Matiowaces ote «Reproduced from the holdingsa Pacific Southwest RESIDENT ENGINEER Bag David L. Nerver, dr. 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. David L, Narver, dr.
