摘要
The present invention relates to a wireless terminal system for constructing a river information GIS by 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. It relates to a wireless terminal system for correcting by the calibration coordinates of the reference point having a transmission to the GIS server through the wireless terminal to update the digital map database.;According to the present invention, it is possible not only to quickly update the changes in the river flows to the GIS system, but also to update in real time through the wireless Internet, so that the measured data are corrected at the measurement site, so that it is faster than the existing system of calibrating indoors. There is an effect that can provide users with a wireless terminal system that can correct the digital map in real time.
