I should have added that the behaviour is the same if the template file is configured as an OUTPUTFORMAT.

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.
I have a test template file as follows:
<!-- MapServer Template --> <p> Map X/Y : [mapx],[mapy]<br> Map LL : [maplon],[maplat] </p>If I configure an 'old style' TEMPLATE in the map file, directly referencing the html template as follows:
LAYER TEMPLATE "coord_comp.html"With a GFI request specifying a CRS of EPSG:27700:
...&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=50the output of is as follows:
Map X/Y : 390428.846605,68589.162768
Map LL : 50.516415,-2.135015When a similar requests are made specifying a CRS of EPSG:4326:
...&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=50the output is as follows:
Map X/Y : 50.514437,-2.120136
Map LL : [maplon],[maplat]The maplat and maplon templates are not substituted.
Mapserver has been compiled with PROJ support and a PROJECTION has been defined for the layer in the map file.
The CRS of the source data is EPSG:27700
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?
Thanks,
Andy
