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.

Horizontal Datum - Positions based on the Astronomic Position of Wetmore
Astro determined during the 1969-70 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 reliability 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.
USGS/BAS LANDSAT GEOCEIVER PROJECT
1975-76 Season
Engineers: Karl W. Gatson and James W. Schoonmaker, 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 are geodetic heights corrected to the geoid
using the Goddard Earth Model (GEM) 10B.

GEM 10B.

# 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
5. Limited number of satellite passes - no position reliability established
++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
6. Limited number of satellite passes - no position reliability established
