OpenStreetMap - Adelaide status

I've made a reasonable amount of progress in mapping buildings around Adelaide. I started out in Rosewater, and have pushed along to Croydon.


Croydon
Unfortunately with redevelopment works in the Bowden area, its hard to trust the old satellite images - its unlikely much more will be done there.

West Croydon

Woodvillie Park

St Clair Housing Development
Interestingly has attracted a few mappers to complete roads in the area.





Woodville North
Unfortunately, bing imagery is out of date as many of the Housing Trust homes are getting knocked down.
Needs ground survey or new images to be completed.

Wingfield
Many industrial buildings mapped, but not to complete detail
 
Railyards

Port Adelaide, building map status is effectively complete.
Needs street numbering or businesses to be tagged next.

West Lakes, a small patch of mapping.
There are a few other mappers in the area, so hopefully this attracts their interest a bit.

Outer Harbour, a small patch of mapping

Glenside Area, a small patch of housing

McLaren Vale
YetiHunter is an XPlane user, and together we mapped a lot of vineyards in the area, for more realistic terrain.

Vineyards in the Hills
YetiHuntery did the majority of this area, but the satellite imagery may be out of date since the Cherryville fire.

So, why am I still at this?
I'm quite encouraged by OpenTripPlanner, as well as the already mentioned ability to use scenery in XPlane.

Going a bit further, I've had a bit of an interest in Wine and Vineyard metadata for some time. Previously, the best open data set I knew of was Freebase - here's a list of their vineyards. We tend to know which vintages of wine from what producer are good when we acquire a few favourites, but the rest is still a lot of marketing.
Why can't we trace the origins of a local wine right to the specific vineyard it came from?
Hypothetically, take your favourite bottle, and pull out your android phone. Scan the barcode, get shown on a map where it likely came from.
To find similar soil conditions, move slightly down the road - using your smart phone to help you discover less well known producers.

I've also done a little bit of work on working out what's on fire. To date, I haven't had this running as a service anywhere, but I suspect it'll be a job for my Pi.
I'm quite interested in the idea of knowing when a house or industrial area may have caught on fire - this seems like a quite valuable data set to insurance and others in the property industry.

Finally, it's kind of nice to be able to work out which houses have swimming pools or tennis courts - the key difference between an open data set like this and something based on sales or transactions is the completeness of the data - you can say with more certainty you know which houses in the area have these features.
