Check if geo-point is inside or outside of polygon

Question

I am using python and I have defined the latitudes and longitudes (in degrees) of a polygon on the map. My goal is to check if a generic point P of coordinates

Answer 1

There is also an emerging python library turfpy. which is used for geospatial analysis.

PyPI

Example:

from turfpy.measurement import boolean_point_in_polygon
from geojson import Point, Polygon, Feature

point = Feature(geometry=Point((-46.6318, -23.5523)))
polygon = Polygon(
    [
        [
            (-46.653, -23.543),
            (-46.634, -23.5346),
            (-46.613, -23.543),
            (-46.614, -23.559),
            (-46.631, -23.567),
            (-46.653, -23.560),
            (-46.653, -23.543),
        ]
    ]
)
boolean_point_in_polygon(point, polygon)
