Hi there, currently I'm working on an OpenSource WebGIS, in which a large amount of line-objects (about 15 000) have to be displayed over the map of Germany. The data is distributed via GeoServer 2.1.3 WFS and is displayed in an OpenLayers Client (Version 2.11). The data is stored in a PostGIS-database. Because of the huge data and the high grade of detail of the lineobjects, the application takes much time to display the vectordata in small scales (>1:1 000 000).
To deal with this problem I would like to use the "GeoServer pregeneralized features"-extension. I've already generalized the data and followed this tutorial (http://www.mail-archive.com/geoserver-devel@lists.sourceforge.net/msg10382.html) to create a "generalized datastore" in GeoServer. The configuration part went well. But when I try to view the generalized layer in OpenLayers, I get the following message in the GeoServer-Log: „WARN [org.geotools.data.gen] - No hint for geometry distance in query, fallback to base feature“ This means, the layer is displayed correctly, but always with the base geometry. I get the same message when following the tutorial from the GeoServer website (http://docs.geoserver.org/stable/en/user/tutorials/feature-pregeneralized/feature-pregeneralized_tutorial.html) and generating a generalized data store from a shape file, so it's not a problem with the PostGIS-database. I've read in the Geotools-documentation (http://docs.geotools.org/latest/userguide/library/data/pregeneralized.html) that the additional hint "GEOMETRY_DISTANCE" has to be passed to the WFS-query. Does anybody know how to configure the OpenLayers-client to be compatible with the GeoServer pregeneralized features extension? Thanks alot.
