aeropolygon method of strip aerotriangulation
Earth science; Mapping science
The relative orientation of successive models of a strip, on a stereoscopic plotting instrument, without using any auxiliary data.
azimuth transfer
Earth science; Mapping science
The process of connecting, with a straight line, the nadir points of two vertical photographs selected from overlapping strips.
adjoiner
Earth science; Mapping science
The land in contact with the property of immediate interest.
right angle
Earth science; Mapping science
A plane angle such that exactly four rotations in the plane, initial side to former position of terminal side, about the vertex bring the angle back to its original position. ...
closed bay
Earth science; Mapping science
(1) A coastal indentation which encloses an area greater than that inclosed by a semi-circle whose diameter is a line drawn between the extremities of the indentation. (2) A ...
base line reduction to sea level
Earth science; Mapping science
Conversion of the measured length of a base line to the length of the vertical projection of the base line onto a specified surface defined by reference to mean sea level. ...
principal point assumption
Earth science; Mapping science
