Fifth Edition cover

This SABRE Maps Coverage Project is to provide online coverage of the OS One Inch Fifth Edition and associated maps; such as Tourist or District sheets at the One Inch scale in Fifth Edition style; and the Two-Inch Scilly Isles maps. Because only maps covering the southern parts of England were published (with the exception of two Scottish Tourist sheets), it's not possible to offer coverage of the whole of Great Britain.

Generally speaking, Fifth Edition maps come in several types:

  • Relief, showing hill shading
  • Contour, showing hills by the use of contour lines
  • Black
  • Outline

Some map revisions were printed as one, two, or all types, and in these cases SABRE Maps uses one of the Relief or Contour versions, and never an Outline or Black version.

The eventual aim is to get a copy of every revision of every Fifth Edition sheet online, within the above caveats.

Which projection type are these maps?

The OS One Inch Fifth Edition uses the National Yard Grid and should be georeferenced accordingly.

How do I find out the date of each map?

Early Fifth Edition maps have revision codes that look like this, 9200/31 in this example, which dates the map to 1931
Later Fifth Edition revision code, 3035 in this example, dating the map to 1935
See Also: SABRE Maps/OS Copyright

Annoyingly, the OS didn't actually put the exact date of the map on each map. The date that appears on the map (usually with the words First published by the Director General at the Ordnance Survey Office) often is not the correct date of the map, but the date of the first revision of the map. Roads, along with other minor corrections were actually updated on every revision, so the map you have may be from a number of years away from the most obvious date. Fortunately, Fifth Edition maps have some of the most easily understood revision codes on them, so one look at them will tell you which map revision you have.

Revision codes on Fifth Edition sheets can be found in one of two places. In early Fifth Edition maps, they are located right at the bottom right of the map sheet, underneath the margin texts; whilst in most sheets, they are located immediately under the bottom left corner of the maps themselves, between the map and the key.

Revision codes appear in the heading within SABRE Maps, and so this information is extremely valuable to capture.

Progress by every sheet ever printed

This table only gives "Relief" and "Colour" editions, which are the most useful. There were also other versions of Fifth Edition mapping, such as "Black" and "Outline", which are not included here.

Circa 1934, during the general migration from "Relief" (with coloured heights) to "Colour" (with contour lines), there were often printings of both types in the year, and sometimes two of one type. These are almost identical in other respects and so the form "x/34" or "x34" is used for the various printings as only one is required for online mapping. The exact edition used requires capturing for the map annotation display.
