Frequently Asked Questions
How do I convert Tokyo to JGD2000 coordinates?
Use the coordinate transformation tool above to convert Tokyo (EPSG:4301) to JGD2000 (EPSG:4612). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 9m accuracy.
How do I transform Tokyo to JGD2000 using Proj4js?
Use proj4.defs to define both EPSG:4301 and EPSG:4612, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Tokyo to JGD2000 transformation?
This transformation (EPSG:15483) has an accuracy of 9m using the Geocentric translations (geog2D domain) method. Area of use: Japan - onshore.
