@holy-cow Sweden was mapped starting 1628 when the The Swedish Mapping, Cadastral and Land Registration Authority was formed. They did a fantastic job detailing all villages and surroundig areas down to sub acre size and noting the corresponding land use. The aim of the king Gustaf II Adolf was to figure out the potential production capacity in the country, mainly for warfare purposes. Wiki Lantmäteriet - Wikipedia Natural borders are common. After generations of splitting farm land inhereted by relatives there was a reform 1800 something aiming to make farming easier. On some areas properties could be 3000m long and 10 m wide as land was divide from hill down to valley.
Anyhow these old surveyors did the job very well and a lot of these boundary lines are still in use in areas where nothing has changed. This creates a bit of a problem when ancient surveys meet the new ones. Sometimes the error can be several meters. Markings on site is what counts, not the maps irrespective of date. Sometimes the case is that stones have been moved +200 years ago by local agreement without telling authorities.
New residential areas usually have properties close to rectangular shape but no PLSS system. Only the The Swedish Mapping, Cadastral and Land Registration Authority can set out new property poles, no contractors.
This is a more recent approach to what was already done +300 years ago. CadasterENV Sweden A multi-scale and multi-purpose land cover monitoring system (swedishepa.se)
