For some time people have been crying out for OS data to be made freely available, and on 1 April Ordnance Survey announced the release of a load of it.

On Monday Simon Whitehouse will be  sharing his thoughts and leading discussion on Ordnance Survey OpenData: eg implications for public bodies opening up their data and the new products that might be created.

From the horse’s mouth:

The government recently held a consultation on Policy options for geographic information from Ordnance Survey, the response to which was released just over a week ago.

I will be talking about the consultation and the implications of the response, especially for public bodies. This will include thoughts on the future of open public data in the UK.

I will also cover the Ordnance Survey OpenData site and if there is interest I’ll go through embedding a simple OS Map into a WordPress blog post.

It’s being held in Moseley Exchange at 6.30pm. The event is free to Moseley Exchange members and £3 on the door to non-members.

Anyone is welcome. If you intend to join us please take a moment to register on our Eventbrite page.

It’s quite an old tree, and clearly the footpath has been built around it:

Tree in the middle of the pavement on Pershore Road

I often wonder why it’s there. The trees are otherwise in a deliberate line, equally distanced, along the road. Suddenly this anomaly springs up, apparently after the road was built (it’s a similar age to the other trees) but before the footpath was laid.

But maybe it’s not as random as it looks. The photograph doesn’t show it, but in the playing field to the right is another tree which could be a continuation of the line started by the two in the forefront of the picture:

The blue line to the left in the image shows the line of trees along the road; the yellow line to the right shows the possible line of trees through the playing field

I’m guessing there must be a preservation order on the trees, because otherwise the police training centre (whose playing field it is) would surely have removed theirs.

The thing that fascinates me (presuming my hunch is correct) is the purpose of that second line of trees: did it mark something out, and – if so – what? It’s not perpendicular to the other so it can’t have been marking out a square grid; and there’s nothing to suggest what may have been there before.

I know, I should look at old records and plans and historical whatnot. Maybe I will.
