5.7 SEED name mappings

Several seismic network formats use the FSDN SEED naming
convention to identify channels.

Before you can connect Güralp Systems instruments to a network

using this convention, you will need to define mappings between the
raw stream names from the digitizer (

e.g. DEMOZ2) and the FSDN SEED

names for the same streams (

e.g. GB:GSL:BHZ).

This mapping is defined in an XML file stored at
/etc/seedmap2.xml. Clicking on Data transfer – SEED name

mappings opens a page allowing you to view and edit the mapping.
