If you plan on having your property surveyed we recommend contacting a land surveyor or engineering company for information.
The Cadastral map portrays recent surveys that have been registered at the municipality involved. Chances are that the municipality holds information on surveys conducted prior to the digitalization of the Cadastral map. As for farmsteads, the most up-to-date information are in most cases old boundary descriptions made about a century ago. These are kept in books called “Landamerkjabækur” and can be accessed at the district commissioner, or online at Jarðavefur þjóðskjalasafnsins (only in Icelandic.)
