concluded angle
Earth science; Mapping science
An interior angle between adjacent sides of a closed figure, which is obtained by subtracting the sum of all the other interior angles of the figure from the theoretical value of the sum of all the ...
geodetic anomaly
Earth science; Mapping science
The deviation of the measured value of a geodetic quantity from the theoretical value of that quantity, because there is a corresponding deviation of the Earth's actual structure at the point of ...
back bearing
