Official EPSG transformation from NAD83(FBN) to NAD83(PA11)

The EPSG Geodetic Parameter Dataset defines 1 transformation between NAD83(FBN) (EPSG:8860) and NAD83(PA11) (EPSG:6322). Its parameters, accuracy and area of use are listed below.

NAD83(FBN) to NAD83(PA11) (1)

EPSG:8864±0.05 m
Method:
NADCON5 (3D)
Area of use:
American Samoa - 2 main island groups and Rose Island
Scope:
Geodesy.

Grid files: nadcon5.nad83_2002.nad83_pa11.as.lat.trn.20160901.bnadcon5.nad83_2002.nad83_pa11.as.lon.trn.20160901.b

Uses NADCON5 method which expects longitudes positive east in range 0-360°; EPSG source and target CRSs have longitudes positive east in range -180° to +180°.

Frequently asked questions

How accurate is converting NAD83(FBN) to NAD83(PA11)?
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.
