Goals

Staðfangaskrá, which is Icelandic for "access address", is a dataset of addresses in Iceland, constituting both GIS information (GPS location) and description (postal code etc). The data has been released by Þjóðskrá Íslands (Register Authority) under a Open Government Licence for public sector information.

The coverage of OpenStreetMap addresses in Iceland is of various quality, in the metropolitan area the coverage is pretty complete and in various smaller towns but others are completely missing. This dataset enables us to fill in the gaps.

In the cases of towns which already have buildings we add the address to the building (for example Hveragerði). In the case of no buildings being on the map (due to missing imagery and or missing data) the addresses are added as nodes (for example Akureyri).


Community support

I, (User:Stalfur), plan to do the import using the import account Staðfangaskrá import, and am an active member of the Icelandic OpenStreetMap community. The Icelandic OSM community was notified and had no objections thread detailing Akureyri import suggestion.

Schedule

They import will be run as appropriate, identifying areas lacking in addresses and tackling each one on its own.

Initial list:

  • Akureyri
  • Ísafjörður (partial)

Import Data

Data is refreshed daily at [1].


Background

Data Description

The register contains the following data columns: SVFN, LANDNR, HEINUM, MATSNR, FASTEIGNAHEITI, POSTNR, HEITI_NF, HEITI_TGF, HUSNR, BOKST, VIDSK, SERHEITI, DAGS_INN, DAGS_LEIDR, GAGNA_EIGN, TEG_HNIT, STADA, ATHUGASEMD, X, Y, HNIT.

We will use the location (X and Y), postal code (POSTNR), street name (HEITI_NF), house number (HUSRN) and building name (SERHEITI) where applicable.

OSM Data Files

Each postal code will be imported on its own as applicable - extracted from the main source.

Import Type

On a case by case basis each municipality will be evaluated for import. In the case of existing addresses then gaps will be identified and only those uploaded. In case of wholesale missing addresses an upload per postal code will be done.

JOSM upload will be used.

Data Preparation

Data Reduction & Simplification

The data is looked at for each postal code - possible duplicates with existing source removed.

Tagging Plans

OSM Tag Source Justification
addr:postcode POSTNR
addr:city knowledge
addr:street HEITI_NF
addr:housenumber HUSNR
addr:housename SERHEITI
