SPA404 Remote Sensing Algorithms (8)
Abstract|
In this subject, students learn important mathematical concepts and algorithms commonly used in processing of multispectral remote sensed imagery. This includes understanding the sources and characteristics of remote sensed data and the geometric and radiometric corrections to remote sensed imagery. On completion, students will have the ability to select and use an appropriate image processing technique to enhance and classify land cover classes using multispectral image data. |

Learning OutcomesUpon successful completion of this subject, students should:
- be able to describe the sources and characteristics of remote sensed data;
- be able to make the appropriate radiometric and geometric changes to correct remote sensed imagery and to view geometry distortions;
- be able to implement the specialised mathematical and statistical skills needed to undertake appropriate image processing techniques used in remote sensing;
- be able to select and analyse the most appropriate image processing techniques to enhance and classify land cover classes using multispectral image data.
