WebbYou could try shapely. They describe spatial relationships and it work on windows. The spatial data model is accompanied by a group of natural language relationships between geometric objects – contains, intersects, overlaps, touches, etc. – and a theoretical framework for understanding them using the 3x3 matrix of the mutual intersections of … Webbfrom shapely import wkb for lake in query: point = wkb.loads(bytes(lake.point.data)) print point.x, point.y [sqlalchemy]相关文章推荐 sqlalchemy:多个关系(通过关联对象多对多) sqlalchemy
