I'm looking for a simple explanation on how to detect if GPS coordinates fall within a polygon of points.
I would prefer an explanations that can be done using paper and pencil and not programming language specific.
If I have a list of points (latitude and longitude in degrees) that makes up a polygon. How can I tell if a point falls withing that polygon.
The only data I have access to is the polygon points and the point to check. An example is:
41.21,-104.77(point to check) then I have polygon points (
39.39 -101.69 + 48.8335,-106.2435 + 38.803,-109.5781 + 39.4413,-111.043 + 45.6336,-113.7162 + 48.8335,-106.2435)
