Professional Risk Notice

Using the wrong datum or applying coordinates without grid-to-ground correction can cause 1-400 metre positional errors —a leading cause of surveying negligence claims and contract disputes.

Geodetic Shift Tolerances

While DGN95 is often assumed within ±1m of WGS84, high-precision engineering requires chaining through SRGI2013 using a 7-parameter shift to achieve ~0.2m mean residual accuracy.

Civil & Legal Implications

Badan Informasi Geospasial (BIG) explicitly treats older datums as obsolete. Misusing the 'DGN95≁EGS84' assumption on offshore concessions can produce positioning errors larger than contractual tolerances.

Real-World Infrastructure Risk

Offshore LNG terminals and deep-water pipelines in Indonesia require sub-meter alignment. Relying on a 0-parameter shift can skew underwater asset positioning by over a meter.

Authority よくあるご質問 (FAQ)

Are DGN95 and WGS84 exactly the same?

No. While they are very close natively, tectonic plate movement and datum realization differences mean they diverge by up to 1 meter. Authoritative Indonesian mapping requires transformation to SRGI2013 for legal validity.
