Portable Data Collection Center (PDCC)

PDCC was developed by IRIS to help network operators manage, maintain and exchange instrument response files and metadata. Through PDCC, users can build dataless SEED volumes from the Nominal Response Library’s (NRL) collection of RESP-formatted instrument response files. PDCC is also handy for editing existing dataless SEED volumes.


The installation of PDCC is easy. Since PDCC was written in Java, a platform-independent language, there is no compilation.

Download PDCC here.

Once you begin using PDCC to generate dataless SEED volumes for use in SeisComP and other seismological software packages, you will be prompted to download the NRL.

A common question: What is the difference between dataless SEED volumes and RESP files?

Whereas dataless SEED volumes contain instrument responses (poles, zeros, gains) and other critical station metadata (latitude, longitude, elevation, date of installation, modifications made, site description, …), RESP-formatted files contain only instrument response information. rdseed can be used to extract RESP files from dataless SEED volumes.

Introducing SMP

SMP is an html-based tool similar to PDCC that can be used to create station metadata files. SMP was developed by gempa.
