OGL_Library::Polygon Class Reference

The class provide ploygon manage. An example would be someone using their GPS-PDA to zoo guiding tour and it would to determine the user's location and provide the animal info from before mine eyes.

Detailed Description

The class provide ploygon manage. An example would be someone using their GPS-PDA to zoo guiding tour and it would to determine the user's location and provide the animal info from before mine eyes. The "Polygon class" is based on an algorithm which detections Point(GPS geodetic position) in the Polygon(GPS-Area)..
