Discoverer map series for Northern Ireland
 Mapmart Price :   £6.00 

1:50 000 scale maps, (1.25 inches to 1 mile) The series is numbered on an all-Ireland basis and Ordnance Survey of Northern Ireland is responsible for the design and publication of the sheets that cover Northern Ireland and adjoining parts of the Republic of Ireland. The layout incorporates a number of overlaps.The map is derived from the latest large scale material, supplemented by new aerial photographs and ground surveys. It is the country's most detailed small-scale map and as well as showing all the features that were on the One-Inch map, the slightly larger scale allows for the inclusion of additional features and names and gives an increase in clarity which is more evident in built-up areas. In high moorland areas where detail is scarce, prominent fences and walls are shown. This series is fully metricated in full colour and carries the Irish Grid at 10 Kilometre intervals. It also shows relief by contours at 10 metre vertical intervals with layered tints. Height information is expressed in metres above Mean Sea Level at Malin Head, County Donegal.
