Ireland British War Office 1:25k GSGS 3906
These sheets were created in 1940 by the British War office by photo-reducing 3rd edition 6inch (1:10560) sheets (~1910) and adding some contours.
There are about 650 sheets in the series and we are slowing georectifying them using the excellent Mapwarper We have about 200/650 sheets rectified so far. To help with the georectification please see the following page:
- TODO add link to GSGS 3906 georectification project page
Legibility is difficult in places due to the photo-reduction. However, these sheets are extremely valuable to OSM mappers as they give us the ability to accurately map townland boundaries when used in combination with Bing satellite imagery.

Richards & Company of Philadelphia, the Memorial Atlas of Ireland is a rare resource for researchers of Ireland at the turn of the 20th century, in that it presents in clear detail the boundaries of each barony and civil parish in the country--something not usually of focus in maps from the era.
