| Z-axis translation(tz) | -38.22 | metre |
Parameter values from SAD69 to SIRGAS 2000 (1) (tfm code 15485) assuming that SAD69 and SAD69(96) are equal within the accuracy of the transformation. Used by Petrobras and ANP throughout Brazil from 1994.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:5527", "EPSG:4674", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
