Online coordinate converter from NAD83(CORS96) (EPSG:6781) to NAD83(CSRS)v3 (EPSG:8238). Enter your source coordinates and get the result instantly. All transformations happen in your browser — no data is sent to any server.
The EPSG dataset defines official transformation parameters for the reverse direction. See NAD83(CSRS)v3 to NAD83(CORS96) — the parameters are invertible.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:6781", "EPSG:8238", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
