Technical Meeting on SHI Software Engineering


This meeting will be held in a hybrid format

Vienna International Centre
Vienna, Austria

24-25 June 2024

The working language will be English

This meeting allows States Signatories to learn about software development efforts at the IDC, with a focus on waveform technologies. Several efforts are ongoing to improve the software in use at the IDC, and NDC software shared with States Signatories via NDC-in-a-Box.

The PTS is currently in the implementation phase of the IDC SHI Reengineering program, which includes a large-scale effort to improve the SHI processing system, State of Heath, and the Analyst Interface. The goal remains to develop a modern, maintainable, and open-source SHI data processing system. Progress is ongoing, and many states have participated in the Alpha Testers Group for Reengineering.

Meanwhile, several other software development efforts have led to improved IDC product distribution, NDC-in-a-Box (NIAB), routine data processing, and processing for Expert Technical Analysis. 

This meeting allows experts to discuss such software updates in depth and provide review and feedback. 
This technical meeting will focus on: 

  • Reviewing status of work on Reengineering, including progress updates, and discussion of the project plan, projected milestones, and updated deliverables.
  • Updates on testing and use of NetVISA, Threshold Monitoring, RSTT, and F-detector, and use of HPC.
  • Recent updates to Product Distribution, VDMS, FDSN and NIAB.
  • Discussion of other software efforts to update and improve SHI processing.

Meeting participants are invited to contribute to the technical meeting by making a 20-minute presentation related to one of the following themes:

Theme 1
IDC Reengineering Project Status, Experiences of Alpha Testers Group, NDCs engagement with Reengineering.

Theme 2
Improvements of SHI processing, data product and distribution at the IDC

Theme 3
Technical and Scientific Ideas to improve SHI processing

To be provided in due time


  • Experts responsible for the software development for waveform monitoring at the National Data Centres.
  • Experts involved in software development for environmental monitoring applications, particularly in waveform methods, including signal processing, user interfaces, database systems. 
  • Participants should have in-depth knowledge of at least one aspect of SHI data processing at the IDC.


Applicants are requested to visit our website and apply online latest by 30 April 2024.
