SURV513 Resource Mapping and Image Processing

Digital image pre-processing and processing, including advanced processing techniques. Field data collection, image classification, and image enhancement. Students will produce a resource map and critically evaluate its accuracy based upon literature searches and field checks.

The increasing number of imaging sensors and platforms offer new exiting capabilities to observe and characterise our environment. Dealing with imagery requires a specific set of skills that are addressed in this paper. This paper also provides an opportunity to gain practical experience with various types of imagery and to complete of a comprehensive research project involving the use of images.

Paper Structure
Generally based in the context of remote sensing, this paper is aimed at providing an extended knowledge of image processing techniques used for the mapping of earth resources. It includes classic methods of pre-processing (e.g. gap-filling, calibration, geometric and radiometric correction), image enhancement (e.g. radiometric, spatial, multispectral enhancement, principal component analysis) and image classification (unsupervised and supervised), as well as advanced processing techniques (e.g. multispectral image fusion, spectral unmixing, fuzzy and object-orientated classification). The methodology for fieldwork, sampling, ground-truthing and accuracy assessment of the final resource maps is addressed to provide students with sufficient knowledge towards the completion of deliverables with a high-quality standard.

Image enhancement and manipulation techniques will be applied and analysed by the student to produce a resource map and critically evaluate its accuracy based upon a literature review and personal experiences.
Teaching Arrangements
The theoretical content of this paper is addressed over two hours of lectures weekly.

Practical experience is gained during 11 practical sessions in a well-equipped computer laboratory, whereby students will be asked to carry out a research-led project that relies on imagery and image processing techniques. This is a major component of the paper.
