td-kernel-dmvw 0.1.0

This project provides an algorithm for calculating gas distribution maps.

TD Kernel DM+V/W

The algorithm implements the theoretical research of the following papers:

Besides the root algorithm (KernelDM), it contains the proposed extensions:

• time dependency (TD)
• variance (V)
• wind dependency (W)

Thanks to Achim Lilienthal, Patrick Neumann and Victor Hernandez for providing Matlab implementations for the extensions V and W.

Requirements

• Python 3
• pipenv

Run demo

Run the following code to generate the different maps. The mean map, variance map and confidence map are being plotted.

pipenv install --dev
pipenv run python simple_example.py
