[Talk-us] Am I doing this right? Houses w/ addresses

In areas with detached houses, the Android app Keypadmapper has worked
pretty well for me. Once house numbers get too dense (worst case: Montreal,
where each apartment in a duplex or triplex will have it's own house
number) it starts getting tricky assigning the number to the correct
building. And yeah, Mapillary imagery can definitely be useful for address
data.
