<p class="MsoNormal">I am trying to use gdallocationinfo to query point locations from a WCS server and not having any luck. I don't see anything in the docs that says this is unsupported but I can't make it work.<o:p></o:p></p>

<p class="MsoNormal">Anyway, looking at the debug output it appears that the program is querying for a GeoTIFF of a VERY large area and that's failing.<o:p></o:p></p>

<p class="MsoNormal">I actually want to do this with my own WCS server but thought it might be mis-configured somehow so I tried the USGS server. With my own server, gdallocationinfo seems to be requesting a strange shape from the server (as I can see through
the debug output).<o:p></o:p></p>
