Course description and aims

Obtaining an accurate picture of large-scale natural disasters in metropolitan areas can be difficult. Although quick damage estimation systems such as strong ground motion monitoring and/or flow monitoring by utilities may be available, a time lag between the initial damage estimation and the actual damage assessment is unavoidable. Observations of damaged areas by helicopters, airplanes, and satellites provide information to fill in initial quick damage estimates with actual damage assessments that are timely, cover a large area, and have high accuracy, respectively. In particular, remote sensing by satellites can provide observations of a wide area with a single image, and it may be possible to use this technology to improve the accuracy of large-scale damage estimates.
This course focuses on the change (damage) detection algorithms by remotely sensed images. Particularly, the conventional and advanced image processing of optical and radar remote sensing are introduced to students who are interested in disaster management fields. The fundamental knowledge on the image processing of optical remote sensing, radar data acquisition and imaging, and their characteristics are learned. The principles of interferometric SAR (InSAR) and its application for measuring crustal movement due to natural disasters are also presented. Because sensors and observation systems are constantly advancing, the newest methodology in the field is also discussed. Students will have good understanding and basic skills of remote sensing in disaster management through this course.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand the remote sensing based damage detection methodologies and explain the examples of their application.
2) Explain the principles of radar remote sensing and synthetic aperture radar (SAR), and their characteristics.
3) Understand the interferometric process of SAR phase information and its application for disaster monitoring.

Keywords

optical image, synthetic aperture radar (SAR), Interferometric SAR, image processing, damage detection

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

At the beginning of each class, key points of the previous class are reviewed. In the class, students are given exercise problems related to the lecture given that day to solve. To prepare for the class, students should read and check what topics will be covered from the materials uploaded on web site in advance. Required learning should be completed outside the classroom for understanding and review new technologies.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
