This is indeed an exception. For Lambert_Conformal_Conic_2SP, the order of standard parallel is indifferent (and EPSG and ESRI don't use the same order. Same with MapInfo as far as I remember). This results in the same mathematical projection. So I've added an exception in IsSame() to accept that difference. -- Spatialys - Geospatial professional services http://www.spatialys.com
