Transformatsiooniparameetrid Eestis kasutatavate geodeetiliste daatumite jaoks
Transformation parameters for geodetic datums used in Estonia



GRS-80 (EUREF) – WGS-84

Väljavõte keskkonnaministri määrusest „Geodeetilise süsteemi kehtestamine” 5. veebruarist 2004:

(6) Eestis loetakse EUREF-EST97 koordinaadid ja Ülemaailmse Geodeetilise Süsteemi 1984 (WGS84) realisatsiooni WGS84(G873) koordinaadid identseteks.

According to regulation of Minister of Environment from 5. Feb 2004 EUREF-EST97 coordinates are regarded as identical to WGS84 realization G873.
