Analytical stereoplotterとは 意味・読み方・使い方

With the introduction of computers, the analytical stereoplotter became a popular machine of choice photogrammetry in the late 1960’s to 1970’s. A stereoplotter is an instrument that uses stereo photographs to determine elevations for the purpose of creating contours on topographic maps. Computers brought the capability to execute more precise calculations that ensure additional accurate output instead of approximations. This innovation also allowed a shift to a digital format rather than paper. Analytical stereoplotters edged out their analog predecessors and became the primary method of acquiring elevation data from stereo photographs.
