Portable Data Collection Center PDCC v3 8 User Manual Robert Casey IRIS DMC January 2012 RIS i INTRODUCTION The purpose of PDCC is to enable seismic network operators to describe and maintain their instrument metadata in SEED format This in turn allows effective data interchange in an environment of continually changing instrument deployments This tool is designed to make the process of creating metadata descriptions easy though some knowledge of the SEED data format is recommended PDCC consists of a main editor window for reading viewing and writing out dataless metadata only SEED files and has a connector to specialized tools that facilitate the construction of metadata entries from external sources PDCC represents a continued effort by IRIS to support the seismological community with tools to enable data collection and research WHAT IS NEW PDCC 3 8 introduces an updated Station Clone Tool that allows the user to create new stations and modify critical differentiating fields in a simple tabular entry form The SEED Data Browser tree shows blockettes in an easier to read format Recovery of a lost editing session is possible through the use of the Journal File load feature This is still experimental and not guaranteed to provide complete recovery Volt units are asserted in the Channel Input Calibration Units field when creating a new channel Confirmation dialog when user attempts to exit PDCC SYSTEM REQUIRE
