South Yemen to WGS 84 (1)

EPSG:1682±5 m

Method:: Geocentric translations (geog2D domain)
Area of use:: Yemen - South Yemen - mainland
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.

Parameter	Value	Unit
X-axis translation(tx)	-76	metre
Y-axis translation(ty)	-138	metre
Z-axis translation(tz)	67	metre

Parameter values taken from South Yemen to Yemen NGN96 (1) (code 1539) assuming that NGN96 is equivalent to WGS 84 within the accuracy of the transformation.

Frequently asked questions

How accurate is converting South Yemen to WGS 84?: The most accurate official EPSG transformation between these systems is accurate to about ±5 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation 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.
