<div>Hi,<br>
</div>
<div><br>
</div>
<div>This seems like a bug - there is a check to see if the Map
projection is a geographic coordinate system [1], and if it is
then it skips all the [maplon], [maplat], [minlon] etc.
substitutions. If it is in another projection then the point
and extent are reprojected to latlon and included in the
template. <br>

<p>Hi list,<br>
</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.<br>
</p>
<p>I have a test template file as follows:<br>
</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:<br>
</p>
<pre>LAYER
TEMPLATE "coord_comp.html"
</pre>
<p>With a GFI request specifying a CRS of EPSG:27700:<br>
</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><br>
</p>
<p>the output of is as follows:<br>
</p>
<div>Map X/Y : 390428.846605,68589.162768<br>
</div>
<div>Map LL : 50.516415,-2.135015<br>
</div>
<p>When a similar requests are made specifying a CRS of
EPSG:4326:<br>
</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:<br>
</p>
<p><br>
</p>
<div>Map X/Y : 50.514437,-2.120136<br>
</div>
<div>Map LL : [maplon],[maplat]<br>
</div>
<p>The maplat and maplon templates are not substituted.<br>
</p>
<p>Mapserver has been compiled with PROJ support and a
PROJECTION has been defined for the layer in the map file.<br>
</p>
<p>The CRS of the source data is EPSG:27700<br>
</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>
<div>Thanks,<br>
</div>
<p>Andy<br>
