ISN2004_ISN2016.gsb
Grid transformation based on Kriging between ISN2004 and ISN2016. Accuracy is better than 5 cm in stable areas but can be around 25 cm in areas that have suffered deformation due to earthquake or volcanic eruption.

Conformal mapping at scales of 1:500,000 and smaller.
At applicable scales (1:500,000 and smaller) may be considered consistent with ETRS89-extended / LCC Europe (CRS code 3034): see CT 9042. Replaced by ISN2016 / LCC Europe (CRS code 9040).
Iceland - onshore and offshore.
Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
