ORVILLE COAST
1978-79 Season
Engineers: David Reed, Eberhand G. Schirmacher, Robin Schumtzler,
and Harry Zohn, Jr.
Intersected peak positions determined by terrestrial surveys
employing Wild T-2 theodolite for angular measurements and Electro-tapes
for distance measurements from positions developed by geoceiver (Doppler)
observations.
Elevations based on sea level using the Goddard Earth Model
(GEM) 10B.
ELLSWORTH LAND TRAVERSE-1962
(ORIGINALLY NAMED ANTARCTIC PENINSULA TRAVERSE)
1961-62 Season
Engineer: Conrad G. Merrick
Intersected peak positions determined from primary traverse
stations
Elevations determined by altimeter traverse based on Camp
Minnesota elevation of 1250 meters
Reliable coordinates not available because of equipment
malfunctions during the traverse.
Stations are shown for inventory purposes only

Horizontal Datum - Position based on WGS 66 datum by a 19 satellite
pass, position measurement at station 22251 (Base Camp). Accuracy estimated
to be +/- 15 meters.
Vertical Datum - Geoceiver height corrected to sea level using NASA
GEM 10 geoid model.
* 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 Orville Coast and the USGS/BAS Landsat Projects survey networks
were established to provide control for mapping using aerial photographs
and satellite imagery. All of the individual networks are tied to an astronomic
observation taken during the field season of that survey or doppler satellite
position.
