Monitoring Trends in Burn Severity Fire Occurrence Locations (Feature Layer)

The Monitoring Trends in Burn Severity MTBS project assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (includes wildfire, wildland fire use, and prescribed fire) 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 point of the location of all currently inventoried and mappable 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. The point location represents the geographic centroid for the _BURN_AREA_BOUNDARY polygon(s) associated with each fire. MetadataThis record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

《监测烧伤严重程度趋势》MTBS项目对从Landsat主题测绘器档案开始至当前，美国本土、阿拉斯加、夏威夷和波多黎各的所有大型野地火灾（包括野火、野地火灾利用和计划性火灾）的频率、范围和强度（大小和严重程度）进行评估。所有在西部的美国报告面积超过1,000英亩，在东部的美国报告面积超过500英亩的火灾，均在所有所有权下进行绘制。MTBS生成一系列地理空间和表格数据，以便在多种空间、时间和主题尺度上进行分析，旨在满足对空间和时间上火灾影响一致性数据的需求。此地图层为所有目前记录并可绘制的火灾的位置矢量点，这些火灾发生在1984年日历年至今的MTBS发布中，涉及美国本土、阿拉斯加、夏威夷和波多黎各。请访问https://mtbs.gov/announcements以确定当前版本。未绘制到该地图清单中的火灾，是由于缺乏合适的卫星图像或从可用图像中无法辨认的火灾。点位表示与每个火灾相关联的_BURN_AREA_BOUNDARY多边形的地理质心。元数据：此记录来自向https://data.gov目录提供数据的USDA企业数据目录。此记录的数据包括以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService、OGC WMS、CSV、Shapefile、GeoJSON。欲获取完整信息，请访问https://data.gov。
