Remarks

Scale difference in ppb where 1/billion = 1E-9 or nm/m. Source and target CRSs defined from ITRF2000 by common transformations (codes 6866 and 8261). 6866 defines CORS96 from 1st January 2002 to 6th September 2011.

Frequently Asked Questions

How do I convert NAD83(CSRS)v4 to NAD83(CORS96) coordinates?

Use the coordinate transformation tool above to convert NAD83(CSRS)v4 (EPSG:8242) to NAD83(CORS96) (EPSG:6781). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geocentric domain) method with 0m accuracy.

How do I transform NAD83(CSRS)v4 to NAD83(CORS96) using Proj4js?

Use proj4.defs to define both EPSG:8242 and EPSG:6781, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the NAD83(CSRS)v4 to NAD83(CORS96) transformation?

This is an exact transformation (EPSG:9128) with no loss of precision (0m accuracy) using the Position Vector transformation (geocentric domain) method. Area of use: North America - Canada, US (Conus+AK), PRVI.
