OS women and the Allied war effort 

We’re proud of our long heritage at Ordnance Survey (OS) and that our teams contributed to the war efforts in the 20th Century. We have a memorial at head office commemorating the 123 people who lost their lives from OS during both world wars and gather each year to remember them. We supported the war efforts in many ways, including printing 33 million maps to show trench positions during World War One.
