fire2a-lib python package

Fire Advanced Analyitics research group scriptable knowledge base

• Novel Algorithms related to landscape risk metrics, spatial decision optimization models, etc.
• (Cell2) Fire (W) Simulator integration algorithms to facilitating placing firebreaks, measuring forest fire impacts, etc.
• (Q)GIS algorithms to common tasks related to rasters, polygons, spatial clustering, etc.

Quickstart

Simplest: Use within QGIS

1. Install QGIS
2. Open QGIS Python Console
3. Type (to install)::

!pip install fire2a-lib

4. Visit fire2a-lib documentation, example:

from fire2a.downstream_protection_value import digraph_from_messages
digraph = digraph_from_messages('messages01.csv')

Command line usage

1. Install QGIS

• Docker users check qgis container
• Linux developers could skip QGIS by apt install python3-gdal gdal-bin

2. Use python from the terminal

• Windows: Open OsGeo4W Shell app, python is available
• MacOS: Open terminal app, use this /Applications/QGIS.app/Contents/MacOS/bin/python (see creating an alias below)
• Linux: Do a system site packages aware python virtual environment python3 -m venv --system-site-packages qgis_venv

3. Install

python -m pip install fire2a-lib

4. Visit fire2a-lib documentation, example:

python -m fire2a.cell2fire -vvv --base-raster ../fuels.asc --authid EPSG:25831 --scar-sample Grids/Grids2/F
orestGrid03.csv --scar-poly propagation_scars.shp --burn-prob burn_probability.tif

Scripting tips

• Check standalone scripting for more info on initializing a headless QGIS environment
• Usage examples
• Microsoft users check this VSCode integration
• macOS users add a permanent alias, on the terminal app

echo "alias pythonq='/Applications/QGIS.app/Contents/MacOS/bin/python'" >> ~/.zshrc

Interactive

• debbuging:

breakpoint()
from IPython import embed
embed()

• sessions, with: IPython, qtconsole, jupyter-lab, or IPyConsole (QGIS plugin) compatible

# Interactive explore from IPython
In [1]: from fire2a.<press-tab>

# Select and Copy a whole module from line 1 up -but not included- to 'def main def main(argv=None):' line 
In [2]: %paste

# Choose your args 
In [3]: args = arg_parser.parse_args(['-vvv', '--base-raster', ...
# Skip:
    if argv is sys.argv:
        argv = sys.argv[1:]
    args = arg_parser(argv)

# Ready
