Python implementation of the library used to communicate seismic event detection information between systems

ANSS Data Formats

The US Geological Survey (USGS) Advanced National Seismic System (ANSS) defines a number of data exchange formats to communicate seismic event detection information between processing systems. These formats are defined using objects as defined in the JSON standard.

The purpose of this project is to:

1. Define formats to hold data representing the estimates of various types of seismic event detections.
2. Store the format definitions in a source controlled manner.
3. Host libraries used to generate, parse, and validate the formats

Defined formats:

• Pick Format - A format for unassociated picks from a waveform arrival time picking algorithm.

Supporting format objects:

• Amplitude Object - An object that contains information about an amplitude as part of a pick.
• Beam Object - An object that contains information about a waveform beam as part of a pick.
• Associated Object - An object that contains associated information if a pick is included in a detection.
• Filter Object - An object that contains filter information as part of a pick.
• Site Object - An object that defines the station used to create a pick.
• Source Object - An object that defines the creator/source of a pick.
• Quality Object - An object that defines the data quality of a pick.
• MachineLearning Object - An object that defines the machine learning information for a pick.
• EventType Object - An object that defines the event type for MachineLearning info.
