined during the 1967-68 Season.

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 Marie Byrd Land survey networks are individual networks with positions based on astronomic observations taken during the field season of that survey and were established to provide control for mapping using aerial photographs.
