摘要
The present invention relates to a geodetic surveying system for survey method of a datum point and, more specifically, relates to a geodetic surveying system for survey method of a datum point, wherein a ground subsidence state of a national reference point and a degree of settlement thereof are easily checked with the naked eye to calculate national reference point height information before the ground settlement as an approximate numerical value. A business for project implementation with little time can quickly perform geodetic surveying work by using the calculated national reference point height information with the approximate numerical value. Moreover, a packing member is checked and can be smoothly separated and replaced.
