 The increasing importance of GPS system and the necessity of geographic coordinates to be more and more precise has result in changing the geodesic system ([[glossaire:datum|datum]]) in France on January the 1st 2001. Thus, the French geodesic system 1993 or RGF93 or Lambert 93 has succeeded to the French new triangulation (in French NTF).
 Some features:
-  * Reference of the ellipsoid = IAG GRS 1980
+  * Reference of the [[english:glossary:ellipsoid|ellipsoid]] = IAG GRS 1980
-  * Original Meridien = international Meriden so the Greenwich’s Meridien
+  * Original [[english:glossary:meridian|meridian]] = international Meriden so the Greenwich’s Meridien
   * Deformation compared to Mondial system:
   - Horizontal between 1 and 2 cm
   - Vertical between 2 and 5 cm
 What’s more this geodesic system is compatible with the European one (ETRS89).
-To win in topometric precision the topographers prefer to work in Lambert 93 conic conform in nine areas.
