Transform Coordinates

Remarks

Derived at 19 stations, RMS = 6cm. Note: Because of the large rotations about the Y- and Z-axes this transformation is not reversible. For the reverse transformation use SHGD2015 to Astro DOS 71 (2) (code 9226).

Frequently Asked Questions

How do I convert Astro DOS 71 to SHGD2015 coordinates?

Use the coordinate transformation tool above to convert Astro DOS 71 (EPSG:4710) to SHGD2015 (EPSG:7886). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geog2D domain) method with 0.1m accuracy.

How do I transform Astro DOS 71 to SHGD2015 using Proj4js?

Use proj4.defs to define both EPSG:4710 and EPSG:7886, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the Astro DOS 71 to SHGD2015 transformation?

This transformation (EPSG:7895) has an accuracy of 0.1m using the Position Vector transformation (geog2D domain) method. Area of use: St Helena - St Helena Island.
