GEOGG140 Image Processing and GIS
CORE GEOGG140 - Image Processing and GIS
Term 1 (2013)
Staff: Dr J G Liu & Dr P J Mason
The aim of this course is to introduce transferable knowledge, techniques and computing skills to handle with remote sensed imagery data for image visualization, thematic information enhancement and extraction and geographic information manipulation using digital image processing and GIS. The course also introduces the knowledge of radar remote sensing including radar interferometry.
The module will introduce essential knowledge and techniques of image processing and geographic information system (GIS) for remotely sensed images in order to enhance, classify, extract and analyse thematic information for various remote sensing applications. The details of the content of the course are shown in the teaching outline below.
8 lectures (12 hr) and 8 practicals (12 hr)
- Map composition and data preparation
- Coordinates, projections & datums
- Image georectification & warping
- Surfaces, visualisation and terrain analysis
- Geostatistics & interpolation
- Map algebra concepts
- Spatial analysis in geosciences
- Multi-criteria evaluation
Image Processing and Radar Sensing:
5 lectures (15 hr)
- Point operations: contrast enhancement and algebraic operations
- Filtering and neighbourhood processing
- RGB-HIS transformation and principle component analysis
- Principle of radar (SAR) remote sensing and earth science applications
- Radar interferometry and applications for terrain change analysis
3 Practicals (9 hr)
- Basic operation of ER Mapper and contrast enhancement
- Algebraic operation and filtering
- RGB-IHS transform and principle component analysis
3 hour unseen exam, 100% of the assessment, takes place in the first week of term two.
The module will be delivered through a series of lectures and matching hands-on computer-based practical sessions.
At the end of the module, students should:
- Understand the principles and mathematical background of image processing and GIS.
- Be able to use and understand image processing and GIS software packages and to apply these to various applications of remote sensing.
- Understanding the principles of radar remote sensing.
