Swedish Large-scale mapping Historical Maps,

Ancient Remains GIS database In 1628, the King Gustaf II Adolf gave instruction to Andreas Buréus to large-scale maps over all & farms and showing all their “...fields, other data in meadows, woods and land” of the realm Also , mines, harbours etc… Landscape Analysis This is the start of The Swedish National Land Survey, Lantmäteriverket. Gustaf Svedjemo Geographical mapping = Small scale maps (> 1:10 000) Gotland University Geometrical mapping = Large scale maps (< 1:10 000) [email protected] Footnote: Andreas Buréus cousin, Johannes Buréus was the first director-general of the Central Board of National Antiquities (1609) and teacher to The King Gustaf II Adolf.

The start Map & text (Code marking) - Geometrical 1630 - 1655 & 1670’s - 1750’s

At first the main purpose of the mapping was to gain insight of the realms resources and later also: Sweden had been successful in wars and large areas were incorporated into the realm King Karl XI’s reduction of the nobles land; villages and farms came under the Crown Fiscal reasons were also prominent. 1. New Barquara 2. Sowing 18 barrels 3. Sowing 18 barrels 4. Sowing for hassle 5 ¼ barrel. In all fields is there clay soil mixed with sand 5. Meadow together counted on both sides of the river, on average Areas in present day Baltic states, Russia and growth it yields 166 (wagon) loads Germany was also mapped 6.

New tasks Storskiftes map over a farm on Gotland 1821… -Land Redistribution

Lagging some decades behind England, Holland and other European , Sweden in 1749 got its first modern act of redistribution of land Storskiftesförordningen Purpose: Redistribute land so farming could be more efficient Each farms land had been split in very many small parcels scattered over the entire village area

Act of Enskifte Act of Laga Skifte - The redistribution act of 1809 - replaces the Enskifte act 1827 – 1972

Huge social consequences for the Swedish side. The villages where split up and replaced by solitary farms The most informative and best maps ever produced in Sweden Scale normally 1:4 000 Purpose Every farm should have all land Redistribute the land of a farm to as few lots as possible, for concentrated to one single lot. efficient farming To strict for most of the country The farmer was no longer to take decisions in consensus with Few village was redistributed under the other farmers in the village this act The farmer was “King in his realm”, free to innovate

4 Lagaskiftes map over Uggarde Gotland What was mapped?

Since the mapping reasons mainly where economic in some sense, the features mapped where important economic features. Infields (fields & meadows) But also: Real action Woods Co-ownership Grassing land Prominent ancient remains Mills (saw & flour) Tax commodities Fishing hamlets Different constraints Seal hunting places Owners and leasers Building sites Ways of acquisition Etc, etc Etc, etc.

Very often the maps also contain information of great value today, which was not purposely mapped by the surveyor. One example is ancient remains visible as pieces of non-productive land in the fields.

Town maps The Gotlandic Maps of 1693-1703 1748

Gotland was first mapped in large scale with the maps produced by 7 surveyors between 1693-1703 These maps are unique in the sense that all farms on the entire Island were mapped and also the of Visby, since no Nobility owned land exists there.

5 Map & Text The Maps

Fair copy The scale is 1:8 000 Made with triangulation without any geodetic references, which lead to an uneven distribution of errors. Original text Remarkably good precision within smaller areas, but larger errors between areas.

The Swedish National Heritage Board Ancient Remains Surveys

FMIS The methodology (ASIS) Primary survey 1937-1974 Systematic surveying of all known ancient remains visible The Swedish National Heritage Board above ground To be recorded on the new Economic maps ArchaeologicalSites Information System Started on Gotland Field surveying and interviews with local people Purpose: To protect the ancient remains Service an information for community planning and cultural heritage management

6 Secondary survey 1974 - 2002 Ortho photo maps

Revision of the economic maps Urbanisation and rapid development of the Swedish society Non-field survey of archives Central archives, museums, excavation reports etc. Revisit to already registered remains Not unusual that they could not be recovered Historical maps Registered on Ortho photo maps Each surveyor did around 1-2 km2 per day

7 Problems & Limitations Village sites in Småland

Irregular surveying Different number of surveys in different areas Surveyors had different specialities 1980/99 Surveyors had different level of attainment County of Jönköpings Knowledge change over time 1974/80 Different priorities at different times and

geographical areas 1993/2002 County of Kalmar

The Archaeological Sites system is only the tip of an uneven iceberg County of Kronobergs

The Christianisation of Gotland The Christianisation of Gotland (continued) Basic data Research question: Farmsteads Medieval churches Parish borders Who took the initiative to erect the parish churches and around 1700 decide where it should be placed. A single “chief” or all farmers?

Hypothesis: The zero hypothesis was that the physical location of the church was a joint decision by the farmers and it was placed as “fair” as possible, which means that it should have a central location, in relation to all of the farmsteads
