A COMPUTER-READABLE STORAGE MEDIUM HOLDING THE COMPUTER PROGRAM FOR CONSTITUTING GIS OF RIVER INFORMATION BY UPDATING RIVER PATHWAY CHANGES TO DIGITAL MAP VIA MOBILE INTERNET

摘要

The present invention relates to a recording medium having recorded thereon a program for implementing a method of constructing a river information GIS for updating a fluctuation of a stream euro in a digital map database through a wireless Internet. More specifically, recent river flow changes that are not reflected in the river numerical map can be captured by digital photogrammetry using two vehicles equipped with a CCD camera, GPS, and INS. The present invention relates to a recording medium having recorded thereon a program for implementing a method of updating a digital map database by calibrating by correction coordinates of a reference point having a transmission point to a GIS server through a wireless terminal.;According to the present invention, not only can changes of river flows be quickly updated in the GIS system, but also are updated in real time through the wireless Internet, so that the measured data are corrected at the measurement site. In this way, a program that implements a method of correcting a digital map in real time can provide a user with a recorded recording medium.
