Frank,
listgeo from FWTools 2.0.6 produces [1] for a GeoTIFF in LAEA
(EPSG:3035) projection. However when using listgeo from
libgeotiff-1.3.0, then there seem to be some problems: "Datum:
6258/(unknown), Ellipsoid: 0/(unknown)", see [2].
Is this a bug in libgeotiff-1.3.0, which should have better "support for
LAEA, as contributed by EvenR.", or is it related to libgeotiff's EPSG
7.1 upgrade, or am I doing something wrong, by the end of the day (it is
22:00H over here in Europe ;-) .
