The data is recorded at 1 Hz along survey lines orientated 165 degrees and line spacing of 200m. Data is gridded using a minimum curvature algorithm. Data is diurnally and IGRF corrected and control line levelled. Different datasets grids were stitched together using the Geosoft suture method and then re-sampled to a master database. Data is recorded in Irish Transverse Mercator (ITM) and latitude and longitude. The latest merged total count data has been collected on a seasonal basis and quality controlled before being merged.
