In addition, SABRE Maps provides free access to OS mapping from the end of World War 1 to the 1970s at small and intermediate scale mapping, including 1:25000, One Inch, Half Inch, Quarter Inch and Ten Mile scales, usually with a wider coverage of individual revisions than the NLS. [71]
After 1854, the six-inch maps and their revisions were based on the twenty-five inch maps. The six-inch sheets covered an area of six by four miles on the ground; the twenty-five inch sheets an area of one by one and a half. One square inch on the twenty-five inch maps was roughly equal to an acre on the ground.
The maps were published at one inch to the mile (1:63,360) using the Ordnance Survey One Inch 'Popular Edition' (the 4th Edition) as the base. Publication of maps and reports began in 1933 and was completed in 1948 after interruption by World War II, though sheets were published in every year from 1933 to 1948 with the exception of 1941 (Stamp ...

The OpenHistoricalMap community has organized projects to map certain historical periods and themes in detail. Major contributions have included: Historical boundaries of U.S. states, imported from the Atlas of Historical County Boundaries, a project of the William M.

[6] [7] This survey at a scale of 1 inch to 1000 yards (1:36,000) [8] was the starting point of the Principal Triangulation of Great Britain (1783–1853), and led to the creation of the Ordnance Survey itself; work was begun in earnest in 1790, when the Board of Ordnance began a national military survey at one-inch-to-the-mile (1:63,360 scale ...
