OpenStreetMap
"Bunker Bash" Classic Military Vehicles and Living History Event mapping...
Дасланы RogerStenning 5 Травень 2010 на English. Апошняе абнаўленьне 6 Травень 2010.Well, silly me, I volunteered to sort out the map for the event on a GPS survey basis. So, a fortnight ago, I was out getting sunburnt, PDA in hand, GPX tracking and POI-ing the ground in Kelvedon Hatch in Essex. The result is as you now find the map, once it's updated/refreshed today...
What you're seeing is the track plan of the event as it'll be over the weekend of 15th-16th May; there are a couple of areas plotted for car parking and such like, but specific items aren't going on the map, as they're subject to change on the day (where the various trade stands, exhibitors, and so on, are going to be placed, for example).
The surveying took the best part of five hours. Plotting it on the map took a week and a half!
Oh yeah... WHERE is this taking place? See their website - it's a heck of an event!

You should have posted a URL of the location, or at least given the co-ords for it...

John, I did - the article should have picked up on the OSM area, and I certainly posted the event URL at the foot of the diary entry. Anyhow, the coords on the OSM are:
osm.org/?lat=51.67021&lon=0.26254&zoom=15&layers=B000FTF
And the event is being held at Kelvedon Hatch Secret Nuclear Bunker - if all else fails, try Googling "Bunker Bash" :) Cheers, Roger.

Aha - I see what you mean - the coords didn't lock in on the original article - that's now rectified :)

I'm not convinced this sort of transient subjective information belongs in OSM. I appreciate you want to create a map for the event, and OSM provides some neat tools for doing that, but the place you have mapped is only going to exist as the 'bunker bash' for two days. It currently is some sort of event ground or field I assume, and afterwards it will go back to being that.

The grass tracks in the fields, yes, they'll be gone after the event, to reappear in a year for the next event, but the main track, which wasn't there to start with on the map, will remain - as will the buildings, which weren't plotted either. I think I know what you're going to suggest here, and follow the logic, but let's here a few more opinions, please :)

What's wrong with adding things that are emphemeral? We can just delete them again, later. At least it'd mean that the *history* of the map would be accurate -- surely something that, once we've mapped everything (ha!) will start to be of interest?
Not that I can personally be bothered mapping things that aren't pretty well fixed (I don't bother with 'building site' etc. for instance).
