Presentation

GEOP4TH /ʤiɒpɑːθ/ jee-uh-pa-th (for GEOspatial Python Pre-Processing Platform for Trajectories in Hydro-socio-ecosystems) is a collection of generic, format-agnostic, python tools (geobricks) designed to easily standardize, manipulate and visualize space-time data.

Besides, these geobricks are designed to be assembled into complete pre-processing workflows for specific data or to specific models. Such workflows can be collaboratively developped and shared within GEOP4TH. So far, GEOP4TH includes the workflows for pre-processing some of the most common French datasets (SIM2, DRIAS/EXPLORE2, BNPE, IGN...), as well as the workflows to format inputs for CWatM. Collaborative developments are welcome :)

In the end, GEOP4TH intends to help working on hydro-socio-ecosystems trajectories and diagnostics.

Getting started

Note
Latest quickstart instructions are described in the Documentation with more details.

Installation requirements

To install the python environment required to use this module, it is necessary to install an Anaconda distribution (such as Miniconda3).

Tip
For a start, we also advise using a Git Management tool (such as GitHub Desktop).

Retrieve this remote git folder to a local machine

To clone this git folder using for example GitHub Desktop, you can:

1. Go to File > Clone repository...
2. Got to URL tab and enter https://gitlab.com/AlexandreCoche/geop4th.git
   • the local path should end with geop4th

Python environment

GEOP4TH requires some common open-source python packages (xarray, rioxarray, rasterio, numpy, pandas, geopandas, shapely, fiona, pysheds, plotly, matplotlib).

Installing the python environment can be done in the conda console (admin mode advised) by entering:

# If geop4th has been cloned to another disk than C:, it is necessary to enter the name of the disk first
# d: (for example)
cd "path/to/geop4th/install"
conda env create -f environment.yml -n geoenv

Set up

1. Open conda prompt and activate environment:

conda activate geoenv

2. Install and open an IDE such as Spyder or Jupyter Notebook:

conda install spyder -c conda-forge

spyder

3. Once in the IDE, the parent folder (the root folder containing geop4th folder) should be added to the PYTHONPATH

4. Then, the main modules can be imported as follow:

# Basics elements
from geop4th import (
    geobricks as geo,
    download_fr as dl,
    trajplot as tjp,
    )
	
# or complete workflows
from geop4th import (
    standardize_fr as stz,
    cwatm,
    )

Docker image

A Docker image of 0.10.1 version is available here: https://hub.docker.com/r/alexandrecoche/geop4th.

Project status

Currently under developpement.

Roadmap

• generalize data paths in trajplot and document it
• document all the functions
• implement logging everywhere and add a workflow log
• implement a comparison function
• for contributing, test and resolve the installation procedure with pip
• clean code (functions in geohydroconvert #%% EXTRACTIONS, georef in double, clean comments, restructure SIM2_tools and advanced_visualization into geohydroconvert...)

Authors and acknowledgment

This work has been created by Alexandre Kenshilik Coche, with the help of the following first contributors: The design of the trajplot figures was conceived with the help of Laurent Longuevergne, Elias Ganivet and Veronique Van Tilbeurgh.
Part of the functions to handle SIM2 data were conceived with the help of Ronan Abhervé and some code parts from Loïc Duffar's scripts.
Packing functions were based on James Hiebert's work. Alexandre Gauvain shared insightful ideas on how to structure the gitlab and the ReadTheDocs documentation. Bastien Boivin and Pape Saara Ngom provided helpful advice to improve the installation procedure. Damien Belvèze and Martin Komlavi Amouzou brought a significant help and crucial advice on software development good practices, replicability, testing and containerization. Programmer web communities brought a considerable help to this work.
