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, and values in parenthesis
on the flight lines indicate starting amd ending frame #'s.
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.

Control Network. (Detail Quadrangle Control Network not shown because
there is only 1 control point on quadrangle. (Click on quadrangle control

BYRD STATION TRAVERSE
1959-60 Season
Engineer: William H. Chapman
Intersected peak positions determined from the solar position
of M258 (Adjusted to Marie Byrd Land Electronic Traverse of 1966-67-68).
Elevations determined by altimeter traverse based on Byrd
Station elevation of 1530 meters (The altimetry elevations have been adjusted
to agree with the elevations determined from the Marie Byrd Land Electronic
Traverse of 1966-67-68).
Wild T-2 used for angular measurements.

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.
