spatial overlay analysis

基本解释

By spatial overlay analysis of slope gradient and vegetation index, it was found t.
这一点可以通过梯度分析来得到证明，梯率分析重点在于物种分布重叠区域。
The spatial analysis, including topological analysis, overlay analysis, buffer analysis and so on, is achieved.
实现了图形对象的拓扑分析、叠置分析和缓冲区分析等空间分析功能。
Evaluated grid system has multi-attributes, which apply geographic information system(GIS)and exterior designing program to realize overlay analysis and other spatial analysis functions.
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；
