GeoDAS is a graphical Microsoft Windows-based application running under Windows XP / Vista / 7 / 8.
It provides the most comprehensive, intuitive and versatile features available in the earthquake, seismic, structural, dynamic and static monitoring and measuring industry.
Fundamentally the program is used for instrument configuration and for acquisition of data provided by any standard GeoSIG instrument.
GeoDAS Features the following basic functionalities (within GeoDAS-BASE and GeoDAS-COM packages):
• Instrument setup to change any configuration parameters of any instrument(s)
• State of Health (SOH) monitoring for permanent or periodical monitoring of instrument/system status
• Downloading of the event files from recorder(s)
• Real-time data viewer and recorder for instrument(s) providing data streams
• Off-line data viewer
• Convert/Export to ASCII, SUDS, SAC, SEISAN, ARTeMIS, MATLAB
• Logger features to store important system messages in a log file
• Station Map
• Network Monitor
• Network Links
• Messenger
• Statistics of Communications
The GeoDAS-BASE package is the basic software package which is also downloadable here.
The GeoDAS-COM package includes the GeoDAS-BASE package and specific basic cables and hardware certified to use with the relevant equipment supplied.
The Data Analysis part of GeoDAS (GeoDAS-DAP) has been developed by GeoSIG especially for the strong motion, earthquake engineering and civil engineering data analysis. The following operations can be performed:
• Lowpass Filter
• Highpass Filter
• Baseline correction
• Integration
• Differentiation
• Vector Sum
• Cumulative Absolute Velocity (CAV)
• Time-domain Filtering
• Effective Values
• Damping
• Power Spectra
• FFT Magnitude
• Terzband Spectra
• Response Spectra
• JMA Intensity
• STA/LTA Ratio
• Signal Characteristics
• Analysis Templates
The general functionality of GeoDAS briefly described above is used in most applications based on GeoSIG equipment.
Moreover special GeoDAS versions (i.e. GeoDAS-AEP, GeoDAS-NPP, etc) offer special functions, some of which are supplied for particular applications or some of which can be activated in special cases only. These functions include, but are not limited to:
• Strong Motion Data Processing
• OBE / SSE Event Checks
• Support for ADC Boards
• Static Measurements
• Automatic Event Processing
• Automatic File Conversion |
