[mapserver-users] MapServer output
I have been using MapServer for sometime now, but doing really simple things with it... read in mostly Pg, Shapefile and raster data, and output mostly images via regular CGI or WMS. One thing that GeoServer seems to do very well is provide easy output to a variety of formats -- GeoJSON, images, features, KML, a whole lot more. What are MapServer's capabilities in this regard? Ideally, my application would return the requested format based on the URI. So, given http://server/mapserv/wms/ would return WMS. If I replace wms with kml I would get back KML, or replace it with geojson and get back GeoJSON, etc. Is there a tutorial or documentation on this that someone can point me to? -- Puneet Kishor http://www.punkish.org Carbon Model http://carbonmodel.org Charter Member, Open Source Geospatial Foundation http://www.osgeo.org Science Commons Fellow, http://sciencecommons.org/about/whoweare/kishor Nelson Institute, UW-Madison http://www.nelson.wisc.edu --- Assertions are politics; backing up assertions with evidence is science === ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [mapserver-users] MapServer output
Hi, Geoserver can generate GeoJSON, KML and zipped shapefiles as alternative WFS outputformats in addition to gml that is mandatory according to standard. Mapserver generates gml if configured to work as WFS server, and KML support seems to be available by defining it as an outputformat in the mapfile, see http://mapserver.org/development/rfc/ms-rfc-58.html And see the vector outputformat in Mapserver 6.0 http://mapserver.org/trunk/output/ogr.html So you can already get some of the extra formats which are supported by Geoserver, and most/all/even more in the future. However, configuring will be more complicated than with Geoserver which has a nice GUI tool for configuring all the WMS, WFS and WCS services at the same time. -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: P Kishor Lähetetty: pe 19.11.2010 19:38 Vastaanottaja: Mapserver-users Aihe: [mapserver-users] MapServer output I have been using MapServer for sometime now, but doing really simple things with it... read in mostly Pg, Shapefile and raster data, and output mostly images via regular CGI or WMS.

Yeah, I played with GeoServer a while back. Then I saw it again yesterday and its output capabilities were just wonderful. However, I am allergic to Java, so I want to stay away from Tomcat and Jetty and such nonsense unless MapServer is absolutely unable to deliver.

RE: [mapserver-users] MapServer output
I believe Frank's work extends beyond WFS as well to standard MapServer queries, or if that's not possible yet it can be. Remember also that you have query templates at your disposal which can be used to generate any number of text-based formats.

Steve, Yes, I an confirm that it is tied into the standard query mechansism. It also can work for WMS GetFeatureInfo requests. I have actually tested WMS GetFeatureInfo and WFS GetFeature, but I have not tested it in the context of other sorts of queries.

In 6.0 all the renders are now in a plugin format which will make it easier to add new renderers and make it easier to maintain existing renderers to keep them more consistent. I think it also improves the query output to some extent because that is based on how renders work. In one sense rendering is what mapserver does. in some cases it renders as an image, in other cases it renders as text or other formats. I think the other responses to this thread pretty much covered the details of what you can do now and the additional query responses based on 6.0 code. -Steve W Also, mapserver support OGC WFS and I think there may be options to configure the output as XML or JSON, but I'm not sure.

It does a query and generates multiple layer/feature KML file via a template... The output is compressed across the wire (thanks to mod-deflate) but appears uncompressed to the user when the file arrives.
