 The Greenwoods' intention was for a series of maps of the whole country at a one-inch scale.They did not achieve this, largely because of competition from the newly founded Ordnance Survey, but their output includes superb maps that were finely drafted and elegantly engraved.Between 1817 and 1830 they produced a series of splendid large-scale folding maps of most of the counties based on their own surveys.
