Free Our Data: the blog

A Guardian Technology campaign for free public access to data about the UK and its citizens

Norwegian mapping authority frees up maps

Oh, those crazy Norwegians. They’re giving away maps for free. Within limits – it’s limited to “individuals and non-profit associations”. So that’s half a step towards free data.

Interesting that this is also including maritime information – the stuff that the UK Hydrographic Office sort-of provides; it’s rumoured to be on the list for privatisation, however.

And of course Norway was one of the countries in the OS’s woeful International Comparison report. Apparently it gets an unknown amount of government grant, but operates a “full cost recovery” system (6.1.4 in the report).

Arguably this is similar to the OS’s OpenSpace project, which is free-ish availability of data for individuals and non-profits… as long as they don’t get too big. What’s not clear in the Norwegian example is what its rules on “derived data” are. That would be interesting to know from any Norwegians.

From this Google translation page of the Associated Press story in Norwegian:

(AP) Soon, you can use much of the information at the Norwegian Mapping Authority on your private website, and take up battle with Google Maps.

From 1 December this year, you can retrieve detailed information from the Norwegian Mapping Authority, and bake it into your own web pages. Totally free, if you are an individual or operate a non-profit association.

It follows the Norwegian Mapping Authority in the footsteps of Google and the Norwegian Meteorological Institute, who shares the information it holds on to the free public use.

There is talk of detailed maps and geographic information that the Norwegian Mapping Authority has been sitting for a long time, and that until now only been available for those willing to pay.

“The data has been available through the programs that we manage, but now it will therefore be direct access to the service,” explains Erland Røed the Norwegian Mapping Authority to VG Nett.

Like for example, Google’s maps will be extended the opportunity to mix together information from several sources, and then add this on top of the map from the Norwegian Mapping Authority.

You should read the whole page (so I’m not going to copy it all here). But it does sound like the Norwegian Authority is getting with the program in a big way.

….At the State Map Verks web pages, users can decide how utstnittet of the map should look like, the layers of information to be included and finally get a clip of code.

…The system located at the bottom of the State Map Verks solutions [is] also at the forefront of the development of open software.

“Operating systems and databases we use are free software, so this is done by the book. It’s gone out 80 million map images of this year, says Røed. “The public and private individuals who have gone on our site has generated a lot of use before it is released freely, “he says.

By releasing data free on the way the Norwegian Mapping Authority do hope that the users themselves to come up with good solutions. A few examples of how users can generate more information from the maps of the Norwegian Mapping Authority is sports.

See chart to the Norwegian Mapping Authority, for example, be used as background during a real-time tracking of Færderseilasen with all available information as a true marine gear.

Such tracking is technically possible even with the Google service Google Maps, but without details that a real chart can offer.At the State Map Verks map is the depth measurements, lighthouses, beacons and all the relevant information for sailors, where Google Maps only shows the blue sea.

Similarly shows the topographical maps of the Norwegian Mapping Authority highly detailed rendering of the terrain, long more accurate than Google Maps.

There is also a reader discussion of site boundaries, which has a translation too.
