Digitising and geo-referencing ancient, delicate tithe maps
The tithe maps were very large, ancient, delicate and in a poor condition. They were scanned on the largest scanner in the UK owned by the National Coal Board.
We received the enormous data files and our experienced cartographers then took the maps without location coordinates, image stitched them together in a digital format.
The cartographers used features such as historic buildings and landmarks – watercourses and the road networks, that were identifiable on both sets of mapping, and then “warped” the historic maps together. These could then be geo-referenced to OSGB data.
Where the historic maps contained no data, these were coloured to enable data from current maps to be visible.
Outline polygons of the title land parcels were also created on the base map, and associated with the apportionment data.

Digital catalogue of geotiff images
We delivered a digital catalogue of geotiff images to the client. This is now accessible on the Tracks in Time website where the two maps can be viewed side by side – zooming in to see current and historic detail.
The database can be searched using family names and the plots of land associated with that name can then be identified with their details.
