I finally realized that I need to request a geotiff from WCS to do
anything spatial with the image, because the response doesn't
necessarily contain all the pixels for the request BBOX, like WMS.
I'm getting an error trying to read the geotiff us this code though:
GeoTiffReader reader = new GeoTiffReader (inputStream);
GridCoverage2D gridCoverage2D = reader.read(null) ;

I've read through the other questions reporting this error, and I've
confirmed that the JAI jars are only on the path via the pom, but it
still seems like it must be a classpath issue.
I'm using:
<artifactId>gt-geotiff</artifactId>
<version>2.7.0.2</version>
Is there anything else I can check?

It's 4 band, but the 4th is IR. It ended up just being this:

Searched around a bit but could not find freely downloadable data with
RGB-IR structure (lots of pages
referring to the data type, no actually working download links).
Do you have a sample?
Maybe that's what's described in the spec, but it wasn't clear to
me. Getting the image back from the .eml is a little fiddly too.
Yeah, unfortunately OGC thought that was a good idea. Use store=true
in your request, the server will give you
back a xml document with a link where you can download the file directly
Cheers
