There isn't a one-to-one relationship between addresses and lots. Strip malls both here and in the US will sometimes have an entirely different address (not just suite number) for each store even though they may be on one lot. Similarly you can get multiple buildings on one lot with different addresses. I have seen this both here and with some US data. These exceptions are less common for residential areas but you still see some. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
