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.

构建水文科学中卫星遥感应用的在线学习模块

本文介绍了一种在线教学工具，向学生介绍了遥感的基本概念及其在水文学中的应用。该学习模块适用于没有（或很少有）遥感经验但具有环境科学，水文学，统计学和程序设计的一些基本背景的初中/高级本科生或初中研究生。这种电子学习环境提供了有关遥感基础知识的背景知识，而且还集成了一套用于可视化和分析卫星观测的现有在线工具。具体来说，向学生介绍了可用于监视和分析水文循环变化的各种卫星产品和技术。完成模块后，学生能够可视化遥感数据（包括时间序列和空间图），检测时间趋势，解释卫星图像以及评估遥感产品中的误差和不确定性。使学生有机会检查自己在模块中的理解，并通过专业人员和科学家通常在实践中使用的遥感观测来解决复杂的现实生活中的问题。该学习工具在HydroLearn中实现，HydroLearn是一个开放源代码的在线平台，教师可以通过该平台查找和共享学习模块，并协作开发水文学和水资源方面的教学资源。使学生有机会检查自己在模块中的理解，并通过专业人员和科学家通常在实践中使用的遥感观测来解决复杂的现实生活中的问题。该学习工具在HydroLearn中实现，HydroLearn是一个开放源代码的在线平台，教师可以通过该平台查找和共享学习模块，并协作开发水文学和水资源方面的教学资源。使学生有机会检查自己在模块中的理解，并通过专业人员和科学家通常在实践中使用的遥感观测来解决复杂的现实生活中的问题。该学习工具在HydroLearn中实现，HydroLearn是一个开放源代码的在线平台，教师可以通过该平台查找和共享学习模块，并协作开发水文学和水资源方面的教学资源。
