Just the other day someone had forgotten one of her many shopping bags on The Tube. It'd be quite nice to reunite people with their items, however, given that there is no useable WiFi or mobile connection underground, how would you go about geotagging its location?? Manually estimate it above ground?

TGIFound allow search for distance, so even if you report it when you have signal and out of the original spot it should be easily searchable... I am open to opinion, is there anyway to make it even more accurate during offline?
