I’m a courier who uses the information on this map courtesy of OSMAnd on Android. My main reason for using these maps is that I can download them and use them offline. All I need is a gps connection for them to work.

I have observed that there is a lot of information missing on the map and updates needed so have taken to adding building numbers and gpx traces to my profile.

I also raise notes so that others can use gpx traces etc to resolve them.

If everyone did a little of this wherever they went our maps would update so much quicker.
