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.
