OSi Discovery is the name of a series of 1:50,000 maps published by Ordnance Survey Ireland. It is the counterpart in the Republic of Ireland of Ordnance Survey of Northern Ireland's OSNI Discoverer series. The maps are designed with tourist and leisure activities in mind, and each sheet (of which there are 71) covers an area of 40 by 30 km. There have been four editions so far in the series.
The map covers are predominately blue (more expensive weatherproof versions, however, are orange) and feature a photograph taken in the map's area of coverage, a zoom-in of part of the map itself, and, on the back cover, an all-Ireland map indexing all the maps in the OSi Discovery and OSNI Discoverer ranges.
