  • SYSTEM AND METHOD FOR DETERMINING POSITION WITHIN OR WITHOUT A COMPLEX POLYGON GEOFENCE
    Publication number: 20090093958
    Abstract: A geofence system which locates a position as within or without the complex polygon type geofence using a simplified algorithm. The algorithm obtains a position and compares it to the polygon by establishing a ray from the position constructed in a cardinal direction of the coordinate system. The “polarity” of the count of intersections between the ray and geofence indicates whether the position is inside the geofence or not.
