Fire Extent and Severity Mapping (FESM) 2016/17

Fire severity is a metric of the loss of biomass caused by fire. In collaboration with the NSW Rural Fire Service, DPE Remote Sensing & Regulatory Mapping team has developed a semi-automated approach to mapping fire extent and severity through a machine learning framework based on sentinel 2 and Landsat satellite imagery. Fire Extent and Severity Mapping for the 2016/17 fire year is based on Landsat 8 imagery. Fire Extent and Severity Mapping from the 2017/18 fire year onward is based on Sentinel 2 imagery. The statewide severity map has standardised classes to allow comparison of different fires across the landscape. The FESM severity classes include: unburnt, low severity (burnt understory, unburnt canopy), moderate severity (partial canopy scorch), high severity (complete canopy scorch, partial canopy consumption), extreme (full canopy consumption).\r\n\r\nThis dataset represents the 2016/17 fire year, including wildfires >100ha with fire start date between July 2016 and June 2017.\r\n

火灾严重性（Fire Severity）是衡量火灾引发的生物量损失的量化指标。新南威尔士州乡村消防局（NSW Rural Fire Service）与DPE遥感与监管制图团队携手合作，基于哨兵2号（Sentinel 2）与陆地卫星（Landsat）系列卫星影像，通过机器学习框架开发了一套半自动化的火灾范围与严重性制图方法。2016/17火灾季的火灾范围与严重性制图产品基于陆地卫星8号（Landsat 8）影像制作；2017/18火灾季及此后的同类制图产品则以哨兵2号影像为数据源。该全州范围的严重性地图采用统一标准化分级体系，可用于对比不同区域的各类火灾。火灾范围与严重性制图（Fire Extent and Severity Mapping，简称FESM）的严重性分级包含以下类别：未燃烧、低严重性（林下层燃烧、冠层未受灼烧）、中严重性（冠层部分灼伤）、高严重性（冠层完全灼伤、冠层部分焚毁）、极端严重性（冠层完全焚毁）。

本数据集对应2016/17火灾季，涵盖起火时间介于2016年7月至2017年6月之间、面积大于100公顷的野火。
