georesistpy 0.2.0

Python library for Electrical Resistivity Tomography (ERT) data processing with Web UI

GeoResistPy

Python library for Electrical Resistivity Tomography (ERT) data processing

GeoResistPy provides a complete, workflow-based toolset for 1D Vertical Electrical Sounding (VES) and 2D resistivity imaging — similar to professional software such as RES2DINV or BERT, but built entirely in Python with a modern web UI.

Features

Area	Capabilities
Data Import	CSV, TXT, ABEM, Syscal, generic spacing tables
Quality Control	Negative-resistivity removal, outlier filtering, reciprocal error analysis
Survey Config	Wenner, Schlumberger, Dipole-Dipole, Pole-Dipole, Pole-Pole
Forward Modelling	1D layered earth, 2D resistivity (pygimli / SimPEG)
Mesh Generation	Adaptive triangular mesh with electrode & depth refinement
Inversion	1D VES, 2D ERT — smooth / robust (L1), L-curve, auto-λ
DOI	Sensitivity-based depth-of-investigation index
Visualization	Pseudosection, inverted section, residuals, sensitivity (Plotly / Holoviews)
Web UI	Panel dashboard with 7 workflow tabs
Export	CSV, GeoTIFF, PNG, NetCDF

Quick Start

# Install (editable, with all extras)
pip install -e ".[all]"

# pygimli must come from conda-forge
conda install -c conda-forge pygimli

# Launch the web UI
python -m georesistpy.app
# → opens http://localhost:5006
