public boolean coordinateInZone ( Id < ActivityFacility > zoneID , Coord coordinate ) { Point point = MGC . xy2Point ( coordinate . getX ( ) , coordinate . getY ( ) ) ; return pointInZone ( zoneID , point ) ; }
determines if a given coordinate lies within a selected zone . the shape of the zone is defined by the respective zone geometry in the shape file
