NSMP Project

• NSMP software written in 1992.
• Generates response and Fourier spectra, corrected
  acceleration, velocity, displacement

NSMP Project

• BAP uses file-based I/O and configuration
• 2-byte precision output and therefore duplicated
  at CESMD
• Poor interface to ANSS data
• NSMP project recently reorganized
• Data acquisition/processing in NCSN
• Field installation/maintenance in Earthquake
  Effects Project

5
Goals

• Migrate NSMP post-processing algorithms into CISN
  software architecture with effective
  user-interface tools
• Provide a supported, stable, and efficient
  processing platform for generating processed
  strong-motion records.
• Ensure that migrated software is capable of
  meeting present and future needs of ANSS, NSMP
  and the COSMOS user community.
