FAQ

What is EPSG:28992?

EPSG:28992 (Amersfoort / RD New) is a projected coordinate reference system on the Amersfoort datum using the Oblique Stereographic method, with coordinates in metres. Area of use: Netherlands - onshore, including Waddenzee, Dutch Wadden Islands and 12-mile offshore coastal zone.

Where can EPSG:28992 be used?

Its area of use is: Netherlands - onshore, including Waddenzee, Dutch Wadden Islands and 12-mile offshore coastal zone.

Is EPSG:28992 in metres or degrees?

EPSG:28992 is projected, so coordinates are easting and northing in metres, not degrees.

How do I convert EPSG:28992 to latitude and longitude?

Transform from EPSG:28992 to EPSG:4326 (WGS 84). In GeoCAD Bridge open the coordinate converter with EPSG:28992 preselected, enter easting and northing, and choose WGS 84 as the target.

How accurate is the transformation from EPSG:28992 to WGS 84?

The most accurate EPSG transformation listed here is “axis order change (2D) + Amersfoort to WGS 84 (4) + axis order change (2D)”, with a stated accuracy of 1 m for Netherlands - onshore, including Waddenzee, Dutch Wadden Islands and 12-mile offshore coastal zone.. Always check the area of use before applying it.
