Description (last modified by Even Rouault)

When doing SetWellKnownGeogCS() with WGS84, WGS72, NAD27 and NAD83, the result is not strictly equal to the corresponding ImportFromEPSG()

Differences are :

  • TOWGS84 node for WGS84
  • AUTHORITY 9108 instead of 9122 for degree
  • inverse flattening of NAD27 is 294.978698213898 instead of 294.9786982138982
