#5511 closed defect (fixed)

Issue when importing proj.4 string with omerc +no_uoff and +alpha != 0 but no +gamma

Description

Two issues :

  • proj.4 currently doesn't mark +no_uoff as used so OCTProj4Normalize() loose it
  • when importing parameters for omerc, the default value taken for gamma is 0. Looking at PJ_omerc, it appears that the default value should be the same as alpha
