Monitoring Trends in Burn Severity Burned Area Boundaries (Feature Layer)

The Monitoring Trends in Burn Severity (MTBS) Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (including wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico from the beginning of the Landsat Thematic Mapper archive to the present. 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 vector polygon shapefile of the location of all currently inventoried fires occurring between calendar year 1984 and the current MTBS release for CONUS, Alaska, Hawaii and Puerto Rico. Please visit https://mtbs.gov/announcements to determine the current release. Fires omitted from this mapped inventory are those where suitable satellite imagery was not available or fires were not discernable from available imagery.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

《监测火灾严重程度趋势》（MTBS）项目评估了从Landsat主题测绘仪档案起始至今，美国本土、阿拉斯加、夏威夷和波多黎各等地所有大型野地火灾（包括野火和计划性火灾）的频次、范围和强度（大小及严重程度）。所有报告面积超过1,000英亩的西部美国火灾和超过500英亩的东部美国火灾均映射于所有权属之上。MTBS项目产出了一系列地理空间和表格数据，旨在分析多种空间、时间和主题尺度，以满足对火灾影响时空一致性数据的多重信息需求。此图层为1984年至当前MTBS发布期间，美国本土、阿拉斯加、夏威夷和波多黎各等地所有已记录火灾位置的矢量多边形形状文件。请访问https://mtbs.gov/announcements以确定当前版本。未包含在此映射目录中的火灾是指那些缺乏适宜卫星图像或无法从现有图像中辨识的火灾。此记录来源于为https://data.gov目录提供数据的美国农业部企业数据目录。此记录的数据资源包括以下内容：ISO-19139元数据、ArcGIS中心数据集、ArcGIS地理服务、OGC WMS、CSV、Shapefile、GeoJSON、https://doi.org/10.5066/P9IED7RZ、https://www.mtbs.gov/。如需完整信息，请访问https://data.gov。
