Frequently asked questions

How accurate is converting AGD66 to PNG94?: The most accurate official EPSG transformation between these systems is accurate to about ±0.5 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation 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.
