The ’proposals’ for John Rocque’s map asserted that the survey was done:

“by Trigonometrical and other Observations from the Tops of Steeples...; by taking the Angles at the Corners of Streets, &c with Proper Instruments, and measuring Distances by the Chain”

The map measures six and a half feet by thirteen; the scale is of 200 feet to the inch.
