Application of Real Time GIS, Remote Sensing and IC Tag for Realization of Geospatial Information Society

Our country is experiencing an aging society, for example, pedestrian space should be safe and give a relief. One of the methods to ensure this society is to obtain absolute position with high accuracy. Therefore, we suggested here to make Universal Map (UM) with a large scale by using REAL TIME GIS with mobile mapping. The purpose of the research was to confirm whether absolute positions can be obtained accurately in mobile mapping. For the purpose, an experiment was performed on our campus at Kanazawa district in Japan by using a D-GPS and a VRS-GPS. As a result, it became clear that one could not receive accurate data in any experiment fields. To solve these problems, we adopted IC tags which are new ubiquitous technology. Therefore, it is recommended that the UM be made by the REAL TIME GIS and IC tags.
