Abstract: | The research of temporal GIS is one of the hotspots in GIS, however the data are stored in different databases and the inquiry and analysis will be very complex and fussy. Together with the technology of spatial database the paper puts forward to a double deck inquiry model, which can make it easy to fulfill spatial - time inquiry. |
