prize7-6, Exercise 3: Comparing old and new maps Model answer (method; the changes depend on your area): 1. Open the National Library of Scotland maps site, or the equivalent for your area, and choose a side-by-side or overlay view with an old Ordnance Survey sheet and a modern map. 2. Pick one square kilometre, such as your street and the streets around it, and note the date of the old sheet. 3. List five changes. Typical examples: a field replaced by housing; a railway line or station that has gone; a new road or bypass; a canal or pond filled in; a changed name or the loss of a farm. 4. Note anything that stayed the same, such as a church, a river course or an old boundary line. 5. Write one sentence on what the changes suggest about the history of the district. Tip: use the date on the sheet and say which edition you compared.
