| Abstract: | Based on theories about urban land-price monitoring and using the integrated data model of raster and vector, together with time slice snapshots spatiotemporal model and object-oriented spatial data organizing methods, an information system for urban land price monitoring has been designed. By using topology and spatial analyzing theories, this system fulfills the function of urban land-price monitoring and effectively achieves purposes such as land-patch querying, land-price interpolate, DTM illustration of spatial distributes of land-price and dynamic adjustment of land-grade boundaries. And by using grid trend probing methods, this system can also solve problems with the display of raster data. |
