The present invention relates to a numerical map production system to update variations in topographic information. More specifically, the present invention relates to a numerical map production system to update variations in topographic information, which is capable of precisely sensing errors in coordinate data on the numerical map by stably functioning as a datum point. Especially, by comparing an actual positional coordinates in a photographing region and a global positioning system (GPS) positional information on the photographing region through periodic air-photographing and then by applying the information on variations in topographic to the numerical map right away, it is possible to increase accuracy in the numerical map. In addition, it is also possible to prevent lifespan shortening of modules composing a system due to deterioration by heat.
본 발명은 지형정보의 변화를 업데이트하기 위한 수치지도 제작시스템에 관한 것으로, 보다 상세하게는 기준점의 역할을 안정적으로 수행하여 수치지도의 좌표데이터의 오류를 정확하게 감지할 수 있으며, 특히 주기적인 항공촬영을 통해 촬영지역에서의 GPS위치정보와 해당 촬영지역의 실제위치좌표를 비교하여 지형변화 정보를 수치지도에 즉시 반영하여 수치지도의 정확성을 높이도록 하면서 시스템을 구성하는 모듈들이 열에 의한 열화로 수명이 단축되는 것을 방지한 지형정보의 변화를 업데이트하기 위한 수치지도 제작시스템에 관한 것이다.
