obspy.io.shapefile - ESRI shapefile write support for ObsPy

This module provides write support for the ESRI shapefile format.

Write support works via the ObsPy plugin structure for Catalog and Inventory:

>>> from obspy import read_inventory, read_events
>>> inv = read_inventory()  # load example data
>>> inv.write("my_stations.shp", format="SHAPEFILE")  
>>> cat = read_events()  # load example data
>>> cat.write("my_events.shp", format="SHAPEFILE")  

Additional information for events can be written to the shapefile as custom database columns. In this toy example we add the Flinn Engdahl region as a database column (see obspy.io.shapefile.core._write_shapefile()):

>>> from obspy.geodetics.flinnengdahl import FlinnEngdahl
>>> fe = FlinnEngdahl()
>>> regions = [
...     fe.get_region(event.origins[0].longitude, event.origins[0].latitude)
...     for event in cat]
>>> extra_fields = [('Region', 'C', 100, None, regions)]
>>> cat.write("my_events.shp", format="SHAPEFILE",
...           extra_fields=extra_fields)
