Data Archive Interface Version 2 (DAIv2) - Public Alpha Release

Data Archive Interface Version 2 (DAIv2) - Public Alpha Release

November 6, 2008

The Data Archive Interface Version 2 (DAIv2) is the UNAVCO Facility's next generation interface for search and access of UNAVCO's GPS data holdings. The DAIv2 includes a powerful and flexible Web application (see figure 1) for discovery and visualization of UNAVCO's GPS data and metadata holdings. The DAIv2 also includes a suite of Java-based command-line clients for advanced users needing automated discovery and download (see figure 2). Both the Web application and the command-line clients utilize our new Web services infrastructure.

GGN Station Install, Falkland Islands

GGN Station Install, Falkland Islands

August 26, 2008

NASA-JPL provides support for the GPS infrastructure through a network of permanent GPS stations called the Global GPS Network (GGN). The UNAVCO Facility supports the operation and maintenance of the permanent stations that make up the NASA-GGN. In order to increase the coverage of the GGN network, a new station (FALK) was added in Port Stanley, Falkland Islands, a United Kingdom territory. The islands are located about 500 km off the eastern tip of South America in the South Atlantic Ocean and this new GPS station location fills a previous gap in the GGN-GNSS network.
