Tools for sub-surface geophysical survey data processing

Project description

PyPI - License PyPI PyPI - Python Version PyPI - Downloads

GeophPy is an open source python package that offers tools for sub-surface geophysical survey data processing.

It mainly focuses on ground surveys data and offers tools to process the data and create geophysical maps that can be imported to GIS softwares.

GeophPy contains general tools, such as data destaggering, destriping and method-specific tools, such as reduction to the pole or magnetic data continuaiton.

Main Features

  • Build dataset from one or severals data files.
  • Display geophysical maps in 2-D or 3-D.
  • Processing datasets with general or method-specific geophysical processing step.
  • Export processed datasets into georeferenced format compatible with any GIS.
  • Compatible with Python 3.x.

Installing

GeophPy is distributed on the PyPI repository and you can install it using pip.

>>>  pip install geophpy
>>>  or
