Meän sauna : Inventory of old smoke saunas in the Torne river valley using laser scanning and photogrammetry

MEÄN SAUNA - Inventory of old smoke saunas in the Swedish Torne river valley using laser scanning and photogrammetry. The cultural heritage of the Swedish Torne river valley has been dominated by the Finns. A strong manifestation of this are the numerous smoke saunas on the area. Due to the Lapland war in 1944- 45 the building stock as well as saunas where largely destroyed in Northern Finland. The smoke saunas in the Swedish side were left untouched and are representing the historical type of Finnish sauna culture and sauna buildings in Torne river valley and Lapland. Every time a smoke sauna is warmed up there is a risk of fire, especially with old saunas. In Torne river valley there is a strong risk of cultural heritage vanishing, since no inventory of these saunas has been done on Swedish side. In Project MEÄN SAUNA selected old smoke saunas in Swedish Torne river valley will be inventoried by researching of history, laser scanning and photogrammetry. 3D models of sauna buildings will be created and saunas will be classified. The lecture will present at least two old smoke saunas of which one is from 1720. Presentation will contain a brief historical background of saunas as well as explanation and photographs of the site. The methods for laser-scanning and photogrammetry measuring method will be explained. The smoke saunas buildings will be presented by photography, laser-scanning and technical drawings. At the lecture live use of computers and program will be displayed, to make it possible to discover the saunas within the 3D models.
