[Geoserver-devel] KML2 module: a WFS output format too
Hi, I've just written a KML WFS output format leveraging the same machinery used by the WMS output format, the output format generates the geometries and the attributes using the extended data construct, and embeds in the KML document also a schema, e.g.: ?xml version=1.0 encoding=UTF-8? kml xmlns=http://www.opengis.net/kml/2.2; xmlns:ns2= http://www.google.com/kml/ext/2.2; xmlns:ns3=http://www.w3.org/2005/Atom; xmlns:ns4=urn:oasis:names:tc:ciq:xsdschema:xAL:2.0 Document Schema id=AggregateGeoFeature_1 name=AggregateGeoFeature_1 SimpleField name=description type=string/ SimpleField name=name type=string/ SimpleField name=doubleProperty type=double/ SimpleField name=intRangeProperty type=int/ SimpleField name=strProperty type=string/ SimpleField name=featureCode type=string/ /Schema Folder nameAggregateGeoFeature/name Placemark id=AggregateGeoFeature.f005 ExtendedData SchemaData schemaUrl=#AggregateGeoFeature_1 SimpleData name=descriptiondescription-f005/SimpleData SimpleData name=namename-f005/SimpleData SimpleData name=doubleProperty2012.78/SimpleData SimpleData name=strPropertyMa quande lingues coalesce, li grammatica del resultant lingue es plu simplic e regulari quam ti del coalescent lingues. Li nov lingua franca va esser plu simplic e regulari quam li existent Europan lingues./SimpleData SimpleData name=featureCodeBK030/SimpleData /SchemaData /ExtendedData MultiGeometry Point coordinates70.83,29.86/coordinates /Point Point coordinates68.87,31.08/coordinates /Point Point coordinates71.96,32.19/coordinates /Point /MultiGeometry /Placemark /Folder /Document /kml The output format automatically skips the extra geometry attributes (which we cannot encode) and forces the output in wgs84 lon/lat as that's how KML is defined. While not as fast as GML2, it's still quite a bit faster than GML3 (tops at around 20MB/s on my machine, while GML2 goes up to 25MB/s and GML3... err... 2MB/s only...)

Re: [Geoserver-devel] KML2 module: a WFS output format too
Nice! I've always wanted that - wfs output that just removes the style. I'm curious, are you doing schema / extended data for the wms kml output? Or are they an option people can add? So you can have the styled kml with all the data? I haven't looked at KML in awhile, but I remember wanting that option or something like it.

It removes more than just the styles: * no description, GE will use the extended data to create popups if one loads the file in Google Earth * no time and elevation templates (this could be added back if needs be) * no geosearch related stuff (self links and the like) I've tried to re-create a GML like experience, but with KML syntax I'm curious, are you doing schema / extended data for the wms kml output? Or are they an option people can add? So you can have the styled kml with all the data? I haven't looked at KML in awhile, but I remember wanting that option or something like it. Yes, just add extendeddata=true in your kml reflector request and they will be generated in WMS too Cheers Andrea -- == Our support, Your Success!
