Spatial data and information processing for geomodeling

PyPI PyPI Conda GitHub Binder Read the Docs DOI

Overview

We attempt to simplify the access to open-source spatial data processing for geological modeling with the development of GemGIS, a Python-based open-source library.

GemGIS wraps and extends the functionality of packages known to the geo-community such as GeoPandas, rasterio, OWSLib, Shapely, PyGEOS, PyVista, Pandas, NumPy and the geomodeling package GemPy.

The aim of GemGIS, as indicated by the name, is to become a bridge between conventional geoinformation systems (GIS) such as ArcGIS and QGIS, and geomodeling tools such as GemPy, allowing simpler and more automated workflows from one environment to the other. This also includes making it simpler to visualize the results obtained from GemGIS and GemPy with PyVista or Blender.

Resources

Find the documentation of GemGIS here. It includes introductions to the main libraries used and to introductory topics like "What is vector data?" or "What is raster data?".

In addition, tutorial notebooks provide an overview of the different features of GemGIS. The notebooks can also be downloaded directly from here. Furthermore, many example models showcase a variety of geological structures that can be modeled with GemGIS and GemPy.

Installation

It is recommended to use GemGIS with python==3.9 in a separated environment. The main packages and its dependencies can be installed via the conda-forge channel. GemGIS is then available through PyPi. 1) conda install -c conda-forge pygeos 2) conda install -c conda-forge geopandas 3) conda install -c conda-forge rasterio 4) conda install -c conda-forge pyvista 5) pip install gemgis / conda install -c conda-forge gemgis

Check out the Installation Page for more detailed instructions.
