Maryland Department of Natural Resources  Seismic Network
Components   The seismic network consists of a remote sensing
station, equipment to transmit and receive data, a computer to
log and display the data and an Internet connection to
distribute the data. Signals from the seismometer are sent via a
transmitter at Soldiers Delight to a receiver on the roof of the
MGS building. From the rooftop receiver, the data signal is sent
to a dedicated computer for processing, display and storage. The
data is then made available on the Internet from our World Wide
Web site.  Seismic network data path   Data Collection and
Processing  The Maryland Seismic Network uses a variety of
software to collect, analyze and display data. Some of this
software was developed by MGS, and some came from other
sources.  Earth movements are detected by the seismometer and
converted to a digital signal by the instrument's internal
digitizer. The digitizer also compresses the data before it is
transmitted to the Survey laboratories. The
