Convert coordinates from NAD83(HARN) (EPSG:4152) to NAD83(NSRS2007) (EPSG:4759) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 2 transformations between NAD83(HARN) (EPSG:4152) and NAD83(NSRS2007) (EPSG:4759). Each applies to a specific area — pick the one whose area of use covers your data.
Grid files: nadcon5.nad83_1992.nad83_2007.alaska.lat.trn.20160901.bnadcon5.nad83_1992.nad83_2007.alaska.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°.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | 0 | metre |
| Y-axis translation(ty) | 0 | metre |
| Z-axis translation(tz) | 0 | metre |
Accuracy 0.1 to 0.2m in California, 0.05-0.11 in Oregon, elsewhere better than 0.05m.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4152", "EPSG:4759", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
