pygef 0.8.0a2

Parse soil measurument data.

PYGEF

Simple parser for *.gef files. These are ASCII based files used for soil properties measurements. Compatible with Python 3.7.

Recently added the parsing of xml boreholes file, the xml parsing is still in a preliminary phase, not all the files are supported. If you find a file that doesn't work with pygef, please make an issue about it or PR :)

Installation

Latest stable version:

$ pip install pygef

Cutting-edge version (might break):

$ pip install git+https://github.com/cemsbv/pygef.git

>>> # read gef and xml files
>>> cpt_data = read_cpt("./my-cpt.xml")
