The goal of this project is to develop standards and methods to collect and analyze data to generate a better understanding of topography, fuel and weather around wildland fires to support fire management and firefighting decisions. Drones, supplemented by satellite imagery, will be used to collect visual and multispectral vegetation (fuel) data. Machine learning methods will be used to infer vegetation characteristics of interest, including tree species, size, shape, connectivity, density, surface fuel composition, crown fuel characteristics and ladder fuel distributions. Using this data, better fire behavior predictions will be made which will allow for better management of wildland fires in Canada. Specifically, the project explores four applications of drones for improved wildland fire planning and operational decision making (1) use collected data around the perimeter of a community at risk to wildland fires to assess closeness and density of trees and vegetation, which is used for fire risk assessments, (2) fly drones to structures ahead of wildland fires to perform field exposure assessments and make structure triage decisions during active fires, (3) improve prediction of fire spread and direction, and (4) use collected data to inform improved decision making on deployment of suppression activities such as airtankers, waterbombers, helicopters and ground crews.

该项目的目标是制定收集和分析数据的标准和方法，以便更好地了解野火周围的地形、燃料和天气，以支持火灾管理和消防决策。无人机，辅以卫星图像，将用于收集视觉和多光谱植被（燃料）数据。机器学习方法将用于推断感兴趣的植被特征，包括树种、大小、形状、连通性、密度、表面燃料组成、树冠燃料特征和阶梯燃料分布。利用这些数据，可以做出更好的火灾行为预测，从而更好地管理加拿大的野火。具体而言，该项目探索了无人机在改善野火规划和操作决策方面的四种应用(1)使用在野火风险社区周围收集的数据来评估树木和植被的接近度和密度，用于火灾风险评估；(2)在野火发生前将无人机飞到建筑物上进行现场暴露评估，并在火灾活跃时做出结构分类决策。(3)改进对火势蔓延和方向的预测；(4)利用收集到的数据为部署灭火活动（如空中加油机、水轰炸机、直升机和地勤人员）提供改进的决策信息。
