At present, RFID indoor positioning data visualization methods are simple and the visual effect is not ideal. To solve this problem, an RFID indoor localization algorithm is proposed for a geographic information system. Furthermore, the indoor positioning algorithm balances the tradeoff between realtime operation and positioning accuracy. Compared with the conventional LandMarc algorithm and its improved Vire algorithm, the complexity of the equipment is simplified and the running time is reduced in the positioning process. Experiment results indicate that the proposed system with RFIDbased indoor visual positioning scheme can work efficiently.
