PURPOSE: A geospatial information survey system using a mobile communications terminal is provided to improve the precision of a location information service compared to a location information service provided by a general mobile communications terminal. CONSTITUTION: A geospatial information survey system includes a DGPS(Differential Global Positioning System) receiver(10) and a data collector(120). The planar error of the DGPS receiver is guaranteed to have the precision within 1.0M. The data collector is equipped with a data receiving part(121), a display part(123), an input part(127), and a data processing part(125). The data receiving part collects data and materials transmitted from a mobile device. The display part displays the data collected at the data receiving part on a screen for the confirmation of a user. The input part is equipped with multiple function keys, thereby enabling the user to manipulate input signals. The data processing part controls the operations of the input part, data receiving part, and display part. |
