Support for obspy Catalog and Inventory objects

[d-chambers]

Hello,

Thank you for sharing this package, it looks awesome.

Does pisces support obspy Catalog objects (for event data) and obspy Inventory objects (for station data)? I am imagining an API similar to the obspy fdsn client class. For example, the event functionality might look like the following:

import pisces
catalog = pisces.get_events(minmagnitude=4)  # pull events out of the db
for event in catalog:
    make_some_changes(event)  # process the events in some way
pisces.put_events(catalog)  # update all of the modified events in the database

Thanks again.

Thanks, @d-chambers ! The current answer is "no", but I definitely want to implement an Obspy-like Client , where c.get_events returns a Catalog, c.get_stations returns an Inventory, and c.get_waveforms returns a Stream. I'm mostly sure that ObsPy Clients have an API that looks like the FDSN-WS spec, but I don't currently have the know-how to implement a Client that fully follows that spec. Assembling Catalog and Inventory objects from database queries is something that needs to happen, though. PRs are encouraged! 😄

@klaaur Do you have any progress on this?😋

Yes, we ended up not getting an intern so it’s still in the same state. Will check with some people at SNL about sharing and keep you posted. I should push another thing to your git page to inform you that you can no longer import obspy.taup in your util.py file in obspy 1.1.0- haven’t looked up the correct call yet but should be easy to track down.

Thanks for looking into it. Re: obspy.taup, I just pushed a Python 3 version that includes the taup fix. Downside (upside): the new version is Python 3 only.

This feature will be helpful for me as well. Is there any chance that there's been a progress on this one? I couldn't find it in the docs.

I might be able to help if needed.

@rigotibi I know you were interested in this topic. I just want to tag you on it here for visibility.

@zvikfir I'm sorry for the delay in responding. There isn't anything new on this topic, except that there are a number of interested parties. Thank you for your offer to contribute. Are you interested in the Catalog or Inventory objects, or both?
