MTBS Wildfire Occurrence

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 for the period of 1984 through 2018. 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 2018 for the continental United States, Alaska, Hawaii and Puerto Rico. The point location represents the geographic centroid for the _BURN_AREA_BOUNDARY polygon(s) associated with each fire.

背景概述

MTBS Wildfire Occurrence数据集记录了1984年至2018年美国本土、阿拉斯加、夏威夷和波多黎各所有面积大于特定阈值（西部1,000英亩、东部500英亩）的大型野火发生情况，以矢量点形式表示火灾的地理质心，并提供地理空间和表格数据，用于分析火灾的频率、范围和严重性，支持多尺度的时空研究。
