SPATIAL IMAGE DRAWING SYSTEM HAVING STEREOPLOTTING INSTRUMENT CAPABLE OF PRECISION SCALE ILLUSTRATION

摘要

The present invention relates to a spatial image drawing system equipped with a stereoplotting instrument capable of precision scale illustration. More specifically, the present invention relates to a spatial image drawing system equipped with a stereoplotting instrument capable of precision scale illustration, which: fundamentally prevents an aerial photographic positive film from being superimposed by making a white board maximally in close contact with the aerial photographic positive film through a pair of pressing device units connecting an instrument main body and a cover; highly improves convenience of work by maintaining an open state when the cover is opened; and has a simplified and efficient cooling structure.;COPYRIGHT KIPO 2020
