"贴紧"多边形一起 [英] "snapping" polygons together
问题描述
首选QGIS / ArcGIS或Python库解决方案(欢迎使用算法建议)
老派的ArcInfo有一个干净的功能 - 我认为他们在地理处理方面做了同样的事情,如果你使用geodb。在该功能中,您设置了将线条和点集合在一起的容差。干净摆脱所有这些细条(你所谈论的技术术语)。

I have a set of polygons representing administrative districts. The districts were digitized by hand, and there are small spaces between polygons where the polygons should be touching. There are probably also overlapping polygons. How can I have the polygons snap together, filling the gaps and removing overlap?
QGIS / ArcGIS or Python library solution preferred (but algorithm suggestions welcome)
Old school ArcInfo had a "clean" function - I think they did the same thing in geoprocessing if you use a geodb. In that function you set a tolerance for snapping lines and points together. The clean gets rid of all those slivers (the technical term for what you are talking about).
