pyGeoStatistics

status Documentation Status

A collection of python routines (accelerated with Numba) and jupyter notebooks for geostatistics, which is immensely inspired by gslib (in Fortran).

Usage

Every routine reads its parameters from a parameter file written in json. All parameters including input/output file path need to be specified in these parameter files.

I've created scripts that assist in creating parameter files, they could be found in \parameters folder.

I tried to adhere to the naming convention of gslib when it comes to parameter names.

Markdown files describing parameters needed for each routine are in \gslib_help.

Example:

from pygeostatistics import Sgsim

sgsimulator = Sgsim("testData/test_sgsim.par")
sgsimulator.simulate()

Routines

  • eda.py: exploratory data anaylysis.

  • nst.py: apply normal score transform to data.

  • gam.py: calculate variogram for regular data.

  • gamv.py: calculate variogram for irregular data.

  • sa.ipynb: interactive structural analysis.

  • krige2d.py: kriging 2d data.

    • Simple Kriging
    • Ordinary Kriging
  • krige3d.py: kriging 3d data.

    • Simple Kriging
    • Ordinary Kriging
    • Universal Kriging (Kriging with a Trend)
    • Kriging the Trend
    • Kriging with External drift
    • SK with non-stationary drift
  • sgsim.py: Sequential Gaussian Simulation.

Other Utilities

  • super_block.py: Class for performing super block search used in kriging.

    • used in krige3d.py
    • used in sgsim.py
  • normal_score_transform.py: Class for NST used in Gaussian Simulation.

    • used in sgsim.py
