Historical Fire Extent and Severity Mapping (FESM) - Kosciuszko 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 Kosciuszko 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.

火灾烈度是衡量火灾造成生物质损失的量化指标。新南威尔士州规划与环境部（DPE）遥感与监管制图团队与新南威尔士州农村消防局（NSW Rural Fire Service）合作，开发了一套基于卫星影像的机器学习框架，以半自动化方式绘制火灾范围与烈度分布图。

该方法采用标准化分级体系，以支持不同区域火灾情况的横向对比。FESM烈度分级包含以下类别：未燃烧、低烈度（林下植被被焚烧，冠层未受影响）、中烈度（冠层部分灼伤）、高烈度（冠层完全灼伤，部分冠层可燃物被消耗）、极端烈度（冠层完全被消耗）。

本数据集提供了1989/90年度至2015/16年度科修斯科（Kosciuszko）地区的历史火灾烈度分布图，该数据集基于陆地卫星（Landsat）影像构建。2016/17年度至今，该区域的火灾烈度数据已纳入全州范围的FESM数据集，其数据源为哨兵2号（Sentinel 2）卫星影像。
