本文介绍了一个在线教学工具，介绍了学生的基本概念，遥感及其在水文应用。该学习单元的对象是没有（或很少）遥感经验但具有环境科学、水文学、统计学和编程方面的一些基本背景的大三/大四本科生或大三研究生。这一电子学习环境提供了关于遥感基本原理的背景内容，但也整合了一套现有的在线工具，用于卫星观测的可视化和分析。具体而言，向学生介绍了可用于监测和分析水文循环变化的各种卫星产品和技术。在完成该模块后，学生能够将遥感数据可视化（包括时间序列和空间图），检测时间趋势，解释卫星图像，并评估遥感产品中的错误和不确定性。学生们有机会检查他们的理解，因为他们通过模块的进展，并使用专业人士和科学家在实践中常用的遥感观测来解决复杂的现实问题。该学习工具在HydroLearn中实施，HydroLearn是一个开源在线平台，供教师查找和分享学习模块，并合作开发水文学和水资源教学资源。
This article presents an online teaching tool that introduces students to basic concepts of remote sensing and its applications in hydrology. The learning module is intended for junior/senior undergraduate students or junior graduate students with no (or little) prior experience in remote sensing, but with some basic background of environmental science, hydrology, statistics, and programming. This e-learning environment offers background content on the fundamentals of remote sensing, but also integrates a set of existing online tools for visualization and analysis of satellite observations. Specifically, students are introduced to a variety of satellite products and techniques that can be used to monitor and analyze changes in the hydrological cycle. At completion of the module, students are able to visualize remote sensing data (both in terms of time series and spatial maps), detect temporal trends, interpret satellite images, and assess errors and uncertainties in a remote sensing product. Students are given the opportunity to check their understanding as they progress through the module and also tackle complex real-life problems using remote sensing observations that professionals and scientists commonly use in practice. The learning tool is implemented in HydroLearn, an open-source, online platform for instructors to find and share learning modules and collaborate on developing teaching resources in hydrology and water resources.
