SYSTEM FOR MEASURING USING EQUAL DISTANCE SURVEY IN GEODETIC SURVEYING

摘要

PURPOSE: A geodetic survey system for checking geographic intelligence by a reference point by checking the GPS and the geographical features through observation is provided to continuously utilize a leveling rod body even after replacing the gradation unit when the gradation unit is damaged as the gradation unit of the leveling rod is attachable and detachable. CONSTITUTION: A geodetic survey system for checking geographic intelligence by a reference point by checking the GPS and the geographical features through observation comprises a leveling rod body(110), a gradation unit(120), a leveling device, a data processor, and a storage unit. The gradation unit is inserted into the gradation displaying units(111,112) detachably of the leveling rod body and the gradations(121) marked on one surface of the gradation unit is visually exposed through a transparent surface of the gradation displaying units. The gradation unit is made of a transparent or semi-transparent material penetrating through the lights of an LED(114). The gradations are marked by using fluorescent materials, thereby becoming sharp by the lights of the LED. The leveling device measures data with respect to a distance to the leveling rod body by using an embedded laser distance measuring unit. The data processing device receives the distance data and performs a correct distance test. The storage unit receives attribute data and stores the same in an allocated domain.
