DHI Clients
The Data Handling Interface (DHI) is a CORBA data access framework allowing
users to access seismic data and metadata from IRIS DMC and other participating
institutions directly from a DHI-supporting client program. The effect
is to eliminate the extra steps of running separate query interfaces and
downloading of data before visualization and processing can occur. The
information is loaded directly into the application for immediate use.
Several DHI Clients are described below.
Earth Motion Monitor
Earth Motion Monitor is a Mac OS X application that
allows browsing seismogram data available through the IRIS Data Handling
Interface (DHI) seismogram servers. Charles Ammon designed the program
to browse the data in an earthquake-centric way (as opposed to station-centric). Available
for Mac OS 10.4.x and later.
FetchResp
FetchResp is a program which will download response information from the IRIS
Network Data Center. It is intended to be run as a script either from the command
line using a terminal window or with cron using crontab.

FISSURES-MATLAB Interface (FMI)
FISSURES is an effort to define object-oriented seismic classes so that software
developers can use standard objects for seismology. MATLAB® is a scientific/engineering
computing language that is very popular among seismologists. The FISSURES-MATLAB
Interface (FMI) is an effort to build a bridge between FISSURES and MATLAB.
It allows MATLAB users to take advantage of FISSURES framework to handle seismic
data without knowing the details of FISSURES and java coding, and to easily
build their own clients.

Global Earthquake Explorer (GEE)
GEE is an education and outreach tool for seismology that aims to make it easy
for non-seismologists to retrieve, display and analyze seismic data. It is
intended for use in a classroom setting as a supplement to textbook material,
which often lacks real world connections.

JEvalResp
JEvalResp is a Java version of the 'evalresp' program and, like the original,
it is designed to evaluate the response information from ASCII "RESP" files
generated by rdseed (V4.16 and above). JEvalResp is also capable of fetching
and processing responses from FISSURES servers.
JEvalResp
JPlotResp
JPlotResp is a graphically-oriented Java program for processing and plotting
the response information from ASCII "RESP" files generated by rdseed
(V4.16 and above). JPlotResp is also capable of fetching and processing responses
from FISSURES servers.

JWEED - New Release
JWEED is a powerful, event-oriented data access tool. The application combines
an easy to use grahical user interface with an array of features
designed to aid the user in retrieving seismograms.

SAC DHI
SAC DHI allows the SAC program to connect via the Internet to the DHI online
systems. Requires SAC software.

Standing Order for Data (SOD)
SOD is a program that automates tedious data selection, downloading, and routine
processing tasks in seismology. It allows you to define your desired data based
on earthquakes, recording stations, and the resulting combination of information.

SOSA
The SOSA application (Synthetic and Observed Seismogram Analysis) combines the
common tasks of retrieving observed and synthetic seismograms and applying
analysis routines into a single software application.

SQUID - Single Query User Interface for Data
SQUID will allow users to view and manipulate PBO borehole strainmeter data.
The program will retrieve processing information, stored in XML format, and
raw SEED data from the IRIS DMC and NCEDC and will enable the user to apply
atmospheric pressure, tidal and borehole corrections to the raw data.

VASE - Stream seismograms to your computer
VASE is a Java-based client application designed for viewing and extracting seismic
waveforms from the DHI waveform repositories. In addition to streaming seismograms
in near real-time, VASE provides access to most of the archived data at IRIS. VASE
can save data to your computer in either SAC, SAC ASCII or miniseed format.
