I am using ArcGIS 10.2.

Does anybody know where I can obtain a shapefile or similar for the Irish National Grid? I need a 1 km vector grid with the associated grid references given within an attribute field.

  • 1. You want a shapefile of 1km square polygons? 2. Do you know the EPSG code for the Irish NG? EPSG:29902? spatialreference.org/ref/epsg/29902 – Spacedman Jul 8 '15 at 15:08
  • Or 29903? Or 2157 (Irish Transverse Mercator)? – Spacedman Jul 8 '15 at 15:18
  • ING has a set of grid square references somewhat like MGRS/USNG in the US. British National Grid has similar. – mkennedy Jul 8 '15 at 16:51
  • It looks like EPSG 29902 is the most recent. I'm surprised how difficult it is to find an Irish grid vector. For example, the OSGB grid is available from github.com/charlesroper/OSGB_Grids. I believe it's also available through Ordnance Survey or Natural England, but Charles' GitHub repository is the most easily accessible source. – bio_carta Jul 9 '15 at 13:36
