Coordinate Reference Systems
Transform Coordinates
Remarks
Derived at 5 stations. Accuracy 3m, 3m and 8m in X, Y and Z axes. Note: Lesotho does not use Arc 1950 but does use Cape (CRS code 4222); Cape and Arc 1950 datums share a common fundamental point.
Frequently Asked Questions
How do I convert Arc 1950 to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Arc 1950 (EPSG:4209) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 10m accuracy.
How do I transform Arc 1950 to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4209 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Arc 1950 to WGS 84 transformation?
This transformation (EPSG:1116) has an accuracy of 10m using the Geocentric translations (geog2D domain) method. Area of use: Lesotho.
