Mandatory for SICAD use until 2005. Replaced by Chua to SIRGAS 2000 (tfm code 4069).
Frequently Asked Questions
How do I convert Chua to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Chua (EPSG:4224) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 5m accuracy.
How do I transform Chua to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4224 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Chua to WGS 84 transformation?
This transformation (EPSG:3972) has an accuracy of 5m using the Geocentric translations (geog2D domain) method. Area of use: Brazil - Distrito Federal.
