(null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Parameters from Corrego Alegre 1961 to SIRGAS 2000 (1) (tfm code 5525) assuming that SIRGAS 2000 and WGS 84 are equal within the accuracy of the transformation.
Brazil - onshore - between 18°S and 27°30'S, also east of 54°W between 15°S and 18°S.
