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>
<DCPType>
<HTTP>
<Get><OnlineResource
xmlns:xlink="http://www.w3.org/1999/xlink";
xlink:href="http://localhost:8080/mapserverapi?"/></Get>
<Post><OnlineResource
xmlns:xlink="http://www.w3.org/1999/xlink";
xlink:href="http://localhost:8080/mapserverapi?"/></Post>
</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://mapserver.org/mapfile/cluster.html#handling-getfeatureinfo, but
that is for cluster so I dont think it applies here.
Something more here
https://mapserver.org/ogc/wms_server.html#how-does-a-wms-work, but still
I don't get it.
Some lines after
https://mapserver.org/ogc/wms_server.html#setup-a-mapfile-for-your-wms
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://mapserver.org/ogc/wms_server.html#sample-wms-server-mapfile
is nice, But I still don't get it.
Any advise is much appreciated.
