Official EPSG transformation from CR05 to CR-SIRGAS epoch 2014.59

The EPSG Geodetic Parameter Dataset defines 1 transformation between CR05 (EPSG:5365) and CR-SIRGAS epoch 2014.59 (EPSG:8907). Its parameters, accuracy and area of use are listed below.

CR05 to CR-SIRGAS epoch 2014.59 (1)

EPSG:9751±0.5 m

Method:: Coordinate Frame rotation (geog2D domain)
Area of use:: Costa Rica
Scope:: Transformation of coordinates at 0.5m level of accuracy.

Parameter	Value	Unit
X-axis translation(tx)	-0.16959	metre
Y-axis translation(ty)	0.35312	metre
Z-axis translation(tz)	0.51846	metre
X-axis rotation(rx)	-0.03385	arc-second
Y-axis rotation(ry)	0.16325	arc-second
Z-axis rotation(rz)	-0.03446	arc-second
Scale difference(ds)	0.03693	parts per million

Derived at 16 stations. Transformation is valid at epoch 2014.59 but accuracy will deteriorate due to tectonic deformation. Note that the rotation convention (coordinate frame) differs from that used in the transformation from CR-SIRGAS epoch 2019.24 to CR-SIRGAS epoch 2014.59 (code 11044). May be taken as an approximate transformation to ITRF08 / IGb08 / WGS 84 - see code 9752.

Frequently asked questions

How accurate is converting CR05 to CR-SIRGAS epoch 2014.59?: The most accurate official EPSG transformation between these systems is accurate to about ±0.5 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.
