John, Jukka, I confirm that a check for the MAXSIZE directive was introduced for WCS in version 6.0 (see #3204). At the moment there's no possibility to set the values independently for WMS and WCS. I started to think about a more clever method of limiting WCS responses based on the result volume. E.g. a RGB image of same pixel size is way smaller than a multiple bands float32 coverage. What are your requirements for such a limiting mechanism?
Btw. you might be interested in version 2.0 of the WCS standard which is also supported by MapServer. cu Stephan On Fri, 2011-10-21 at 20:04 +0000, Rahkonen Jukka wrote: > For our server the practical limit is somewhere around 5000x5000 pixels which > makes 75 MB per image.
