The National Library of Scotland has published some wonderful maps (120,000 of them) which give great street-level detail over a number of years. I've spent a number of happy hours going through these and I include this resource on this blog as using these maps can not only pinpoint home addresses for soldier ancestors but also identify where a man fought.
In the images above, from the top, we see a map of Ypres in June 1917, then a satellite view of Ypres today, and finally a combination of the two. It's really very clever. Go and play.
I offer a fast, efficient and cost-effective military research service. Have a look at my military research page and drop me a line if you think I might be able to help.
