[gdal-dev] ArcSDE raster cell size issue

[bartvde at osgis.nl]

Hi list,

I am trying to access an ArcSDE raster through GDAL, and gdalinfo gives me
the following info:

gdalinfo
SDE:geodatabase.ad.rws.nl,port:5151,5151,RWS_LEZEN,XXXX,HOOGTE.AHN2_5
Driver: SDE/ESRI ArcSDE
Files: none associated
Size is 41151, 48412
Coordinate System is:
PROJCS["RD_New",
    GEOGCS["GCS_Amersfoort",
        DATUM["Amersfoort",
            SPHEROID["Bessel_1841",6377397.155,299.1528128]],
        PRIMEM["Greenwich",0.0],
        UNIT["Degree",0.0174532925199433]],
    PROJECTION["Double_Stereographic"],
    PARAMETER["False_Easting",155000.0],
    PARAMETER["False_Northing",463000.0],

Whereas ArcCatalog says the grid is 5 by 5 meters, which is the expected
cell size. Does anybody have an idea why GDAL is reporting a different
cell size?
