NetDC available at the NCEDC

January 23, 2000NetDC (Networked Data Centers), a system that allows users to easily and transparently request and retrieve information about seismic and geophysical network data from multiple data centers, is now available at the NCEDC.
A NetDC request is a simple text request file that is emailed to any NetDC data center. NetDC will either email the response back to the user, or place the response in anonymous ftp for the user to retrieve, and notify the user via email with the location of the response. NetDC provides the structure for data centers to communicate requests from users to the appropriate data center that can satisfy the users's request, and will route the response back to the user.
NetDC incorporates all of the BREQ_FAST data request capabilities, and allows user to request other types of information about networks, stations, and channels. A NetDC request can be used to retrieve the following types of information:
Inventory information - list of data centers, list of networked serviced by each data center, list of stations, list of channels, and list of waveforms available within a specified time window.
Instrument response in ASCII format for specified data channels and time windows.
Waveform data for specified network, station, channel, location, and time window.
Data from the BK (Berkeley Digital Seismic Network/Northern Hayward Fault Network/Mini Plate Boundary Observatory Project), BP (High Resolution Seismic Network), and UL (USGS Low-frequency network) networks are available using NetDC at the NCEDC. Work is underway to make the NC (USGS Northern California Seismic Network) data available from NetDC.
NetDC may be used to access data from the NCEDC in two different ways. Users may email their NetDC requests to netdc@ncedc.org or may use the NCEDC waveform request form, which is a web interface for for users to query the NCEDC waveform inventory, create, and submit a NetDC request.
