NTv2 grid derived by ESRI from that supplied by GSI in application patchjgd.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | 0 | metre |
| Y-axis translation(ty) | 0 | metre |
| Z-axis translation(tz) | 0 | metre |
Excludes areas of northern Honshu affected by 2008 Iwate-Miyagi and 2011 Tohoku earthquakes. For these areas use GSI PatchJGD application or JGD2000 to JGD2011 (1) (tfm code 6713).
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4612", "EPSG:6668", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
