Building network metadata - CSS3.0

This tutorial demostrates the basics of building network geometry for a CSS3.0 database (suitable for use with Antelope software).

import seispy

# Instantiate an empty Catalog
cat = seispy.pandas.catalog.Catalog()
# Add station PFO to the site table:
cat.add_row("site",
            dict(sta="PFO", ondate=1982274, lat=33.6117, lon=-116.459, elev=1.259, staname="Pinon Flats Observatory, CA, USA"))
# Add channel metadata for station PFO to the sitechan table:
for chan, hang, vang in (("HHZ", 0, 0), ("HHN", 0, 90), ("HHE", 90, 90)):
    cat.add_row("sitechan",
                dict(sta="PFO", chan=chan, ondate=1982274, edepth=0.005, hang=hang, vang=vang))
# Add station BALD to the site table:
cat.add_row("site",
            dict(sta="BALD", ondate=2012268, offdate=2018365, lat=33.6811, lon=-116.742, elev=1.57, staname="Baldy Mountain, CA, USA"))
# Add channel metadata for station BALD to the sitechan table:
for chan, hang, vang in (("EHZ", 0, 0), ("HHN", 0, 90), ("HHE", 90, 90)):
    cat.add_row("sitechan",

# Write CSS3.0 format database files to disk:
cat.write("/path/to/output/db")
