ISN93 to ISN2016 (1)

EPSG:9232±0.05 m
Method:
NTv2
Area of use:
Iceland
Scope:
Spatial referencing.

Grid file: ISN93_ISN2016.gsb

Grid transformation based on Kriging between ISN93 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.

Frequently asked questions

How accurate is converting ISN93 to ISN2016?
The most accurate official EPSG transformation between these systems is accurate to about ±0.05 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
