摘要
利用一种动态网格,通过空间数据赋值技术,将多源数据赋值给网格,以完成空间数据的互操作。赋值后的网格系统具有多种属性,通过地理信息系统和外部程序设计能够实现叠置分析等复杂的空间分析功能。采用动态网格系统完全的矢量格式和实现多源数据融合的优点,以实现海量多源数据的空间分析。通过赋值技术和动态网格系统实现了土地适宜性评价。
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 interopera- bility 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.
