TMA FLIGHT LINE Map and Control Point Locations
FLIGHT LINE Information - flight lines indicated by dark lines, direction
of flight indicated by arrowheads at end of each FLIGHT LINE, TMA # (photo
flight #) indicated by number on FLIGHT LINE. Values in parenthesis on a
FLIGHT LINE indicates range of photos in a FLIGHT LINE.
Control Photos - number at small arrow on FLIGHT LINE indicates frame
#, arrow indicates direction of view (R or L indicates right or left view,
frame # and V in parenthesis indicates vertical view), click on frame #
to display browse photo, thumbnail versions of control photos appear below.
Control Points - control point location indicated by red square with
station name adjacent, click on red square to go to individual control folder.

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 - The positions are based on WGS 66 datum. The adjusted
network was fitted to the geoceiver stations by a least squares transformation
and the residuals were less than two meters.
Vertical Datum - Geodetic heights corrected to the geoid using NASA
GEM 10B. No direct connections to sea level were made.
The position reliability/elevation reliability 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 5 (lowest reliability).

B- Beaconed - Signal/Cairn & monumented
U - Unbeaconed - Occupied, monumented
O - Occupied, unmonumented
I - Intersected
# Unchecked elevation
** These stations are unidentifiable
+ Position Reliability
1. Established by Doppler Satellite measurements, or a checked occupied
station
2. Position established by side shot from main line
3. Intersected with three or more directions
4. Intersected station, no checks - poor position
++Elevation Reliability
1. Elevation measured by Doppler Satellite methods and occupied stations
with checked reciprocal vertical angle elevations
2. Elevation established by side shots from main line
3. Intersected station with elevation checks from several vertical angles
4. Intersected station with elevation checks from two or more vertical
angles
5. Intersected station with no check elevation - very poor elevation
