🗺️ WazeTT

Research project for calculating off-trail isochrones

Exemples of use cases :

• ⛑️ Helping rescuers estimating the possible positions of an injured person in the nature
• 👮 Helping police locating fugitives
• 🔥 Helping firefighters estimating the propagation of the fire in a forest
• 🌊 Helping engineers sizing hydraulic structures by estimating flood propagation
• ⛰️ Helping hikers finding their way in the mountain
• 💣 Helping the army finding its way in their intervention missions given dynamic events (e.g. collapse of a bridge, presence of terrorists, etc.)
• ... and many more !

Note : this solution is made to be executable locally, i.e. without any internet connection

⛰️ Input data

The solution is compatible with cartographic datasets obtained from GeoServices Open API:

• Altitude datasets can be found as .asc files (raster):
  • BD alti (25m resolution)
  • RGE alti (1m or 5m resolution)
• Field datasets can be found as .shp files (vectorial):
  • BD Topo (metric precision)
  • BD Carto (decametric precision)

🔽 Installation (Linux)

Open a terminal, download the repository :

git clone https://github.com/will-afs/WazeTT

Go into the directory :

cd WazeTT/

Create a Python virtual environment :

python3 -m venv .venv

Activate the virtual environment :

source .venv/bin/activate

Install the project dependencies :

pip install -r requirements.txt

⚙️ Configuration

The project can be configured through the project_config.toml file

▶️ Usage

The source code is accessible through the /src folder

The different notebooks give a general overview of the solution

⚗️ Main steps of the program

1. Importing altitudes as a 2D table

2. Importing fields polygons (vegetation) included in altitude data bounding box

3. Making fields 2D table from fields polygons (green = vegetation, yellow = grass)

4. Calculating off-trail isochrone from altitudes and fields datasets
