Photo Tower Triangulation Report A report was issued on “day 18, choto tower to the Zero points. 1951, including the relation of the The values are listed as computed from the sontrol network and also from chsck computations based on observations made at the structure sites. This report is included. Adjusted Data Adjusting of the expanded soheme has been completed, and the adjusted values are included in this report. The value of the length of each line 1s independent of the route followed in the computation. All observations, ineluding the cheok observations at the structure sites, were evaluated and used in the adjustments. While this data varies from the values given in the photo tower triangulation report, the differences are small and assure that the values given in this report are within requirements. ™ the interests of eccnomy, these computations are not included in thia report. The sketches included reoord the adjusted velues determining the inter-relation of the various stations. The computations and field notes will be a part of the permanent survey recorda at the jobsite.
