OSNI Open Data - BenchMarks - Height

OSNI Benchmark data consists of point data giving the location of the points, along with the associated text which shows the height value. Bench marks are shown in metres above mean sea level. This data is not maintained. We recommend using a Global Navigation Satellite System (GNSS) and the latest geoid model to find orthometric height in Northern Ireland.
