Maps Kidnapped ?

DRG's are free !!

As both James and Jo blogged, the complete series of USGS Quad series DRG maps were taken hostage this week and then released following the payment of $1600 to the Free the Maps website.

Now we are thought the data was free right? – well yes but.. Some states made the data available free to download, some commerical operators charge for media (with some mark-up), most of the data is available on sites like Microsoft Terraserver. However as the site explains..

“..Because there are so many different web sites hosting bits and pieces of this data, it is often difficult to find.

When you do find it, there is often missing data, the files are difficult to download, or the site may use non-standard naming conventions for the files. In addition, there are still a significant number of States that have no DRG’s available for free download.”

So $1600 later all the data has been purchased and will now be uploaded to the Internet Archive. Great job Jared !!!

Unlike Jo (no surprise there then :-)), I don’t think this is the model for future funding for European Mapping agencies whose data is currently protected by copyright… but it may well form the model for exploiting and distributing OS maps as they reach the end of their copyright as the mapping will be of similar age.

The example DRG above is 35 years old, and out of copyright OS mapping is 50 years old.

Autodesk and the big opportunity..

Pete Southwood

I had a real flashback from the past when I received an email from Autodesk, inviting me to join in on a webcast to be presented by an old colleague and ex-pat Brit, Pete Southwood on MapGuide Enterprise. Despite a financially poor period a result of a downturn in the core AEC market ?, Autodesk is once again making a impact in the GIS market.

Autodesks support of OSGeo and the release of the Open Source version of MapGuide have got people talking about Autodesk again, and clearly Map 3D 2007 remains a strong data capture tool, but… and its a big but, the issue of CAD / GIS integration still remains a problem for many organisations and customers of Autodesk.

I would argue that most geospatial data actually resides today as design data held in DWG and DGN files not in GIS file formats let alone geospatial databases.

So there remains an opportunity for Autodesk to finally begin to migrate this data using their tools – perhaps the innovation which results from the open source development around MapGuide may provide some clues to opening up this difficult to crack market.

When I was involved with MapGuide at Autodesk, I often argued with anyone who would listen, that MapGuide had the makings of a excellent server of geospatial drawing data for AutoCAD Map clients – at the time there was never the engineering resource available to do it, of course today, there is a whole community of skilled developers looking for the challenge.

Copyright free mapping is coming..

Like a spurned lover, I was beginning to feel neglected having been ignored last week by the Guardian’s “Free our Data Campaign”, but this week we are back to normal with a piece describing the efforts of the OpenStreetMap team to Map the Isle of Wight last weekend.

In the past I have made it clear that I am fully behind the efforts of Steve Coast and the OpenStreetMap movement to create copyright free mapping, the technology is here today and with some bright people and organisation it is completely practical to produce a national street database for Great Britain.

As Jeff points out in his blog, National Mapping Agencies such as the OS need to wake up to these community driven developments, however I really think we must see them not as a threat, but as an opportunity.

Will Steve Coast be the Linus Torvalds of open source geodata ? time will tell, but I believe OpenStreetMap is every-bit as important a development in Geospatial data as the development of the Linux Kernel was for operating systems, and I suggest ultimately a similar commercial model may develop around open source geospatial data.

There is without question a place for open source “small” scale data, without the high spatial resolution, rich data models and high levels of currency which characterise products like OS MasterMap.

Open Source geospatial data products will meet the needs of many users who just need to be able to produce simple location maps and which need to be updated less frequently. But even these maps will need to be updated..

Keeping such datasets up to date, is a lot more difficult but potentially possible.. however it may need a more robust long term funding stream to support the process, keeping servers running and bandwidth costs real money.

This does boil down ultimately to the old “Free as in Speech” or ‘Free as in Beer” debate, copyright free or open source mapping may well ultimately migrate to the former position – copyright free but commerical supported in some way, this I think is still very positive for the Gi Industry, with many opportunities for commercial support and value add services.

Such a “free as in Speech” dataset supported by a robust commercial model may well meet the needs of the user community, but I not sure it will go far enough for the “free our data’ campaign which is more politically motivated.

In conclusion we must recognise that open source geodata is here to stay and is real, Mapping Agencies such as the OS must learn to adopt it’s values and meet the needs of a user community not fully served today.

Actually I really do see a role for the OS in contributing to open source databases in the future, copyright free street maps are a great starting point, but it would be great to have urban area boundaries and a coastline, for example, contributed by the OS?

btw – I appreciate the efforts of guys last weekend to make sure they were not using “in-copyright” maps of the Isle of Wight, but I think the Map of Namibia used by the guys in the articles photograph is taking things a bit too far !!
