Geodetic CRS: SIRGAS 2000
Datum: Sistema de Referencia Geocentrico para las AmericaS 2000
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: SIRGAS Working Group I, "Relación y modelos de transformación entre las soluciones SIRGAS95, SIRGAS2000 y SIR17P01. Resultados obtenidos", presented at SIMPOSIO SIRGAS 2021 Perú, 29 Nov-01 Dec 2021.
Revision date: 2022-04-08
Scope: Transformation of coordinates at 0.02m level of accuracy.
Remarks: Derived at 79 stations at epoch 2015.00. Accuracy deteriorates with time due to intra-plate seismic deformation.
Method: NTv2
Area of use: Latin America - Central America and South America, onshore and offshore.
