[mapserver-users] WCS GetCoverage responses in multi-part mime format

[Stephan Meißl]

Bryan,

from my experience firefox does pretty good with multipart files.
Usually the first part is of type "text/xml" which is shown in the
browser directly and the second part is opened in an external image
viewer. Unfortunately I don't know a way how to turn multipart of with
WCS 1.1.

However, I do know that in WCS 2.0 you explicitly have to request
multipart files ("mediatype=multipart/mixed") which means by default
plain image files are returned. Please note that WCS 2.0 is a fairly new
standard which adopts the new modular specification model of OGC and
some of the extensions are not yet published which might cause some
problems for the time being.

Best regards,
Stephan
