DASPy

DASPy is an open-source project dedicated to provide a python package for DAS (Distributed Acoustic Sensing) data processing.

The goal of the DASPy project is to lower the bar of DAS data processing. DASPy includes:

• Classic seismic data processing techniques, including preprocessing, filter, spectrum analysis, and visualization
• Specialized algorithms for DAS applications, including denoising, waveform decomposition, channel attribute analysis, and strain-velocity conversion.

DASPy is licensed under the MIT License. An English version of DASPy tutorial, a Chinese version of DASPy tutorial and an example of Jupyter notebook is available. If you have any questions, please contact me via hmz2018@mail.ustc.edu.cn.

Installation

DASPy runs on Linux, Windows and Mac OS and on Python 3.9 and up.
