SYSTEM FOR UPDATING NUMERICAL MAP OF CHANGED LANDFORM AND LANDMARK BY GPS CHECK

摘要

The present invention relates to a system for updating a numerical map of a changed landform and landmark by a GPS check. The system comprises a reference station, a photographing apparatus, and a numerical map production center. When a name of a building or facilities or information of representative companies in the building is changed, people who are a building (facilities) owner or a representative for companies in the building and relevant to the changed information can transmit a fact of geographical information change in the numerical map and specific changed information to a GIS server through a kiosk-type terminal device. The GIS server applies information, received frequently from the kiosk-type terminal, to a relevant numerical map. Therefore, the GIS server can continuously maintain correctness of the numerical map by newly generating a final update version of the map every time geographical information in the numerical map changes. More accurate photographing can be performed and the numerical map can be updated and manufactured by maintaining the photographing apparatus in a horizontal position all the time.;COPYRIGHT KIPO 2016
