Abstract：
Rapid development and applications of unmanned aerial vehicles (UAVs) provide promising solutions to and new opportunities for environmental monitoring. Owing to their flexibility in flight scheduling, high spatial resolution, and costs-effectiveness, UAVs have become a popular tool for monitoring dynamic environmental processes, such as emergence and outbreak of harmful algae blooms (HABs). The HABs outbreak, often linked with anthropogenic eutrophication, has become a serious environmental health problem that threats our communities. Existing studies show that UAV-based HABs monitoring is a cost-effective means of assisting environmental managers in developing precautionary warning system and coping strategies. This article summarized the state-of-the-art of using UAVs and lightweight onboard multispectral sensors for HABs monitoring from the perspective of quantitative remote sensing. It culminates in a discussion of challenges and opportunities for future research and applications on drone-based HABs monitoring.
摘要：
无人机的快速发展和应用为环境监测提供了有希望的解决方案和新的机会。由于他们在飞行时间安排上的灵活性，高空间分辨率,和成本效益，无人机已经成为监测动态环境过程的流行工具，例如有害藻类繁殖（HABs）的出现和爆发。HAB爆发，通常与人为富营养化有关，已经成为威胁我们社区的严重环境健康问题。现有研究表明，基于无人机的HAB监测是一种经济有效的手段，可以帮助环境管理人员制定预防预警系统和应对策略。本文从定量遥感的角度总结了使用无人机和轻型机载多光谱传感器进行HAB监测的最新技术。最终讨论了基于无人机的HAB监测的未来研究和应用的挑战和机遇。
