NAD83(HARN) to WGS 84 (2)

EPSG:1900±1 mBest accuracy

Method:: Coordinate Frame rotation (geog2D domain)
Area of use:: USA - CONUS - onshore
Scope:: Approximation for medium and low accuracy applications ignoring static/dynamic CRS differences.

Parameter	Value	Unit
X-axis translation(tx)	-0.9738	metre
Y-axis translation(ty)	1.9453	metre
Z-axis translation(tz)	0.5486	metre
X-axis rotation(rx)	-1.3357e-7	radian
Y-axis rotation(ry)	-4.872e-8	radian
Z-axis rotation(rz)	-5.507e-8	radian
Scale difference(ds)	0	parts per million

Approximation derived ignoring time-dependent parameters and assuming ITRF94(1996.0) and WGS 84, plus NAD83(CORS94) and NAD83(HARN), can be considered the same within the accuracy of the transformation. Replaced by NAD83(HARN) to WGS 84 (3) (code 1901).

NAD83(HARN) to WGS 84 (3)

EPSG:1901±1 m

Method:: Coordinate Frame rotation (geog2D domain)
Area of use:: USA - CONUS - onshore
Scope:: Approximation for medium and low accuracy applications ignoring static/dynamic CRS differences.

Parameter	Value	Unit
X-axis translation(tx)	-0.991	metre
Y-axis translation(ty)	1.9072	metre
Z-axis translation(tz)	0.5129	metre
X-axis rotation(rx)	-1.25033e-7	radian
Y-axis rotation(ry)	-4.6785e-8	radian
Z-axis rotation(rz)	-5.6529e-8	radian
Scale difference(ds)	0	parts per million

Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84, plus NAD83(CORS96) and NAD83(HARN), can be considered the same within the accuracy of the tfm. In USA only replaces tfm code 1900.

NAD83(HARN) to WGS 84 (1)

EPSG:1580±2 m

Method:: Geocentric translations (geog2D domain)
Area of use:: USA - HARN
Scope:: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Parameter	Value	Unit
X-axis translation(tx)	0	metre
Y-axis translation(ty)	0	metre
Z-axis translation(tz)	0	metre

For many purposes NAD83(HARN) can be considered to be coincident with WGS 84.

Frequently asked questions

How accurate is converting NAD83(HARN) to WGS 84?: The most accurate official EPSG transformation between these systems is accurate to about ±1 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.
