New official Guernsey map shows the entire Bailiwick
An official map of Guernsey has been produced, showing the whole Bailiwick.
The States of Guernsey worked with digital mapping company Digimap to produce the new publication.
The fold-out map shows Guernsey on one side and Alderney, Sark and Herm on the reverse. It is the first map since 1979 to use the Ordnance Survey symbols.
The scale is 1:15,000, which equates to 4.25in to one mile. This means the map is almost twice the size of the previous official States maps.
Colin Le Conte, the managing director of Digimap, said: "We were very keen to produce an official map and also one for the guides, scouts and Duke of Edinburgh award people.
"They all need to do their map-reading courses based on Ordnance Survey symbology. So we spoke to Ordnance Survey and they let us use all their symbols on the new map."
Mr Le Conte also explained the decision to include the smaller Bailiwick islands on the new map.
"We felt that if we didn't at this stage, then probably there would never be a new OS type map of those islands," he said.
The first Ordnance Survey map of Guernsey was produced in 1898. There were subsequent revisions in 1939 and 1979.
The States of Guernsey's mapping service, led by David Wakeford, updates its digital mapping information every week and it is hoped a new map will be published every two years.
Mr Wakeford said: "All the surveying now is done on the ground, so the maps will get better and better."
The process is considerably faster today than when the first comprehensive maps of Guernsey were produced.
William Gardner was required to etch every detail on to two copper plates, when he was commissioned to make a map for the Duke of Richmond in 1787.
As with the earlier Legge Survey of 1680, the primary motivation for the work was to provide accurate information about the island's military defences.
Despite this practical purpose however, the artistic flourish of the cartographers is often plain to see. The Legge Survey included several watercolour paintings of harbours and defences.
These pictures are now considered to have considerable historical value.
Mr Le Conte paid tribute to the work of map makers over the centuries.
"Most cartographers are artists and they're trying to tell you a story," he said.
