Hliðskjálf, a society for open and free geographic information data was founded October 24th 2013 in Kópavogur, Iceland (registration number 541113-0880).

The society agitates for existing GIS data to be made public under permissive licenses where possible. It also aims to create an inventory pointing to such data in Iceland, and possibly for other countries or areas.

It is an enthusiastic supporter of OpenStreetMap and similar open and free data initiatives. To that end it has several projects ongoing in Iceland and one in Africa, Mapping Botswana.

The name Hliðskjálf comes from Norse Mythology where it was the throne of Odin from where he could see all of earth and happenings there.
