In addition to large-scale general maps, small-scale town, village, estate and district maps were made following the foundation of the National Land Survey. Maps were chiefly made for taxation purposes. This first generation of local maps are maps for country assessor's records. Apart from map drawings proper surveyors would also determine on the map what the taxation figures for each house were. From the 1640s onwards each province in Finland had its own surveyor. In the early stage the most densely populated regions in the administrative districts of Turku and Pori, Uusimaa, Häme, Savo and Karelia were mapped. In the early stages of this work surveyors had little time to visit far-flung Central Finland.
