SIRGAS 2000 / Brazil Polyconic

Latin America , accuracy 0.02 m, code 9980 (default) [grid]

Selected transformation

Method: NTv2

Grid Files: SIRGAS2000-to-SIRGAS-CONSIR17P01.gsb

Remarks: Derived at 79 stations at epoch 2015.00. Accuracy deteriorates with time due to intra-plate seismic deformation.
