Sistem Referensi Geospasial Indonesia 2013 epoch 2021.0

Attributes

Ellipsoid: WGS 84

Prime meridian: Greenwich

Data source: EPSG

Information source: Geospatial Information Agency (BIG), https://srgi.big.go.id

Revision date: 2025-11-12

Scope: Engineering survey, topographic mapping (large and medium scale).

Remarks: This is a static snapshot at epoch 2021.0 of the SRGI2013 dynamic datum (reference frame) (datum code 1293). Between 2012 and 2020, the coordinate reference frame has experienced a significant shift of between 20 - 70 cm due to the effects of tectonic plate movements.

Area of use: Indonesia - onshore and offshore.
