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

Another way to do it is by using the even-odd algorithm explained in this link https://wrf.ecse.rpi.edu//Research/Short_Notes/pnpoly.html The python code is given in wikipedia https://en.wikipedia.org/wiki/Even–odd_rule

Folks, just remember that the ORDER OF POINTS that make the polygon MATTER! I mean, different order results in different polygons.
