Ordnance Survey Thoughts

Unlike LOST, the derived data saga continues

Not 300m from the site of one end of William Roy’s original baseline for the first Ordnance Survey of Great Britain, the modern Ordnance Survey yesterday held it’s annual business partner conference.

Well for me it was a strange experience, sitting in the audience at an Ordnance Survey partner event (although Google is not a partner) just a few months after it seems the world fell apart around the directors of the OS – talk about a LOST style flash sideways.

It became clear soon into Vanessa Lawrence’s presentation that the organisation is still recovering from these traumatic events, and that there is not a vision yet for the future of an OS that both produces commercial and free data sets.

OS Lost at Sea ?

There were 3 key aspects to the keynote;

  • The release of the free data was as many  suspected  forced upon the OS, and there is still some internal resistance to the whole idea at the top of the organisation.
  • The building of the new OS Head Office is going according to plan, although it always seems to rain when Vanessa is onsite !
  • The Queen will be opening the new building (Did I say the building was on time)

Key issues for the partner community in terms of complex pricing and licensing models remain, work on solving those has been delayed it appears as a result of all the “free data” nonsense, although a new more simple model is promised in the future.

The big issue of derived data also remains, although to his credit in the Q&A session, Peter ter Haar aimed to clarify things by reading out from his iPad a draft version of what OS view is derived data. This it is promised will also be released soon, but to paraphrase;

Derived data concerns the direct copying and manipulation of features which exist within an OS data product. If new data which does not appear within the OS data is captured with reference to OS data, then this data is inferred, not derived, so it’s OK !

Of course the free OS data has no “derived data” limitations..

I asked for the OS to communicate this on their website as some form of White paper, again we await this with interest.

Of interest clearly to OS partners in addition to pricing and licensing and the future role of OS Ltd, which was only briefly mentioned are products..

Here the OS seems to be making real progress the new VectorMap series is at last demonstrating the capability of the OS to produce products that are fit for purpose for electronic rather than paper mapping, John Carpenter delivered an excellent presentation on these new data products and the philosophy behind them, this truly was a breath of fresh air.

Clearly it has been a difficult year for the OS, the landscape has changed massively and continues to do so, Vanessa hinted that the new government spending cuts have already started to have a impact, perhaps as Thierry is suggesting a reduction in the subsidy promised to deliver free mapping?

More than ever the OS needs a new vision fit for such a radically changing environment, embracing the freemium model which has been imposed on them and establishing their role within a very different UK and global geospatial industry.

The new building deserves a new vision ?

Zeitgeist – words of wisdom..

Last week I attended the Google Zeitgeist event, a kind of mini-TED the highlights of which are in the video. I’m the one with 8 screens of Google Earth goodness,  and after a ride I’m saving up for the Tesla !

Like the map, can you make it less visible ?

As a Geographer and map geek one of the hardest lessons I have learnt, and what many in the web mapping field still need to learn is…

Eds law of mashups..

“The map is important, but not as important as the data you are publishing on top of it”

Yes the expensively created, well drafted work of art you have struggled to produce following years of effort, is actually just providing a background or context to the location of pizza restaurants or free car parking places.

You might not like that, but is true !

A number of web mapping companies have over the last few years experimented with a few different colour pallet tile sets, but last week rather buried by the other Google I/O announcements, the latest enhancements to the v3 Google Maps API was announced in the form of  “Styled Maps“.

Rather than just present a few fixed tile sets, styled maps allow you to dynamically create a map based on a custom colour palette so there is a huge range of possible map styles available to you.

Styled maps may be used to;

  • Make the background map less intrusive..
  • Conform to a website design, A orange map for easyjet ?
  • Make some features “invisible”, – remove minor roads for example !

So this is not a full computer cartography tool yet, but these enhancements we meet the needs of many map developers to make their maps unique.

Those in the know will realise this represents a whole new way of rendering maps online, the definition of a “map style” is stored as JSON matching map feature types to styles defined by  hue, lightness, saturation, gamma, inverse_lightness and visibility.

To make life a little easier there is a rather neat web tool to define your styles.

Remember one day, no two Google maps will be the same…
