This research was conducted experiment to verify whether it can be obtain position seamlessly by using VRS-GPS (Virtual Reference System-GPS) and passive RFID (Radio Frequency Identification) at an area surrounded by canopies and buildings for realizing an advanced spatial information society based on NSDI (National Spatial Data Infrastructure). As a result, map in the GIS showed border position of between VRS-GPS and RFID can connect seamlessly. Next experiment was performed in the building by active RFID. As a result, it is difficult to obtain indoor accurate position information using only active RFID. Therefore we consider obtaining more accurate position information by using both of active RFID and passive sensors. Trial experiments shows the combination of active RFID and passive sensor is better than that of single use.
