Transform Coordinates

Remarks

Derived at 6 stations. Accuracy 2m in each axis. Along with CTs 6974 and 6976, replaces SAD69 to WGS 84 (5) (code 1868). Also used as a CT from SAD69 to SIRGAS-Chile - see code 6968. Note: SAD69 adopted by Chile authorities only south of 43°30'S.

Frequently Asked Questions

How do I convert SAD69 to WGS 84 coordinates?

Use the coordinate transformation tool above to convert SAD69 (EPSG:4618) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 4m accuracy.

How do I transform SAD69 to WGS 84 using Proj4js?

Use proj4.defs to define both EPSG:4618 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the SAD69 to WGS 84 transformation?

This transformation (EPSG:6975) has an accuracy of 4m using the Geocentric translations (geog2D domain) method. Area of use: Chile - onshore 32°S to 36°S.
