Coordinate Reference Systems
Transform Coordinates
Remarks
Derived at 2 stations connected to the Adindan (Blue Nile 1958) network through the 1968-69 12th parallel traverse. Accuracy 25m in each axis. Note: The Adindan (Blue Nile 1958) CRS is used in Ethiopia and Sudan, not Senegal.
Frequently Asked Questions
How do I convert Adindan to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Adindan (EPSG:4201) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 44m accuracy.
How do I transform Adindan to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4201 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Adindan to WGS 84 transformation?
This transformation (EPSG:1105) has an accuracy of 44m using the Geocentric translations (geog2D domain) method. Area of use: Senegal - onshore.
