Remote Sensing for Environmental Scientists

Module summary

Module code: ENVI1176
Level: 6
Credits: 15
School: Engineering and Science
Department: Natural Resources Institute
Module Coordinator(s): Meredith Williams



The aim of this module is to introduce the students to the concepts and principles behind remote sensing and photogrammetry, and their applications to environmental science challenges. The module will explore the characteristics of remotely sensed data, their collection, processing, and display. This module also aims to introduce basic image processing techniques through ‘hands-on’ experience. During this module, students are introduced to a wide variety of remote sensing platforms and sensors. Students get extensive practical experience in dealing with a varied range of remotely sensed environmental data using ERDAS Imagine and ESRI ArcGIS. The module also aims to briefly explore the theory and techniques of analogue and digital photogrammetry.

Learning outcomes

On successful completion of this module a student will be able to:
1. Understand the key concepts and terms used in the fields of remote sensing and photogrammetry.
2. Critically evaluate the role and limitations of a broad range of remotely sensed imagery types in a variety of environmental contexts.
3. Understand the principles of photogrammetry and critically review its use in environmental survey problems.
4. Determine the optimum combination of statistically valid field calibration and validation activities, image pre-processing, and remote sensing analysis, for an environmental issue.
