用于空间分析的栅格中间层构建流程与方法研究

The Building Process and Method of Spatial Analysis Driven by Raster Intermediate Layer

从构建能直接用于空间分析及辅助决策的栅格中间层数据入手,将其划分为地形基础因子、地形特征、专题应用栅格中间层,用层层递进的栅格中间层数据驱动空间分析全流程,并依据影响因素确定性与否,提出二值化与模糊综合评判分析方法,进而形成栅格中间层支持的空间分析解决方案,以期为地理空间辅助决策提供更加完备的数据支持,减少空间分析处理的技术难度,实现从数据到知识的转化,提高空间分析辅助决策的质量和效率。

This paper tries to create the raster intermediate layers used directly to spatial analysis and assistant de- cision-making. It then divides the raster intermediate layers into terrain foundation factors, terrain features and top- ics application. It final puts forward the solution of spatial analysis based on the raster intermediate layers. The so- lution drives all the full flow using the gradual refinement raster intermediate layer data. And this paper puts for- ward the method based on binaryzation and fuzzy comprehensive evaluation according to the influence factor. This solution not only offers the more perfect data but also reduces the technical difficulties for spatial analysis. At the same time the solution realizes the transform form data to knowledge, raises the quality and efficiency of spatial a- nalysis.
