The Scripps Orbit and Permanent Array Center (SOPAC) has completed development of
a first-generation software package for accessing the GPS Seamless Archive (GASC).
The GSAC is a one-stop virtual archive of GPS data, metadata, and products
composed in large part of data collected by U.S. scientists and their
collaborators over the period 1986 to the present in Western North America and other
tectonically active regions around the globe, as well as the holdings of two Inter-
national GPS Service (IGS) global data centers. By providing access to six different
archives in North America (i.e., the "GSAC Wholesalers"), these software tools make available
more than 2 million GPS data files pertaining to over 10,000 different geodetic monuments.
The software provides three different types of user interfaces: the interactive GSAC
Wizard (CGI), a command-line Unix-style execuatble called gsac-client, and a front door HTTP
service called the GSAC Retailer Service Interface.
