The DMC has developed three Sync file based tools to help with QC of the data stream into and out of the DMC.

GOAT - this starting point lets a user upload and display their own sync file. The display shows gaps, overlaps, and continuous time spans in a color coded graphical and tabular form.

Sync file query - creates a Sync file from the data holdings in the DMC's database. After doing the query, the resulting Sync file may be displayed with GOAT or a user may go to Combine, upload their own Sync file, and compare it with the Sync file from the query. This is the starting place to compare what a data provider has in their database with what the DMC has in it's database.The Combine display shows common data and data which is missing from each file in a color coded graphical and tabular form.

Combine - this starting point lets a user upload their own sync file and do a comparison of it with a Sync file previously created with the SeismiQuery Timeseries query.
