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.

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.
