METHOD FOR CONSTITUTING GIS OF RIVER INFORMATION BY UPDATING RIVER AREA FACILITIES INFORMATION TO DIGITAL MAP VIA MOBILE INTERNET

摘要

The present invention relates to a method for constructing a river information GIS for updating river basin facility information to a digital map database through a wireless Internet. More specifically, the recent information on river basin facilities and changes that are not reflected in the river digital map can be captured by digital photogrammetry using two vehicles equipped with a CCD camera, GPS, and INS. The present invention relates to a method of updating a digital map database by correcting by corrected coordinates of a reference point having accurate coordinates and transmitting the data to a GIS server through a wireless terminal.;According to the present invention, not only can the river basin facility information be quickly updated in the GIS system, but also by updating in real time through the wireless Internet, the measured data are corrected at the measurement site, so that it is faster and more accurate than the conventional method of calibrating indoors. Simplicity has the effect of providing users with a digital map corrected in real time.
