The THREDDS Data Server (TDS) provides metadata and data access to scientific datasets. Datasets can be served through OPeNDAP, OGC's WMS and WCS, HTTP, and other remote data access protocols. It can be configured to aggregate a collection of datasets so the collection is seen as a single dataset when viewed through the various data access protocols. The TDS is a server-based system that can be easily installed in any servlet container such as Apache Tomcat. We appreciate feedback from users of this package.
