Data grid is the fundamental work of graphics drafting, scientific computation and the realization of spatial analysis. Using dynamic grid and assigning technology of spatial data, the authors have implemented interoperability of multiple-sources data. The assigned grid has multi-attributes and applies the geographic information system (GIS) and the external program to implement overlay analysis and other complicated spatial analysis functions. The merits of the dynamic grid system lie in a complete vector format and the implementation of multiple-source data merging and massive data spatial analysis. This paper has realized the land suitability evaluation through the assigning technology and the dynamic grid system.
