Trianculation Survey
~
lowe
J me
common to both the Simmer and the Bowditch Surveys,
12,
1953
As the observation
point cannot be fecovered it is plamned to use these stations as the origin of geographic pesition and azimith for our survey, They should be
tied to the closest station of the new survey by precise angle and
Gistance and it 1s desirable thet thie work be completed as soon 4s
possible. This information is required to complete the computation end
adjustment of the primary net and is of higher priority than Location of
the third order stations,
At the time the local triangulation survey in the Dog-George area is made,
U. &. Navy Stations Mon end Gell should be tied in to this survey.
This
will provide an additional check between the surveys and will be of value
in determining the equation between the preliminary coordinates and the
final adjusted grid.
