基于空间分析方法的目标区快速选择及应用研究

Fast Selection and Application of Target Areas Based on Spatial Analysis

针对多目标区的批量、准确获取,目前大部分GIS或制图软件仍然无法直接实现。从空间分析角度着手,对多目标区快速选择问题进行了探讨,引入了多边形选择的概念,给出了运用MapGIS的空间分析、label点合并等功能实现这一目标的一般性步骤,并且结合土地整理项目区划定和全国第二次土地调查建库基本农田上图这两个实例,介绍了该方法的具体应用。在此基础上,给出了该方法实现的一般算法,并对其应用前景进行了展望。

Nowadays, mass and accurate acquisition of multi-target area can not be realized directly by most GIS or mapping software. This paper explores the issue from the perspective of spatial analysis, introduces the concept of polygon selection, and gives general steps to achieve this goal by MapGIS. And then boundary setting of land consolidation area and basic farmland plan mapping are presented as two examples to illustrate its application. On this basis, the paper gives a general algorithm for implementation of the method and discusses the prospective of the application.
