[mapserver-users] GetMap vs GetFeatureinfo sort

[Jörg Thomsen (WhereGroup)]

Hi,

hm, I would have expected the classes to be drawn in the same order as
in the mapfile.

You could try to use the label-section with geomtransform 'labelpoint'
[1], perhaps mapserver there takes care of the mapfile order...

Another option would be to use grouped layers, I guess you found this
already:
