Remote Sensing Applications in Hydrology


George Mason University & UC Berkeley

Problem Statement

Remote Sensing Applications in Hydrology

Module Overview

This module 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 will be 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 satellite-based Earth observations that professionals and scientists commonly use in practice.

Topics Covered

Fundamentals of Satellite Remote Sensing for Hydrology

The Temporal Dimension of Satellite Data

The Spatial Dimension of Satellite Data

Uncertainty and Error Assessment

Prerequisites

Some background in statistics is required.

Learning Objectives

Upon completion of this course students will be able to display, map, process and develop analytical workflows to identify remote sensing products from which they can extract information for a broad range of hydrological applications. This will be accomplished through activities within each section.
