<p>Hi list,</p>
<p>I am setting up a WMS server using Mapserver 7.6.2 and want
to return a html response to a GetFeatureInfo request where
the response contains the coordinates of the GFI click. The
WMS supports multiple coordinate systems, so ideally I'd like
to have the coordinates in a CRS that I can predetermine.</p>
<p>I have a test template file as follows:</p>
<pre><!-- MapServer Template -->
<p>
Map X/Y : [mapx],[mapy]<br>
Map LL : [maplon],[maplat]
</p></pre>
<p>If I configure an 'old style' TEMPLATE in the map file,
directly referencing the html template as follows:</p>
<pre>LAYER
TEMPLATE "coord_comp.html"</pre>
<p>With a GFI request specifying a CRS of EPSG:27700:</p>
<pre>...&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo
&BBOX=379766.9556955648586154,58602.32640402266406454,405538.15569556411355734,94300.79913129436317831
&CRS=EPSG:27700&WIDTH=649&HEIGHT=899&LAYERS=test&STYLES=&FORMAT=image/jpeg&QUERY_LAYERS=test
&INFO_FORMAT=text/html&I=268&J=647&FEATURE_COUNT=50
</pre>
<p>the output of is as follows:<br>
</p>
<p>Map X/Y : 390428.846605,68589.162768<br>
Map LL : 50.516415,-2.135015</p>
<p>When a similar requests are made specifying a CRS of
EPSG:4326:</p>
<pre>...&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo
&BBOX=50.33460688675980776,-2.28814701603231718,50.84060858090575863,-1.92285769511938809
&CRS=EPSG:4326&WIDTH=649&HEIGHT=899&LAYERS=test&STYLES=&FORMAT=image/jpeg&QUERY_LAYERS=test
&INFO_FORMAT=text/html&I=298&J=579&FEATURE_COUNT=50
</pre>
<p>the output is as follows:</p>
<p>Map X/Y : 50.514437,-2.120136<br>
Map LL : [maplon],[maplat]</p>
<p>The maplat and maplon templates are not substituted.</p>
<p>Mapserver has been compiled with PROJ support and a
PROJECTION has been defined for the layer in the map file.</p>
<p>The CRS of the source data is EPSG:27700</p>
<p>I was hoping that the maplat and maplon templates would
provide me with a consistent source of coordinate information,
independent of the request CRS. Can anybody shed any light on
the observed behaviour?
<br>
</p>
Thanks,<br>
<p>Andy<br>
