Over the last month or two I've started to put more time into adding addresses in residental areas in my local area and according to Pascal Neis' great site, I have over 2,000 pieces of address data added since the beginning of the year. At this rate, by the time I've finished with my small city I will probably have over 100,000 pieces of address data added.
Here's the kicker though, until recently I was not aware of the importance/relevance of address data in OSM and I've done A LOT of mapping of the last 13 months.
Initially when I started I used my Android phone and Vespucci which has been my weapon of choice while out and about however for this kind of detail I found it too awkward and tried out a few other apps. I tried Keypadmapper and OSMPad and in the end settled on OSMPad simply because I could see exactly where on the map I was placing the address marker as I can't always maintain GPS lock. The ability to cache maps was also appealing for areas where there was a poor data connection.
How I gather my address info now is in 3 stages:
- I add the buildings first(adding addr:street),
- then go survey,
- then dump the traces I've collected into JOSM and add details to all the buildings (addr:housenumber).
There are 2 additional benefits/side effects of doing it this way.
First, it is forcing me to go back over every single street, road, alley, walkway etc in my city and I am refining alignment, adding missed details (street lighting, speed bumps, stop signs etc) and generally improving every square inch of the map for my city.
Second, I am revisiting all of these areas again for a second time, however, where previously I would have just gotten the name of a housing estate from a sign at the entrance and moved on to the next one, I am now going INTO every estate and surveying all of it and finding
- other estates/apartments tucked in the back that are not signposted at the main entrance
- house names
- guest houses
- small businesses run from the home
Hopefully this post can help others to get started on this. Its not a bible on how to do it, merely a few pointers on how to get started
