You can link your own map data from your own map server to Google Earth using KML... it's pretty cool.

FAO-UN released a pretty neat package called GeoNetwork. It is a web based Geographic Metadata Catalog System. The system implements the ISO 19115 Geographic Metadata and ISO 23950 (Z39.50) standards. Technical details: Java, XML/XSL, JDBC compliant, Multi-lingual support, etc.

You can download GeoServer via the following link:

GeoServer is an Open Source server that connects your information to the Geospatial Web.

With GeoServer you can publish and edit data using open standards. Your information is made available in a large variety of formats as maps/images or actual geospatial data. GeoServer's transactional capabilities offer robust support for shared editing. GeoServer's focus is ease of use and support for standards, in order to serve as 'glue' for the geospatial web, connecting from legacy databases to many diverse clients.

GeoServer supports WFS-T and WMS open protocols from the OGC to produce JPEG, PNG, SVG, KML/KMZ, GML, PDF, Shapefiles and more. More information on specific features of GeoServer can be found here, and some samples of GeoServer in action are in the gallery.

Geoserver is built on Geotools, the same Java toolkit that udig uses. GeoServer is a truly open community, with a well documented and modular codebase, so don't hesitate to get involved.
