Any one know of an easy way to find out if a given Point is within a Polygon.

ie.

A map has an area on it defended by a Polygon.

I have a coordinate defended as a Point on the map.

I want to know if the Point is inside the Polygon?

Any one know of any simple script (java) to work this out?

Hi,

Java or JavaScript?

For JavaScript, you could simply use Mapbox's Point in Polygon plugin for Leaflet (https://github.com/mapbox/leaflet-pip).
If you need more complex operations, try Turf (https://github.com/turfjs/turf).

Hope this helps.
