How “U” shaped is your valley

Something that will either bring make warm memories or horror to people who studied Physical Geography at School is the creation of valley profiles, in particular to illustrate the erosional effect of glaciers in the recent Geological past..

OK, so that’s at least 50% of my readership which have clicked away.. the rest of you, welcome you are true geographers – be proud !!

Well now the process has become a little easier, a few weeks ago Google announced the latest extension to the Maps v3 API which provides programatic access to the underlying global terrain model used in Google Maps/Earth.

So now a profile across Snowdonia for example is easy..

From a techie point of view as well as the familiar  javascript API interface to this, there is also a RESTful web service API that provides output in JSON or simple XML.

A little perspective needed..

Who is watching who ?

It’s amazing how much copy a Lib-Dem MP on the run up to the general election can generate by calling up the press and mentioning street view in the UK has pictures of the “secretSAS base.

There is actually a serious and rather worrying point behind this nonsense, there seems to be evidence of an increasing number of  innocent photographers being interview by constables or any jobs-worth wearing a day-glow jacket, sighting anti-terrorist legislation which make taking pictures of public buildings a security threat.

This is from the country with the highest concentration of CCTV cameras in the world.

By the way, I won’t tell you whose building is behind the CCTV array (for the congestion charge actually) but if you watch the 1999 James Bond film, “The World is not Enough” you might just get a clue.

OS Consultation; a fairy tale ?

The past couple of months seems to have offered a cathartic opportunity for the relatively small UK Geographic Information Industry to get some long terms issues off its collective chest.

In no particular order we have seen the following public responses to the Consultation for the future of Ordnance Survey. (Let me know if  you know of any more.. updated – thanks for all the links, keep them coming)

All these responses share a common opinion that the status-quo or Ordnance Survey’s own strategy (remember that?)  for it’s future is not acceptable.

In many cases the responses quite rightly identify the issue as something wider than just should OS make some data free, but what is the UK strategy for the use of Geographic Information in general.

This strategic view is something which has never been defined clearly, but is something OS has unfortunately tried to remain gatekeeper for, as it’s Director General is advisor to Government on all things geographical.

The consultation understandably and in my mind quite rightly has remained focused on the specifics of making OS data free, and in the great tradition of Civil Service options papers offers a Goldilocks Choice; one too cold, one too hot and one option just about acceptable.

Option 1 appears to maintain the status-quo and I don’t see anyone outside the Romsey Road distortion field supporting it.

Option 2 is perhaps something that may be achievable in the long term with continued technological change and changing market requirements, however at the moment this would put Ordnance Survey in a position where it’s current operational processes are financially unsustainable.

So Option 3 represents the obvious compromise,  some small scale data for free while allowing the cash cow of MasterMap to continue to fund a reduced but largely similar OS to the one we have today.

There are of course two rather large Elephants in the room, one of which appears to have been put into the “too difficult” bucket and the other is not mentioned perhaps because by making data free the issue will disappear ?

Postal Geography, the fact there is no single address register which can be used without major limitations is a national embarrassment, for a knowledge economy this is the equivalent of trying to run railways before a single standard time was introduced.   This is an issue bigger than Ordnance Survey, although OS has had it’s part to play in the current mess, this really does need strategic leadership from the centre.

Derived Data, OS must stop its current practice of claiming intellectual property rights to any geospatial product created with even passing reference to Ordnance Survey products as “derived” information. There is no direct mention of this is the consultation, and if OS data is made available using a CC-BY license then this may not be an issue, but I would really like to see this clarified.

I just can’t help thinking however them is a dreamlike / fairy tale element to this process, Goldilocks aside.  The consultation process ends today, and Government will probably shut down and enter Purdah in 2 weeks, I just hope we don’t wake up after the election and find the whole process was a dream and the new administration has much bigger issues to deal with.
