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 675 sheets in the series and we are slowing georectifying them using the excellent Mapwarper We have most (all?) rectified. To help with the georectification please see MapWarper:

  • 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.
