MapInfo的空间数据处理及分析功能的研究

空间数据的处理及分析是地图制作过程中经常用到的功能.针对MapInfo平台,结合实际的工程实践经验,较详细地介绍了其空间数据合并、裁剪,不同空间数据类型提取,空间数据重叠、相交、间隙自动检查,多边形内点对象的自动选取,空间数据节点叠置、空间数据类型转换等功能,最后以空间数据的合并及裁剪为例,介绍了利用MapInfo的二次开发平台MapBasic实现数据批量处理的开发方法.

The Research of Spacial Data Processing and Analyzing Functions Based On Mapinfo

Spatial data managing project experience working on MapInfo and analyzing is an usual function when we develop map data. With the practical data software ,In detail this paper introduces the methods of the spatial data merging, clipping, date extraction of different type ,the quick check of spatial data overlaps, self- intersections and gaps, also the methods how to select point objects within polygons automatically ,overlay nodes and converse data,etc. Lastly this paper takes the merging and clipping of spatial date for example to introduce the methods how to multiple process spatial data based on Mapbasic.
