Maps: Ordnance Survey of Ireland

Information on Map resources at IT, Sligo

Introduction

The Ordnance Survey of Ireland is Ireland's official mapping agency. It was established in 1824 and became a state body under the Ordnance Survey of Ireland act 2001.  The OSI's mapping activity covers almost two centuries, beginning with the 6" sheets produced in 1837 - 1842.  It produces a popular 1:50000 series of maps for general and tourist purposes and through its GeoHive and Mapgenie services, makes available a wealth of digital mapping information.

The National Mapping Agreement allows educational institutions to access Ordnance Survey of Ireland mapping data not normally made available to the general public.  One of the main features is the use of the premium basemaps which display a high level of detail at a large scale.

Ordnance Survey of Ireland Print Maps in the Yeats Library

Print maps in the Yeats Library are held in a series of upright cabinets and plan drawer cabinets in the Infozone.

Most maps are listed and may be searched by keyword or other headings in the Library Print Catalogue.  There are also lists and other information regarding the maps on the cabinets themselves. In addition to providing the title of each map, the lists on the upright cabinets indicate towns and other locations found on each map as a general guide to finding the location you require.

A summary of the Ordnance Survey maps in the cabinets is provided in the tabs Upright Cabinet 1 and Upright Cabinet 2
