Find intersection vertices of two polygons

Question

I have defined two polygons and I can find whether they intersect or not. I need to find the intersection vertices if they intersect or not ?

How can I do that ?

p1 = Polygon([(0,0), (1,1), (1,0)])
p2 = Polygon([(0,1), (1,0), (1,1)])
print(p1.intersects(p2))

This gives whether the polygons intersect but how to find the intersection vertex. I tried the following but it gave an error:

print(p1.intersects(p2).coords)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'bool' object has no attribute 'coords'

Answer 1

intersects() method returns True or False (Boolean) in shapely. You have to use intersection() method.

p1 = Polygon([(0,0), (1,1), (1,0)])
p2 = Polygon([(0,1), (1,0), (1,1)])
print(p1.intersection(p2))

# OUTPUT
# POLYGON ((0.5 0.5, 1 1, 1 0, 0.5 0.5))
