Transform Coordinates
Remarks
Parameter values from Astro DOS 71 to SHGD2015 (1) (tfm code 7893). Assumes SHGD2015 and WGS 84 can be considered the same to within the accuracy of the transformation.
Frequently Asked Questions
How do I convert Astro DOS 71 to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Astro DOS 71 (EPSG:4710) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 1m accuracy.
How do I transform Astro DOS 71 to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4710 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Astro DOS 71 to WGS 84 transformation?
This transformation (EPSG:7894) has an accuracy of 1m using the Geocentric translations (geog2D domain) method. Area of use: St Helena - St Helena Island.
