This project aims to map burnt areas within NSW in a way that is useful for bushwalkers. When vegetation is burnt in a bushfire, it generally removes scrub and makes the area easier to travel through for a few years. Knowing where these recently burnt areas are can then assist in route planning for bushwalks.
An example can be found through the link below, where a geojson file has been imported into an online map. Burnt Areas Map - 20181113
