Historical Fire Extent and Severity Mapping (FESM) - Royal-Heathcote Region

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 satellite imagery. \r\n\r\nThe method uses 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\nHere we provide historical severity mapping for the Royal-Heathcote region from 1989/90 to 2015/16, which is based on Landsat satellite imagery. From 2016/17 to the current fire year, this region is covered in the statewide FESM data, which is based on Sentinel 2 satellite imagery.

火灾严重性（Fire severity）是衡量火灾导致生物量损失的量化指标。新南威尔士州农村消防局（NSW Rural Fire Service）与DPE遥感与监管制图团队合作，基于卫星影像搭建机器学习框架，开发了一套半自动化的火灾范围与严重性制图方法。

该方法采用标准化等级体系，以实现不同区域各类火灾的横向对比。FESM火灾严重性等级包括：未燃烧、低严重性（林下植被燃烧，冠层未受波及）、中等严重性（冠层部分焦枯）、高严重性（冠层完全焦枯、部分冠层焚毁）、极端严重性（冠层完全焚毁）。

本数据集提供了1989/90至2015/16年间罗亚尔-希思科特（Royal-Heathcote）地区的历史火灾严重性制图数据，该数据基于陆地卫星（Landsat）影像生成。2016/17火灾年度至今，该区域的火灾数据已纳入全州范围的FESM数据集，该数据集基于哨兵2号（Sentinel 2）卫星影像制作。
