Intersections between different objects using shapely and pyproj. Could be wrapped in geopandas

intersects_test.py

# Intersections between different objects
# This demo shows intersects function between
# Polygons (Box and Circle)
# Note that applying buffer in (m) after projection happened
#
# 1) Reproject WGS84 to Web Mercator which uses m in UnicodeTranslateError
# 2) Call intersects
from shapely.geometry import Point,Polygon
import pyproj

def proj_to_plane(lat, lon):
	srcp = pyproj.Proj(init='epsg:4326')  # WGS84: Lat Lng
	destp = pyproj.Proj(init='epsg:3857') # Web Mercator which uses m
	return pyproj.transform(srcp, destp, lon, lat)	

poly = Polygon([
		proj_to_plane(40,-90),
		proj_to_plane(40,-79),
		proj_to_plane(49,-79),
		proj_to_plane(49,-90),
		proj_to_plane(40,-90)	
	])

(rprojx,rprojy) = proj_to_plane(44,-88)
pt = Point(rprojx,rprojy)
circle = pt.buffer(300*1000) # 300km circle

result = poly.intersects(circle)
print(result)

Another intersection example between a box and circle(s) look like this: https://twitter.com/objectgraph/status/740006995399446528
