Historical Fire Extent and Severity Mapping (FESM) - Sturt 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 Sturt National Park 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.

火灾严重性是衡量火灾造成的生物量损失的指标。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合作，基于卫星影像开发了一套依托机器学习框架的半自动化制图方法，用于绘制火灾范围与过火严重性分布图。

该方法采用标准化分级体系，以实现不同区域火灾事件间的横向对比。火灾范围与严重性制图（Fire Extent and Severity Mapping，简称FESM）的严重性分级涵盖：未过火、低严重性（林下植被被烧毁，林冠未受灼烧）、中度严重性（林冠部分灼伤）、高严重性（林冠完全灼伤、部分林冠被焚毁）、极端严重性（林冠完全焚毁）。

本次数据集提供了1989/90至2015/16财年斯塔特国家公园（Sturt National Park）区域的历史过火严重性制图数据，该数据基于陆地卫星（Landsat）影像生成。2016/17财年至当前火灾年度，该区域数据纳入全州范围的FESM数据集，其影像来源为哨兵2号（Sentinel 2）卫星影像。
