The occupation of Finland and the Great Hate ended the mapping of Central Finland, which had begun so promisingly. But relatively quickly after the peace of Uusikaupunki (1721) work was resumed. In 1725 the surveyors of the area were Johan Vettervik in Keuruu and Adam Giöker in Laukaa, making maps of areas which had been included on maps before. In the same year Vettervik made maps of the estates of Sinervämäki in Multia. Local maps worth mentioning also include the maps of Niemisjärvi in Hankasalmi (1734), Jyväskylä (1734), Leppävesi in Laukaa (1734) and Sumiainen (1734). During the following decades maps were made of most villages and houses. The oldest map of the town of Jyväskylä dates from 1833, the year when the town was founded.
