A Python interface to compute biodiversity metric based on landscape elevational connectivity.
Project description
bioLEC - Biodiversity metric based on landscape elevational connectivity
This folder contains notebooks to compute landscape elevational connectivity described in Bertuzzo et al. (2016) using a parallel LECmetrics python code.
Binder
Launch the demonstration at mybinder.org
Navigation / Notebooks
Examples
Notebooks environment will not be the best option for large landscape models and we will recommend the use of the python script: runLEC.py
in HPC environment. the code will need to be
mpirun -np 400 python runLEC.py
The tool can be used to compute the LEC for any landscape file (X,Y,Z) and IPython functions are provided to extract output data directly from pyBadlands model.
Installation
Dependencies
You will need Python 2.7 or 3.5+. Also, the following packages are required:
Installing using pip
You can install bioLEC
using the
pip package manager
with either version of Python:
python2 -m pip install bioLEC
python3 -m pip install bioLEC
Installing using Docker
A more straightforward installation which does not depend on specific compilers relies on the docker virtualisation system.
To install the docker image and test it is working:
docker pull geodels/biolec:latest
docker run --rm geodels/biolec:latest help
To build the dockerfile locally, we provide a script. First ensure you have checked out the source code from github and then run the script in the Docker directory. If you modify the dockerfile and want to push the image to make it publicly available, it will need to be retagged to upload somewhere other than the GEodels repository.
git checkout https://github.com/Geodels/bioLEC.git
cd bioLEC
source Docker/build-dockerfile.sh
Usage
A series of tests are located in the tests subdirectory.
