PURPOSE: A geodetic survey system renewing numeric information through a displacement confirmation and processing the geodetic survey of a geographical feature based on a GIS(Geographic Information System) is provided to stably install a coordinate collecting device in a top story of a building, thereby accurately confirming a GPS coordinate of a corresponding spot. CONSTITUTION: A geodetic survey system comprises a numerical information DB(11), a drawing image information DB(12), an image processing module(13), an input/output processing module(14), a coordinate collecting device, and a collected data processing module(15). The numerical information DB saves numerical information including a GPS coordinate of an artificial structure. The drawing image information DB saves drawing image information in which a building image of the ground and artificial structure are drawn. The image processing model combines numerical information respectively searched in the numerical information DB and drawing image information DB with corresponding drawing images, thereby image-processing as a numerical map. The input/output module outputs the numerical information transmitted from the image processing module. The coordinate collecting device is installed in one spot of the artificial structure, thereby measuring and collecting collection information including the data related the GPS coordinate of the one spot. The collected data processing module calculates the data related the GPS coordinate among collection information transmitted from the coordinate collecting device, thereby confirming an average value.
