Abstract: Dynamic data loading based on data page can preferably solve the visualization of huge data of DEM and DOM in CyberCity GIS.But if the same tactic is used to handle the indoor scene of buildings which maybe lengthways very huge,it may cause problems.A method for data dispatch and management of indoor scene based on Cell-Portal from games for reference is used.Experiment demonstrates that it needs not increase the workload of data production and can fit the demand of the further development of CiberCity GIS.
