EPSG:9751

CR05 to CR-SIRGAS (1)

Attributes

Geodetic CRS: CR05

Datum: Costa Rica 2005

Ellipsoid: WGS 84

Prime meridian: Greenwich

Data source: EPSG

Information source: Instituto Geografico Nacional (IGN).

Revision date: 2021-08-19

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. 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.

Description: (0,)
