[mapserver-users] WCS resX, resY

[turtlewax]

I'm trying to get a handle on the relationship between the "wcs_resolution"
in the map file, and the resX, resY parameters in the request. Looking at
the description in the OGC spec:
=================================
RESX=x RESY=y : Request a coverage subset with a specific spatial resolution
along each axis of the reply CRS. The values are given in the units
appropriate to each axis of the CRS.
=================================

QUESTION 1:  If CRS = EPSG:4326, would the unit be ??? 
["degree",0.0174532925199433] ???

QUESTION 2: As a consumer of WCS, I'm looking for a way to ask for
"Full-Res", "1/2 res", etc.  But if I understand the "resX,resY" definition,
it seems like the consumer needs in-depth knowledge of the underlying
source, and needs to perform calculations to determine the desired resX/resY
values.  

This leads me to believe that my understanding of these parameters is
incorrect. Looking for clarification.

Thanks in advance.
