Wildfire Suppression Difficulty Index 97th Percentile 2024 (Image Service)

Wildfire Suppression Difficulty Index (SDI) 97th Percentile is a rating of relative difficulty in performing fire control work under regionally appropriate fuel moisture and 20 mph uphill winds (@ 20 ft).SDI factors in topography, fuels, expected fire behavior under prevailing conditions, fireline production rates in various fuel types with and without heavy equipment, and access via roads, trails, or cross-country travel. SDI does not account for standing snags or other overhead hazards to firefighters, so it is not a firefighter hazard map. It is only showing in relative terms where it is harder or easier to perform suppression work.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

野火抑制难度指数（SDI）97百分位数是对在适宜区域燃料含水量和每小时20英里上坡风速（20英尺高度）条件下执行火控作业相对难度的评级。SDI考虑了地形、燃料、在现有条件下预期的火行为、各种燃料类型中是否使用重型设备的火线生产率，以及通过道路、小径或越野旅行的方式可达性。SDI不计入对消防员构成威胁的倒木或其他空中障碍物，因此它不是消防员危险地图。它仅以相对术语显示在何处进行抑制工作更为困难或容易。本记录源自美国农业部企业数据目录，该目录输入至https://data.gov目录。本记录的数据包括以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService。欲获取完整信息，请访问https://data.gov。
