The bathymetric chart of the Nuka Bay area, Alaska, is based on U.S.C.&G.S. Chart 8530, and over 750 km of additional sounding lines made in 1965 and in 1968. Continuous reflection seismic records made along the same tracks as the bathymetric profiles served as the basis for the Isopach map....
Weighted triangulation adjustment
Walter L. Anderson
1969, Open-File Report 69-10
The variation of coordinates method is employed to perform a weighted least squares adjustment of horizontal survey networks. Geodetic coordinates are required for each fixed and adjustable station. A preliminary inverse geodetic position computation is made for each observed line. Weights associated with each observed equation for direction, azimuth, and...
