[gdal-dev] WCS_GDAL Driver Image SubSet Request

[jratike80]

Hi,

Do you want to make is somehow impossible to request data beyound the
BoundingBox that you defined in the XML file? If you just want to get data
from the rectangle that you or your users define, gdal_translate with the
regular -spat option should work out-of-the-box.
