Official EPSG transformations from NAD83(HARN) to NAD83(FBN)

The EPSG Geodetic Parameter Dataset defines 3 transformations between NAD83(HARN) (EPSG:4152) and NAD83(FBN) (EPSG:8860). Each applies to a specific area — pick the one whose area of use covers your data.

NAD83(HARN) to NAD83(FBN) (1)

EPSG:8861±0.05 mBest accuracy
Method:
NADCON5 (3D)

Frequently asked questions

How accurate is converting NAD83(HARN) to NAD83(FBN)?
The most accurate official EPSG transformation between these systems is accurate to about ±0.05 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) 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.
