Name: Chua to WGS 84 (1)
Method: Geocentric translations (geog2D domain)
Remarks: Derived at 6 stations. Accuracy 6m, 9m and 5m in X, Y and Z axes.
Information source: U.S. Defense Mapping Agency TR8350.2 September 1987.
Revision date: 2020-03-14
Unit: degree (supplier to define representation)
Geodetic CRS: Chua
Datum: Chua
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Revision date: 2009-06-02
Scope: Geodesy.
Remarks: The Chua origin and associated network is in Brazil with a connecting traverse through northern Paraguay. In Brazil used only as input into the Corrego Allegre adjustment (CRS code 4225), except for government work including SICAD in Distrito Federal.
Area of use: Brazil - south of 18°S and west of 54°W, plus Distrito Federal. Paraguay - north.
Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
