Software for accessing data in near real-time

Q: I'm working on a project in where we want to display seismic data in real-time. We are interested in two stations to begin with 223.TA and 324.TA eventually we will have more stations. I would like to know if this data can be display in real-time with the software you have in your web site.

Do you have any software that can display seismic data in real-time?

A:


SeedLink service - A TCP/IP based protocol designed to robustly deliver real-time, continuous data over the Internet. The robust nature of the protocol allows clients to disconnect and reconnect without losing data (reconnection must happen within a reasonable amount of time, i.e. a couple of hours). The requested data streams may be limited to specific stations, locations and/or channels. Very little data latency (seconds) is introduced relative to the real-time data streams coming in to the DMC, all latency variations are due to the DMC's upstream source. SeedLink is developed by GEOFON. For more details see the DMC SeedLink overview.

SeisGram2K - For the display of SeedLink data feeds, we like to use Anthony Lomax's SeisGram2K utility.


VASE is a Java-based client application designed for viewing and extracting seismic waveforms from the DHI waveform repositories. VASE manual

We have a policy for expectations of real time data availability that is worth consulting to understand our mission goals in providing real time data to users.
