<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>When searching for a suitable wms layer is there some key
phrase or word that tells whether or not you can do anything other than just
view the data. For example if I have a set of points and want to get the
value of the underlying data from the wms layer at each of the points. most
wms layers appear not to allow this, but other than just randomly trying large
numbers of different wms services is there any way of identifying which might
allow access to this underlying data?<o:p></o:p></span></font></p>
