| Abstract: | We present an integrated mobile 3D GIS system in a client-server architecture,which streamlines the processes across real-time field data collection,dynamical computer modeling,and human-machine interoperation.In this system,smart-phones run as GIS clients to collect local field information and communicate with remote GIS servers by wireless network.The GIS server stores the data from smart-phones into geospatial databases,builds 3D scenes dynamically,and feedbacks them to all its connected GIS clients.A prototype of the mobile 3D GIS system has been developed using C/C+ + and VB.Net and tested in Beijing.The results show that this mobile solution could significantly improve the efficiency of field data collection. |
