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

Center coordinates
-60.19 -20.64

WGS84 bounds:
-62.57 -22.0
-57.81 -19.29

Paraguay - north of 22°S.
