GeoDRM GIS Thoughts

GeoDRM data protection will it ever work ?

As I have noted before, OS is interested in GeoDRM activities as a way of standardising how rights to access information and the transfer of those rights between individuals and groups is standardised as much as possible.

Of course we also need to track developments in the more contentious area of data and IP protection techniques, and today I have been visiting some people who have a solution in this space.

As I expected, at the moment, this type of technology is not fit for purpose for geospatial data, not taking into the account the “spatial” nature of geographic information and imposing unacceptable restrictions on the users computer platform (windows & IE only just does not work anymore !!!)

This raises a more fundamental question in my mind, are such protective technologies really worth the effort, sure they reduce the perceived risk of data leakage in the mind of the data owner, but as DVD Jon has proved such systems can nearly always be broken. We don’t currently protect data in this way, and I would suggest continuing not to and relying on other legal means may be the best route forward.

BBC discovers Pictometry

click on pictometry

The BBC News IT show this week highlights some applications of pictometry imagery. You may not be able to play the video outside of the UK I’m afraid, but a great PR piece from Pictometry.

Interesting to see how imagery is used as an alternative to large scale topographic data where it is not available.. However.. there is massive as yet untapped potential for such imagery when it is combined with intelligent feature data, so that the user can find out what they are looking at without interpretation.

OS NPE Maps online and copyright free(ish) !

Old MapAs Steve points out, Richard Fairhurst’s scanned database of OS New Popular Edition Maps on the 1930’s and 1940’s in now online at www.npemap.org.uk.

Although the mapping is now out of copyright, Richard is claiming copyright over the scans and is licensing the data using the Creative Commons Attribution-NonCommercial 2.5 license.

This is a fascinating collection which provides a unique view of England 50 years ago, an England without Motorways, Aerodromes with Grass runways, and with an Ordnance Survey which was firmly a military institution.

There is huge potential for this data to form the basis of many applications which don’t require either up to date or very accurate mapping, and it will very interesting to see what develops.. Already the mapping is forming part of a tool to collect an open source geocoded postcode database.

The groundswell of community generated mapping continues…
