Ed’s Map Collection:
Ordnance Survey 1:25 000 ‘Explorer’ Greenwich Meridian editions
Page last updated: 27 April 2011
Ordnance Survey’s Explorer maps were awarded the ‘Millennium Products’ accolade by the Design Council in April 1998. During 1999, as part of the run-up to the Millennium celebrations, Ordnance Survey published seventeen of their 1:25 000 ‘Explorer’ series maps with the Greenwich Meridian (0° Longitude) marked boldly in green. This was - at its most basic level - a clever marketing ploy but its aim, according to the official press release, was to enable people along the route of the meridian to plan their millennium parties. The maps are indentified on their covers by a green flash containing the text “Showing the Greenwich Meridian”.

Most of the seventeen sheets only showed the green line for one edition, the exceptions being three in the London area which carried it over to their next revisions in 2001.

The aim of this collection theme is to acquire a copy of each edition of the ‘Explorer’ maps printed with the Greenwich Meridian in green.
