The data shows polygonal and selected linear geological information, sourced from GSNI 1:10 000 or 1:10 560 scale maps of Northern Ireland. However, geological units are identified using the most up-to-date nomenclature and that may differ from that on the printed maps. The geology was fitted to the relevant Ordnance Survey of Northern Ireland topographic base at the time of survey. The dataset is currently under expansion and point data will be added progressively in future releases. The data is available in vector format. GSNI licensing terms and conditions apply to external use of the data.
The data consists of 6 themes;
