bezpy 0.1.1

Bezpy

Bezpy is an open source library for analysis of geomagnetic (B), geoelectric (E),
and magnetotelluric impedance (Z) data within a geophysical framework.
This library contains routines for calculating the geoelectric field from the geomagnetic field in
multiple different ways.
Features

Geomagnetic to geoelectric field calculations
Integration of the geoelectric field along transmission lines
Built using established, fast, open source python libraries
Pandas,
NumPy,
SciPy

Examples
Example notebooks can be found in notebooks/
Example scripts for command line use can be found in scripts/
Install
The easiest method to install bezpy is directly from PyPI using pip.
pip install bezpy

If you want a local install to modify anything in the code, you
can clone the git repository and install locally with these commands.
git clone https://github.com/greglucas/bezpy
cd bezpy
pip install .
