On-line analysis is provided, powered by the R Statistical environment.
METAMOD is a portal solution providing Discovery, Access and Retrieve functionality for scientific datasets along with tools for DAR metadata like automatic extraction, manual editing, and conversion between different formats.

It has been designed to be easily integratable with OpENDAP or FTP data servers, and allows data to be uploaded through FTP and HTTP interfaces. A WMS client is built in for visualizing the data.
