Skills Session - Map Regression

Join James Jarvis to learn about map regression as part of the Dunkeld Archaeology and History Club.

Map regression is the process of working backwards from modern maps to earlier maps of the same area, to determine change or to locate past features. The process is mainly used in research on the history of places.

Comparing maps of a chosen area compiled in different periods can help reconstruct the chronology of events which have altered the natural or built environment. In archaeology, map regression can help to locate features appearing only on earlier maps and to assign building phases. It is often part of desk-based assessments before fieldwork is undertaken.
