NAD83(CSRS)v7 to NAD83(CSRS)v8 (1)

EPSG:10514±0.01 m

Method:: Position Vector transformation (geocentric domain)
Area of use:: Canada
Scope:: Geodesy.

Parameter	Value	Unit
X-axis translation(tx)	0	metre
Y-axis translation(ty)	0	metre
Z-axis translation(tz)	0	metre
X-axis rotation(rx)	0	milliarc-second
Y-axis rotation(ry)	0	milliarc-second
Z-axis rotation(rz)	0	milliarc-second
Scale difference(ds)	0	parts per billion

Scale difference in ppb where 1/billion = 1E-9 or nm/m. NAD83(CSRS)7 and NAD83(CSRS)v8 are referenced to the same coordinate reference epoch (2010.00) and considered compatible with each other at the millimetre level.

Frequently asked questions

How accurate is converting NAD83(CSRS)v7 to NAD83(CSRS)v8?: The most accurate official EPSG transformation between these systems is accurate to about ±0.01 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.
