Streetlist and housenumber evaluations for whole Iceland

On SOTM-EU in Karlsruhe a few weeks ago, a german OSM-Mapper asked for housenumber evaluations about Iceland.

I asked a heavy active OSM mapper in Reykjavik (OSM name: Kjarrval), if he could find out, if a countrywide streetlist or housenumber list would be available from iceland government.

Data Source

After a very short time, he was able to give a positive answer: the Statistics Iceland Government offers a countrywide housenumber list with a relative open license. A little bad news: the license is open enough for the evaluation of osm data, but the housenumbers (including geocoodinates) can’t be imported directly.

Missing administrative boundaries, artifical calculated

Unfortunately, the administrative boundaries for the iceland municpalities are very incomplete in OSM. They would be available for import, but up to now, they aren’t.

I decided to use the housenumber list above, which have geocoordinates for every address, to calculate artifical admin boundaries, because i need boundaries for my evaluations. On the SOTM-EU, i provided a brief overview for this method in my presentation slides, downable at SOTM-EU Page on the lecture. At the bottom, download ‘Presentation slides’ and look at Extension 2, starting at page 28.

The calculated boundaries will not be imported into OSM, of course, they will just be imported in my evaluation database, where i usually store a copy of the boundaries from OSM database.

Streetlist evaluation for Iceland

I finished the coding for import at 28.06. and was able to make a first evaluation. The structured view of the municipalities can be viewed at or have a look at the graphical overview.

The first evaluation showed, that the most relative official streets in OSM are in

1. Hafnarfjarðarkaupstaður (86%) with 280 of 323 streets,

2. Reykjavíkurborg (83%) with 911 of 1088 streets,

3. Akraneskaupstaður (82%) with 87 of 106 streets,

and unfortunately with 7 muncipalities, which have not one named street from the official streetlist.

Housenumber evaluation for Iceland

The first evaluation was calculated at 27.06. and i posted the first result for every municipality in the german OSM Forum.

The best 4 municipalities with most relative addresses are:

1. Seltjarnarnesbær (86%) with 845 of 975 addresses,

2. Sveitarfélagið Ölfus (79%) with 552 of 698 addresses,

3. Hafnarfjarðarkaupstaður (77%) with 4220 of 5460 addresses,

4. Reykjavíkurborg (77%) with 16184 of 20838 addresses.

The table oriented evaluations are available (scroll down to Ísland), for the graphical overview first go the table oriented evaluation of the muncipality and click on the result page at the very top at ‘grafische Anzeige’. Sorry for this indirect link, i work on a better integration into the graphical overview at. For example, have a look at Reykjavíkurborg.

Open Issues for Iceland evaluations

Up to now, i have only made one single test for correct sorting of the iceland special characters. I work on it.

The most important issue is to support english language to the housenumber evaluation. I will start on this issue next and hope to have a first version in two weeks from now on.
