GIS project on mapping the impacts of a proposed offshore wind development plan on Isle of Lewis communities

by Nithiya Streethran (nmstreethran@gmail.com)

Originally completed as part of my MSc dissertation at the University of Aberdeen between May and August 2021

Set-up

To execute scripts in your own Python environment, install Miniconda; choose the Python 3.9 installer.

Create and activate a virtual environment with all required packages (including QGIS):

conda env create
conda activate community-energy

To launch the QGIS GUI using this environment, run qgis. The scripts can then be copied and pasted into QGIS' Python console.

Note: Bathymetry data must be downloaded manually from the EMODnet Bathymetry portal.
