Official EPSG transformations from SAD69(96) to WGS 84

The EPSG Geodetic Parameter Dataset defines 2 transformations between SAD69(96) (EPSG:5527) and WGS 84 (EPSG:4326). Each applies to a specific area — pick the one whose area of use covers your data.

SAD69(96) to WGS 84 (1)

EPSG:5543±1 mBest accuracy
Method:
NTv2
Area of use:
Brazil - onshore south of 14°S and east of 53°W
Scope:
(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.

Grid file: SAD96_003.gsb

Parameters values taken from SAD69(96) to SIRGAS 2000 (1) (tfm code 5529) assuming that SIRGAS 2000 and WGS 84 are equal within the accuracy of the transformation.

SAD69(96) to WGS 84 (2)

EPSG:6195±5 m
Method:
Geocentric translations (geog2D domain)
Area of use:
Brazil
Scope:
(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.
ParameterValueUnit
X-axis translation(tx)-67.35metre
Y-axis translation(ty)3.88metre
Z-axis translation(tz)-38.22metre

Parameter values from SAD69(96) to SIRGAS 2000 (2)) (tfm code 5881) assuming that SIRGAS 2000 and WGS 84 are equal within the accuracy of the transformation, based on SAD69 to SIRGAS 2000 (1)) (tfm code 15485). Used by Petrobras and ANP from 1994.

Frequently asked questions

How accurate is converting SAD69(96) to WGS 84?
The most accurate official EPSG transformation between these systems is accurate to about ±1 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
