Coordinate Reference Systems
Transform Coordinates
Remarks
Derived at 8 stations. Accuracy 2m in each axis. Along with CTs 6975 and 6976, replaces SAD69 to WGS 84 (5) (code 1868). Also used as a CT from SAD69 to SIRGAS-Chile - see code 7448. 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:6974) has an accuracy of 4m using the Geocentric translations (geog2D domain) method. Area of use: Chile - onshore north of 32°S.
