[Zoo-discuss] ZOO Project with MapServer (WIndows 10)

Sun Jul 1 23:07:25 PDT 2018

I have got MapServer working fine now. Thanks for the help.

I finally ended up passing GML3 to generate the mapfile from the WPS
service with MapServer. The problem is that this mapfile does not seem to
support WMS GetFeatureInfo. Are there some additional configuration steps
required to add that? (The generated mapfile does not contain any TEMPLATE
element.)

Please Help. Thanks in advance
