Geodetic CRS: CR05
Datum: Costa Rica 2005
Ellipsoid: WGS 84
Prime meridian: Greenwich
Data source: EPSG
Information source: Instituto Geografico Nacional (IGN).
Revision date: 2025-10-02
Scope: Transformation of coordinates at 0.5m level of accuracy.
Remarks: 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.
Method: Coordinate Frame rotation (geog2D domain)
Area of use: Costa Rica - onshore and offshore.
