Introduction

Welcome to the GSAC Wizard v1.2

Using this Wizard you can browse GPS Seamless Archive Center (GSAC) content (monuments or data files) by adding/subtracting various constraints in an interactive query-building process.

Please be advised that this tool is just one way to access the GSAC, and was designed primarily for the discovery, summary and quality-checking of GPS monument metadata. Though you can also locate data records with this tool, using most of the same criteria, users should exercise caution when building queries (for data records) with long timespans and/or large spatial extents. Since there are more than 4.5 million data records now available in the GSAC such large queries will take time to execute, and, will often return extremely large data sets (several thousand records or more).

Warning

On some Netscape 4.x browser platforms this application may be extremely sluggish between page loads. This problem has been investigated and no solution has been found, as yet. We suggest you try Netscape 6.x, Mozilla, or Internet Explorer in the meantime.

Throughout your Wizard session various results, information and dynamic content will appear in this box for your information.
