[mapserver-users] no result with getFeatureInfo text/plain

Wed Jun 10 08:15:40 PDT 2015

Hi,

Definitely, not sure about that. It can be a feature if you are both configuring Mapserver and building/controlling the applications which are using the service. If you just offer a WMS service for the public your users can't imagine that changing info_format in the client settings may have an effect on the data that is returned with GetFeatureInfo.  Consider GetMaps with image/png vs. image/jpeg or WFS GetFeature output as GML vs. GeoJSON.

Because attributes are different then MAP level setting could only have options "all" or "none".  Current situation means practically having "none" as a default for all layers. So the advantage would be an option to set the default to "all" for every layer in the service and Mapserver admin should remember to think if GetFeatureInto output should be restricted somehow for the new layers.  That does not feel like a big saving in labour.

What could save labour would be to generate automatically a template that would show all the fields which are listed in the "ows_include_items" in a simple default html table. Keyword for activating it could be "TEMPLATE" "AUTO" or something like that. I suppose that Geoserver is doing it that way http://docs.geoserver.org/latest/en/user/tutorials/GetFeatureInfo/index.html

You do have "ows_include_items" at MAP level but it does not have any effect there. On the other hand, "ows_include_items" does not have any effect on the text/html output but that can only be adjusted by editing the template. For sending out the same information with text/plain and text/html the Mapserver admin must make edits in two different places - ows_include_items and the template. I am not sure if this should be considered as a bug or a feature but at least it is confusing.
