关于Shapefile的multipoint feature和point feature,ESRI是如下定义的:multipoint feature A feature that consists of more than one point but only references one set of attributes in the database. For example, a system of oil wells might be considered a multipoint feature, since there is a single set of attributes for multiple well holes.point feature A zero-dimensional abstraction of an object; a single x,y coordinate pair that represents a geographic feature too small to be displayed as a line or area at that scale. 在MapInfo高版本中(大概是6.0之后)数字化的点图层转换为Shapefile格式会变成multipoint feature,在实际应用中multipoit feature会给 使用者带来不方便,需将 multipoint feature 转换为point feature格式。这里介绍笔者在实际工作中使用的转换方法:
第一种方法,使用低版本MapInfo的通用转换器转换,把MapInfo的tab格式转换为shp格式时生成的是point feature。
第二种方法,使用ArcGIS的ArcToolbox里的Feature to Point工具转换。虽然ArcGIS帮助里没有介绍Feature to Point可以把Shapefile格式的 multipoint feature 转化为point feature功能,但这个工具的确可以转换,比较好用。
希望以上两种方法能解决您的问题,祝君好运![]()
