OSGIS 2011 Round-up

Woefully out of date now, here’s a quick run down on the OSGIS 2011 conference, 3rd in that series, held at the University of Nottingham Centre for Geospatial Sciences in Nottingham over the 21st and 22nd of June.

The 21st was a day of workshops, under the banner of Interoperability and the OGC. My new colleague, Matt, and I did a workshop on using Ordnance Survey Open Data and Mastermap with Mapserver and PostgreSQL, using the OSGeo Live DVD. You can see a slightly edited version of the workshop below, or on slideshare. I have to admit that most of the kudos must go to Matt for creating some super scripts to make the initial data processing *much* easier, and to some of my other colleagues for their efforts in styling the data once it’s in Mapserver. The scripts and a small subset of the open data are available here- you’ll have to supply your own Mastermap!

Day Two was all about the talks- and I was impressed by the standard. The focus of OSGIS has always leant slightly towards the academic, so the stand-out talks for me were the ones that demonstrated that you can do real spatial analysis with open source GIS. There were also some very good papers on mapping in the developing world. Two of my ex-colleagues from Oxford Archaeology also did a joint paper showing how the use of open source software has progressed there- that was really good to see- it was nice to know that the baton had been passed on when I left! I gave people an introduction to the OSGeo:UK local chapter, which is also available on Slideshare here, and we had the chapter AGM. It’s extremely gratifying to see the numbers of people willing to hear about, and get involved with, the local chapter. I was going back through the reports I’d given in previous years, and the numbers of people signed up to our mailing list steadily creep up, year on year- we’re now well over the 100 people mark! (BTW, if you’re interested, our website is here).

All in all it was a really good couple of days. Next year the conference will be running from the 4th to the 5th of September, so for anyone that can’t make FOSS4G and wants to give OSGIS a try, now’s your chance!

 

QGIS gets a Mastermap Loader (or: why open source is so cool)

A short case study into flexibility, collaboration, and why open source software is so damned cool:

At my new place of employment, we’re doing a lot of work with Ordnance Survey Mastermap data, so one of my colleagues built a quick python wrapper around the ogr2ogr script to easily pop the data into postgresql, or shape file, or whatever support format you like. This is now available on Github (caveat- it doesn’t do change-only updates yet- we’ll keep you posted on that). After a chance comment on the OSGeo:UK mailing list, our friends at Faunalia, who do great things with Quantum GIS, ported the code into a QGIS plugin.

So- in the space of one week, QGIS gained itself a Mastermap loader, through a simple bit of collaboration. Nice work guys! (Nothing to do with me, I was on holiday). Can you get that sort of flexibility, rapidity and collaboration with (insert your favourite proprietary package here)? I doubt it…

Ooh, we’re getting all digital now

So, we Brits are getting all excited because the Prime Minister gave a big speech about how Britain is going to be all fab,  broadbandy, and “totally, like Web 2.0, man”  soon. And all this data is going to be given away- look here’s some of it now. We’re all going to have instant access to Government services, free Ordnance Survey data, and a shiny Institute of Web Science to stick all the bits together.

Now, of course it’s a total coincidence that this is a nice positive announcement, and there’s to be an election shortly, for which we don’t yet know the date. Let’s not go there, since this is not a political blog. Let’s also not contrast this with the Digital Economy Bill, fast-tracking it’s way through parliament on somewhat dodgy grounds as we speak, that threatens to take a lot of this nice shiny stuff away if you’re so much as caught within a mile of an mp3 that you didn’t buy from ITunes. Let’s not talk about carrots and sticks, or nice cops and nasty cops or other such comparisons.

Instead, let’s concentrate on the data.  They will, on April 1st, release “a substantial package of information held by ordnance survey freely available to the public, without restrictions on re-use”. The consultation only finished 5 days ago! How can they possibly have had time to analyse the consultation responses yet? Personally, while I look forward to the release of the data, and it is a massive win for the Free Our Data campaign, I would prefer that they gave the consultation responses some respect by analysing them in detail, or at least pretended to read them properly.  I told someone off for assuming that the decision had already been made, and that the consultation was a waste of time, but perhaps they were right.

The rest of it, I quite like, though I’m yet to see a Government IT project really work properly. We’ve got (amongst other things):

  • “core reference datasets that contain the precise names and co-ordinates of all 350 thousand bus stops, railway stations and airports in Britain”
  • “an inventory of all non-personal datasets held by departments and arms-length bodies – a “domesday book” for the 21st century”
  • “information on each set of data including its size, source, format, content, timeliness, cost and quality”

All sounds good. I could get excited by this, but I just want to wait and see what happens, shall we, and not take our eye off the other balls?

On freeing data, unwillingly

So 10 days ago now, the UK Government announced that they would be freeing up some Ordnance Survey data as part of a “drive to improve transparency”. You can read reactions to this all over the geospatial blogs (see Mapperz excellent round-up), some ambivalent, others mostly positive.

Me, I’m with the ambivalent crowd. On one level, assuming it’s actually useful datasets made available, and assuming we get to use them how we’d like to (using it in our internal GIS, for example), it will be great, and my colleagues will find their jobs considerably easier. However, like a lot of things the UK Government has done recently, this was handled badly (the lack of Ordnance Survey input into the original announcement,  speaks volumes). If it’s not going to be done willingly, will we see the same quality? The same commitment to survey the rural areas? Presumably, the cost of the remaining datasets will go up to cover the projected loss of revenue (whatever that is), so a lot of small businesses could end up in a worse situation than they are now- with expensive data that they can’t afford, or free data that’s not fit for purpose because it’s not complete or recently updated. Like Peter Batty, I don’t want our data brought in line with that of the US, as it’s currently much better!

I’m glad there has been a change, as I broadly support the Free Our Data campaign, and have done since it started, but I wanted it to be well thought through and planned for, and not a snap decision to try and win some votes. How naive of me…

I’m also concerned, like Peter Batty, about the affect on OpenStreetMap. I’ve been an enthusiastic convert to the benefits of OSM, since hearing of Muki Haklay’s completeness studies, and with seeing some of the beautiful maps and really cool innovations that it has spawned recently. At conferences in the UK this year OSM felt like the juggernaut it was impossible to ignore, and why would you want to?  OSM is now a valuable part of the UK geospatial ecosystem and I would hate to see that change.
