1923 MOT Map Sheet 33.jpg

This SABRE Maps Coverage Project is to provide online coverage of the OS Ministry of Transport Road Map series.

These maps are probably the single most important historical mapping series from the early days of road numbering within Great Britain, with the initial coverage being to show the brand-new road numbers across the whole of Great Britain. They were then updated during the 1920s to keep pace with the early changes in the network at a time when no other Ordnance Survey mapping carried road numbers.

The importance of the series declined in the 1930s when the OS Ten Mile Road Map of Great Britain became the official series of record, and road numbers started to appear on OS Quarter Inch and OS One Inch Fifth Edition sheets. There was a final hurrah following the 1935 changes when a number of maps were reissued.

Bear in mind that the older OS Half Inch series confusingly comes in covers called Ordnance Survey Road Map, and some sheets were revised into the late 1920s and early 1930s, but these are based on the ordinary pre-World War 1 series with no road numbers printed on them, and are not the same thing as the Ministry of Transport Road Maps. As such, these maps are not part of this Coverage Project.

Which projection type are these maps?

MoT maps of England and Wales use the Cassini (Delamere) projection and should be georeferenced accordingly; whilst those of Scotland use the Bonne (Scotland) projection.

Technical info

MOT maps predate the National Grid, and are derived off base maps that predate the Popular Edition which unified the whole of the UK under one projection system.

England and Wales

The English and Welsh maps use the Cassini (Delamere) projection. This is defined from an origin in Delamere Forest, Cheshire (roughly where the A54 meets the A556) - approximately here.

Each map is broken up into 4x4 mile (ie: 21,120x21,120 feet) grid squares.

For English and Welsh maps, there are usually 13 1/2 west to east ("1" to "14" with 14 being half length, and 9 or 12 north to south ("A" to "J" or "M", "I" is not used). Most maps are "J" maps - the "M" maps include sheets 35 and 40. Sheet 40 is also narrower than most, with only 11 1/2 squares. The actual Delamere Forest origin is approximately 11/64 miles (907ft 6in) north and 9/128 miles (371ft 3in) west of the nearest grid square corner on sheet 12 (which is treated as the "false" origin for all other maps).

Most maps align exactly with each other, with only a few overlaps, the size of which is always a whole number of miles. The edges of the grid squares therefore generally line up with each other. The notable exceptions appear to be sheets 21, 31, 35 and 36, which have been aligned to fit as much land on the map without requiring an insert.

Scotland

The Scottish maps use the Bonne (Scotland) projection, defined in feet from latitude 57.5, longitude -4, which happens to be about halfway between Inverness and Nairn here. This is (from measuring map scans) about 1042 feet east and 438 feet north of the nearest grid square.

Scottish maps appear to be all 12 squares by 9 squares, though the orientation can vary between portrait (9 across, 12 down) and landscape (12 across, 9 down). A couple of maps (eg: sheet 24) overlap substantially with others.

General

All maps also has markers and bars along the edges specifying a specific arc of longitude or latitude, at minute intervals (with 60 minutes to a degree), with every 5 minutes marked explicitly. Latitude is always positive, longitude is positive east of the Greenwich Meridian, or negative west of it. This is useful for testing the corner of the map is where you think it should be.
