Input to PRISM currently is limited to data files in the Consortium of Organizations for Strong-Motion Observation Systems (COSMOS) V0 format, so that all retrieved acceleration time series need to be converted to this format. PRISM was designed to be flexible and extensible in order to accommodate implementation of new processing techniques. To facilitate the use by non-NSMP earthquake engineers and scientists, PRISM (both its processing engine and GUI components) is easy to install and run as a stand-alone system on common operating systems such as Linux, OS X and Windows. The software consists of two major components: a record processing engine composed of modules for each processing step, and a graphical user interface (GUI) for manual review and processing.
The PRISM software is platform-independent (coded in Java), open-source, and does not depend on any closed-source or proprietary software.
PRISM automates the processing of strong-motion records by providing batch-processing capabilities.
The NSMP has developed the Processing and Review Interface for Strong Motion data (PRISM) software to meet this need. Geological Survey (USGS), as well as data from regional seismic networks within the U.S., calls for automated processing of strong-motion records with human review limited to selected significant or flagged records.
