shapely LineString组成polygon polyshape函数 polyshape 函数可创建由二维顶点定义的多边形,并返回具有描述其顶点、实心区域和孔的各种属性的polyshape对象。例如,pgon = polyshape([0 0 1 1],[1 0 0 1])将创建由四个点 (0,1)、(0,0)、(1,0) 和 (1,1) 定义的实心正方形。 pgon = polyshape(x,...
我试图检查我在代码中输入的对象是否是带有assert函数的ShapelyPoint、assert或Polygon几何图形。' or type(geom) == 'shapely.geometry.linestring.LineString' or type(geom) == 'shapely.geometry.polygon.Polygon', "Input should be aShapelygeometry!" ...
we can have a “collection of Points” or a “collection of Polygons”. These are used when we want to group together several points/polygons/objects in a single object. These are also often given to us as a return value in certain operations, like the intersection...
elements in collections are ordered by geometry type: by descending dimension and multi-types first (MultiPolygon, Polygon, MultiLineString, LineString, MultiPoint, Point). Multiple elements from the same type are ordered from right to left and from top to bottom.It...
from shapely.geometry import Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon Shapely通过它的x、y坐标来定义一个点,像这样: Point(0,0) 我们可以计算有形状的物体之间的距离,如两个点: a = Point(0, 0) b = Point(1, 0) ...
The single-part geometries (Point, LineString, Polygon) already didn't support those features, and for those classes there is no change in behaviour for this aspect.Interoperability with NumPy and the array interfaceConversion of the coordinates to (NumPy) arrays...

Returns a representation of the point or smallest rectangular polygon (with sides parallel to the coordinate axes) that contains the object. object.parallel_offset (distance,side,resolution=16, join_style=1,mitre_limit=1.0) Returns a LineString or MultiLineString geometry at a distance from the ...
