what if want remove overlay item under condition if location on gps equal overlay item longitude & latitude , how condition should written ?!
other question : due un accuracy of gps need add delta " delta make square around overlay item because if position near area of on lay item suppose delta cant never int or float should ?
you'd need loop through overlays when updated position , see if of them @ same spot , remove it. @ current position , position of overlay.
