Aktuelle Version vom 20. April 2013, 16:11 Uhr
Programm und Open Source-Projekt für einen Kartenserver. Dieser kann - im Gegensatz zum UMN MapServer - speziell auch zur Aktualisierung von Vektordaten (WFS-T) verwendet werden.
GeoServer ist in Java geschrieben und nutzt verschiedene Basisbibliotheken, wie z.B. die Java Topology Suite (JTS). Der GeoServer kann kein WMS als Datenquelle lesen.
Siehe auch:
- Open Geo-Stack
- UMN MapServer, FeatureServer, QGIS Server, WFS-T, SLD.
- Web map caching MapProxy (Python) und MapCache (UMN MapServer) (C++).
Inhaltsverzeichnis
Software und Tools
- Homepage: http://geoserver.org
- Tiling & Caching: http://geowebcache.org/trac - GeoWebCache is a cache for WMS tiles implemented in Java
- Anwendungsbeispiel: OpenStreetMap-in-a-Box
How To Install
- run Tomcat with export JAVA_OPTS='-Djava.awt.headless=true' (see GEOSDOC)
- deploy it in webapps by moving the war file there and restart Tomcat
High performance coverage/raster data serving:
- To use a geoserver in a production environnent (i.e. with large raster data), the documentation GEOSDOC tells that the JAI extension should be natively installed.
- The documentation also says that the best file format to use is tiled GeoTIFF.
- See GDAL and GEOSDOC

GeoServer:
- Introduction to an Open Source Geostack: GeoServer
- GeoServer Workshop mit Schwerpunkt OGC WFS, A. Emde. FOSSGIS2010
Tipps & Tricks:
- java.lang.OutOfMemoryError: Java heap space problems: On JVM (within Tomcat) to "-Xms48m -Xmx256M -XX:MaxPermSize=128m"
- Given several points with a point symbolizer using an external graphic (icon), icons may overlap. How can I avoid this? Answer: SLD does not have official support for this but you can use a TextSymbolizer extension we added to get something similar. Basically TextSymbolizer in GeoServer also accepts a Graphics object, so if you use an empty label (single space using a CDATA section so that it won't be eaten away) and the graphics you should get what you're looking for.
- The way to ensure a certain rendering order is by using separate FeatureTypeStyle elements in your SLD. Put all the road outlines in a separate FTS that occurs first in the document.
- Howto use a SLD within a request? This requires some matching between the SLD and the layer. You have to give the NamedLayer the proper name: <Name>topp:shape_CH</Name> and then either: mark the style as the default one (<UserStyle> should have <default>true</default> element) - or give the user style a name and refer to it in your request (&sld=...&styles=styleName). As a final alternative, don't mention neither the layer names and styles in the GetMap request and put everything in the SLD with proper names.
