Australia » Victoria » Melbourne
I signed up for OpenStreetMap about a year ago, and there were plenty of warnings that it's very addictive, but little did I know!!!
I do mapping in spits & spurts (like a lot of other people I'd imagine).
Turns out I have done a fair bit since I signed up:
Looks like I'm the biggest contributor in greater Melbourne, scary stuff.
I've traced streets, added a lot of names and added some POI's like parks, foot/bike paths, pubs, schools etc.
Rough order of Suburbs I've done:
Since I don't have a GPS, I trace from Yahoo! imagery and fill in as many details as possible.
I've noticed that there is a fair amount of pride/possessiveness around the contribution that OSM users have made, and I'm no different.
I get annoyed when other users come through and add inappropriate tags (not what was on the ground, "for the renderer", not "best-practise" etc.), move carefully smoothed ways around/offset. I guess the "pride" of one's contribution is a double edged sword.
Good tools for letting me know when someone has editing "my areas" would be fantastic, and I've just signed up for Itoworld's osmmapper (RSS feeds of changes to specific areas). But I think it's hard to communicate what has changed, how do you convey changes in a concise/meaningful way?

You've done a great job Blue.
I did notice when you first started. I went down and traced some roads with my GPS at the end of Arden St, and when I got home and went to add them to the map, I saw that you had already done them.
Also would love to know how you generated the graphic, very interesting!
It was that that inspired me to learn how to use josm with the yahoo imagery.

That's some fine work, BlueMM
Pete, that grphic comes from itoworld (www.itoworld.com)
That's how I keep track of the changing bits as well. Very cool.

Nicely done there blue,
I've been a bit shy using potlatch, mainly because I haven't used it that much.
I prefer cycling with my GPS unit, and a digital camera, then using JOSM to do the rest.
I do like entering lots of detail in, recently drinking fountains, toilets, post boxes and speed humps.
And yeah, OSM is quite addictive :D
Hopefully sometime soon all the melb suburbs will be completed, and all the nice details ... then I guess we'll move out to the more regional areas and map them too!

Nice work. I used the streets BlueMM entered along with my garmin to work out the best way home from East Keilor tennis club last Friday. There is quite a lot of work happening already in the "regions" particularly in the Latrobe valley. However you do need a GPS when working outside of the high res Yahoo coverage areas.

Well Done, keep up the good work.
I am doing the same in the Coffs Harbour region but don't have any decent Yahoo Imagery to work with.
I was under the impression that using a resource such as Yahoo was sailing a bit close to the wind as far as copywrite is concerned. I have been using my GPS as the primary tool. If it doesn't come off the GPS it doesn't go onto OSM. The only time I have gone outside that was to trace a couple of inlets from Oziexplorer to show shorelines.
I was warned it is addictive and now I am suffering from the addiction. I do fire permits for the Rural Fire Service and use this to get some of the really out of the way places logged such as private access roads.

Yahoo & OSM made an agreement that OSM could use Yahoo images to create copyright-free traces, the normal derivative clause in copyright work is waived. So using Yahoo! sat images is ok (OSM is only allowed to use it through Yahoo's API), but using something like Google is not (because, by default, everything is copyright unless granted a derivative license, and in the OSM case, needs to match their CC-by-SA or public domain license). Lots of headaches for the folks on the talk-legal mailing list.
BTW, not sure what Oziexplorer is (though I've heard of it), but I imagine it's copyrighted, therefore tainting OSM's database. I would replace the shoreline by tracing using the Landsat aerial photos & use source=landsat instead of source=yahoo (the Yahoo! background in Potlatch shows public domain Landsat at low zoom levels, which won't make it highly detailed, but it will need to be GPS surveyed eventually anyway).
The fire permit travel is gonna help a lot, I've always thought that stuff will be the last "unknown" in OSM. Imagine the day when everything in the Alpine National Park is OSM mapped!!!

Have a look at Oziexplorer here. http://www.oziexplorer.com/ It is a software package and I use Shonky's free maps which are available thru the http://www.gpsaustralia.net/forums/ . Using this setup on my laptop I can connect my Explorist 500 and have a moving map display in my vehicle and can record my tracks onto the laptop. Shonkys free maps are based on the free GA maps
Doing it this way doesn't taint the OSM project.

With changesets in the upcoming 0.6 API, there will be changesets, where users can put a comment in of what they have done.

I did some research, and I'm pretty certain it's tainted. GA maps are free as in beer but not free as in speech, they do have copyright restrictions. This has been discussed before:
Geoscience Australia Administrative Boundary data
Geoscience Australia 1:250K data
Deleting some GNB names..
[OSM-talk] OSDM data source
A few people respond "yeah, I think it's ok", but in that last listed thread, Andy Allan suggests the specific copyright license GA has for the data should be discussed on the legal-talk mailing list (it doesn't seem to have been brought up there). Then Ian Sergeant suggests the "requirement for tracking derivatives and changes to the terms and conditions of the agreement" is incompatible with OSM & it's CC-SA. Ironically, even other CC-SA data maybe incompatible with OSM (depends on what the attribution requirements are).
Shonky's copyright notice looks bad for OSM http://shonkylogic.net/shonkymaps/copyright.txt
Remember, all data is copyrighted by default (and therefore unusable for OSM), unless it's "proven" to be ok.
Hopefully all data added to OSM has source/source:name=Geoscience Australia or GA or Shonky so people can fix.
I'd recommend deleting the added data, or bringing it up on the legal-talk mailing list, so people who deal with this stuff can provide an answer.

Thanks for the info. I have aerial photos of the area that I took whilst on a helicopter joy flight. I will scale them to get the correct perspective and do a trace off them to get the inlets. This way I can remove the original trace and remove any suspicion of tainted work. It certainly a minefield for the un-initiated.
But is an addictive pastime in a healthy way, gets you out of doors and the mind and legs into gear.
