Monitoring Trends in Burn Severity (MTBS) Hawaii

The Monitoring Trends in Burn Severity (MTBS) Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data about fire effects through space and time. This map layer is a thematic raster image of MTBS burn severity classes for all inventoried fires occurring in Hawaii during calendar year 2022. Fires omitted from this mapped inventory are those where suitable satellite imagery was not available, or fires were not discernable from available imagery.火灾严重程度监测趋势（Monitoring Trends in Burn Severity，MTBS）项目负责评估1984年至今美国本土（conterminous United States，CONUS）、阿拉斯加、夏威夷及波多黎各境内所有大型野外火灾（野火与计划烧除火）的发生频率、波及范围与强度（规模及严重程度）。其中，美国西部上报过火面积超1000英亩、东部超500英亩的所有火灾，均会在全土地权属范围内开展制图工作。MTBS可生成一系列地理空间与表格数据，用于多空间、时间及主题尺度的分析，旨在满足各类需获取跨时空火灾影响一致性数据的信息需求。本次提供的地图图层为2022日历年夏威夷境内所有已清查火灾的MTBS火灾严重程度等级专题栅格影像。未纳入本次制图清查的火灾，为无可用适配卫星影像，或无法通过现有影像识别的火灾。
