This is the landing page to the Society resource of map Indexes. Under this section, we have three pages detailing:

  • Standard series indexes

    These diagrams are designed to be printed on A4 paper and may be copied freely for use in map libraries, or for private study or research. They have been prepared by Chris Higley, based on the work of the late Brian Adams, David Archer, Roger Hellyer, the late Tim Nicholson, Richard Oliver and others.

  • Rare indexes

    This section is for images of index diagrams that are unusual in themselves.

  • A KML file

    This is for download for use in Google Earth. This has the definitions of the sheet boundaries for all Ordnance Survey One-Inch and 1:50,000 map Series of Great Britain and Ireland and 1:25,000 Provisional Series of UK.
