Black Diamond - Ordnance Survey Ireland

Black Diamond is entirely about climbing and skiing. What began with a backyard anvil and a hammer has grown into a global company with offices on three continents that's not just for rock climbers, but one that stands for the spirit of the sports we live. Since 1957, Black Diamond's innovative gear designs have set the standards in numerous areas.
Ordnance Survey Ireland (OSI) has evolved from the Ordnance Survey Office which was established in 1824. OSI maintains the national mapping records for the Republic of Ireland. These maps are designed for tourists and leisure activities. Each one covers an area 40km x 30km at the scale of 1:50000.
