Landsat-based Burn Area Mapping in Victoria, Australia

[pinkychow1010]

What is the objective of the proposed tutorial?
This tutorial is built in the context of 2019–20 Australian massive bushfire events. It aims to demonstrate users how to utilize open satellite imagery such as Landsat time series to map burnt areas from wildfire events. It covers steps such as data preprocessing (masking, mosaicking), computing fire indices (dNBR), thresholding, as well as creating visually pleasing simplified polygons for export to create maps.

What is the scope of the proposed tutorial?
Wildfire, Forest, Disaster Risk, Natural Hazard, Australia
