METHOD FOR UPDATING GIS NUMERICAL MAP OF SURVEYING INFORMATION OF STRUCTURAL FACILITIES ALONG ROAD BY USING VEHICLE WITH GPS RECEIVER AND LASER MEASURING INSTRUMENT

摘要

The present invention relates to a method for updating a GIS numerical map of roadside facility surveying information using a GPS receiver and a vehicle equipped with a laser measuring instrument. More specifically, the present invention relates to a position coordinate of roadside facilities while driving a vehicle equipped with a GPS receiver and a laser measuring instrument. It relates to a method of measuring the size, etc., and immediately correcting the information to update the GIS numerical map in real time. This can be applied very easily when acquiring local digital terrain data such as facilities around roads, high accuracy can be obtained by using the laser's straightness, and digital maps such as urban areas where the surrounding environment changes day by day. You can update quickly and accurately for.;Geographic Information System (GIS), Global Positioning System (GPS), Digital Maps, Positioning, Roads, Nearby Facilities, Surveying Vehicles, Laser Instruments
