[Kobben, Barend (UT-ITC)]

The line
TEMPLATE "empty"

Should be
TEMPLATE "<the path to your html template file>"

Hi Users list!

I'm trying to get getFeatureRequest to reply with a html template with
pixel values from a geotiff raster image.

I have my layer like this:

   LAYER
     NAME "Overview"
     STATUS ON
     TYPE raster
     TEMPLATE "empty"
     DATA <path to my geotiff image>
     METADATA
       "wms_title" "Overview"
       "wms_timeextent" "2021-08-27T13:20:48Z/2021-08-27T13:20:48Z"
       "wms_enable_request" "*"
     END
     FILTER (`[TIME]` = `2021-08-27T13:20:48Z`)
   END

If I ask for the getcapabilities, the getfeatureinfo looks like this:

     <GetFeatureInfo>
       <Format>text/html</Format>
       <Format>application/vnd.ogc.gml</Format>
       <Format>text/plain</Format>

         </HTTP>
       </DCPType>
     </GetFeatureInfo>

And if I ask for the getfeatureinfo I get:

GetFeatureInfo results:

Layer 'Overview'
   Feature 0:

So far so good.

But now I want to add a custom template to ultimately give me a html
template with pixel values. but what ever I try to put in the TEMPLATE
variable, I dont get any other than the results shown above.

In my LAYER config I try with
TEMPLATE "http://localhost:8080/<my template name>.html"
or
TEMPLATE "<my template name>.html"

but nope.

mapserver is v7.4.3

In the documentation there is something about getfeatureinfo here
https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmapserver.org%2Fmapfile%2Fcluster.html%23handling-getfeatureinfo&data=05%7C01%7Cb.j.kobben%40utwente.nl%7Ca71634c058d2421f20d508db2c879c59%7C723246a1c3f543c5acdc43adb404ac4d%7C0%7C0%7C638152733187323138%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=uWdSh%2BNpt4m5Q2u8i39XtCWnsnbFzhrGP2DtvO1VRbA%3D&reserved=0, but
that is for cluster so I dont think it applies here.
Something more here

I don't get it.

there is also Configuring for GetFeatureInfo Requests:
Here I learned how to enable the getfeatureinfo. But the examples only
gives the replies, not how I need to setup my map file.
Also https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmapserver.org%2Fogc%2Fwms_server.html%23sample-wms-server-mapfile&data=05%7C01%7Cb.j.kobben%40utwente.nl%7Ca71634c058d2421f20d508db2c879c59%7C723246a1c3f543c5acdc43adb404ac4d%7C0%7C0%7C638152733187323138%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=8e9FKztuVma73pzpqXu8vKJtCwwtBSjdA7ndZedTjnM%3D&reserved=0
is nice, But I still don't get it.

Any advise is much appreciated.
