shapely.equals_exact
shapely.equals_exact#
- equals_exact(a, b, tolerance=0.0, **kwargs)#
Returns True if A and B are structurally equal.
This method uses exact coordinate equality, which requires coordinates to be equal (within specified tolerance) and and in the same order for all components of a geometry. This is in contrast with the
equals
function which uses spatial (topological) equality.- Parameters
- a, bGeometry or array_like
- tolerancefloat or array_like
- **kwargs
For other keyword-only arguments, see the NumPy ufunc docs.

equals
Check if A and B are spatially equal.
Examples
>>> from shapely import Point, Polygon >>> point1 = Point(50, 50) >>> point2 = Point(50.1, 50.1) >>> equals_exact(point1, point2) False >>> equals_exact(point1, point2, tolerance=0.2) True >>> equals_exact(point1, None, tolerance=0.2) False
Difference between structucal and spatial equality:
>>> polygon1 = Polygon([(0, 0), (1, 1), (0, 1), (0, 0)]) >>> polygon2 = Polygon([(0, 0), (0, 1), (1, 1), (0, 0)]) >>> equals_exact(polygon1, polygon2) False >>> equals(polygon1, polygon2) True
