KARTOR ÖVER KEMI & TORNE LAPPMARKER 1642 OCH 1643 
he lack of practical maps of the country's northern parts became an issue in sixteenth and seventeenth century Sweden due to boundary disputes of the time. The early maps of northern areas were rather broad-minded and even misleading making it impossible to calculate demarcations using these maps. In 1603 Carl IX issued an order to make a map of the northern kingdoms. The discovery of natural riches from the fell region of Nasa in 1635 speeded up the surveying of Lapland.

The first map of Northern Scandinavia by Anders Bure in 1611 depicts the lakes and river network of the area in a comprehensible way. Bure’s great and final map of the northern kingdoms in 1626 long remained as a model and basis for maps representing the Nordic countries. It is unclear whether Bure had visited Lapland, but Olof Tresk made several trips to Lapland during the period 1635-1643.


Olof Tresk’s charted findings had been forgotten for centuries. It is not known whether or not these maps have been used for practical purposes or indeed whether they influenced the development of cartography. In fact, the maps were only first mentioned in literature as late as the early twentieth century. Johannes Schefferus, professor of the University of Uppsala was familiar with the maps of Tresk and used them as his sources for his book Lapponia (1673), even though he copied Bure’s map in his book. The further information on Lapland provided with the maps remained a secret retained by Sweden's military powers and the National Land Survey.


Olof Tresk (deceased 1645) resided in Helsingland and his year of birth is unknown. Larsson is also mentioned as his surname. Olof’s brother Anders Larsson Tresk served as a magistrate in Hudiksvall. Olof Tresk was mostly likely registered with the University of Uppsala in 1625 using the name Olaus Laurentii Helsingus. Later, Andre Bure appointed Tresk as a land surveyor and his immediate task was to survey the area around the silver mine of Nasa including the fell ridge in the north. Tresk lived the life of a travelling surveyor right up to his demise in 1645 and indeed complained in his letters to the his superiors at the National Land Survey that he lacks permanent domicile or decent apartment. The tough way of life took its toll on Tresk’s health. His death in 1645 was decades earlier than his elder brother Anders who passed away in 1688.
