BIURMAN, G. - Charta öfwer Wästmanland och Fierdhundra. Med Kongl. Maj.ts. nådigste privilegio utgifven af Kong:e Landtmäteri Contoiret. G. Biurman sculp.

A scarce map of the district of Västmanland in central Sweden, just north of Lake Mälaren. A large title cartouche upper left and a key in the lower left corner.
The map is a part of a work by Kongl. Landtmäteri Contoiret and its associates published in the years 1739-1793, covering parts of Sweden, Finland and the Baltic States. Engraved by Georg Biurman a Swedish engraver and mapmaker.
This was the first effort to map the country in somewhat uniform maps. The first map to be published in 1739, was the grand "Charta öfwer Mälaren" by Jacob Nordencreutz. The maps Upland, Västmanland, Södermanland, Nerike, Skåne and a general map of Sweden followed in the 1740s and early 1750s.
Few copies of these early maps were sold and the endeavor came to a halt due to economic difficulties. After some years, the next map to be published was the 1769 map of Medelpad. The remaining maps were then published during the next twenty-five years.
The last map "Charta öfver Heinola Höfdingedöme" was issued in 1793. Many parts of Sweden were never covered (Öland, Gotland, Halland, Herjedalen and Norrbotten). Since the project was unfinished, it was never sold as a proper atlas.

The few atlases that do exist are compilations. The general map of 1747 by Biurman is a milestone in Swedish cartography. It replaces Bureus1626 map as a blue print of Sweden for foreign cartographers. (In the mid 1790s Samuel Gustaf Hermelin launched a private attempt to map the country, this time with success. All of Sweden and Finland was mapped by 1818.
