Christopher Greenwood (1786-1855) was a surveyor from Wakefield, Yorkshire and moved to London in 1818. His brother John was also a surveyor and in 1821 they joined forces and with the distribution capabilities of George Pringle and Son, made an immediate impact with their series of large scale surveys of many English counties. The early 1800s was a time of rapid change in the landscape with the burgeoning industrial revolution. Their surveys utilised the latest system of triangulation adopted by Colonel Mudge and his surveyors for the Ordnance Survey. Indeed they were in open competition with them. This is one of four published by the brothers in 1825, despite being uncoloured it is in its preferred loose sheet form, un-dissected and complete with imprints outside the borders. It is engraved in large scale at one inch to the mile and differentiates between woods, heaths and commons, parks and pleasure grounds, different types of waterway and roads. Watermills and windmills are identified indicating their significance to the local economy. A large vignette of Bury St. Edmunds occupies the lower left corner. A fine large scale map of the county in loose sheets. Rodger (1972) no. 445.
