Hello dear Justin and Andrea,
I have make a WCS GetCoverage request by sending GML.It also has response.But how can I extract the data or the TIFF in the xmlhttp.responseXML and display it? I have written some code like that:

“document.all.img.src=xmlhttp.responseXML;”

But it has no result.Thank you very much!
Sincerely yours,
Yang

Long story short, you can't. We do support WCS 1.0, which returns a TIFF
directly, but most browsers are unable to display a TIFF, they should
offer you to store it on the disk or open with an external program instead.

If you need to display a coverage, use WMS, not WCS. WCS is there to perform raw data extraction, not display.

Cheers
