Degrees and qualifications

Doctor of Philosophy (PhD) / Master of Philosophy (MPhil)

The Department is well recognised as a regional centre of excellence in geomatics research. It topped the worldwide ranking according to a Thompson Reuters report. The department has a state-of-the-art Research Centre for Geo-Information Science and Technology that enables staff and students to carry out research with the latest tools.

The PhD and MPhil programmes aim to provide rigorous training to students who aspire to become researchers and/or scholars capable of producing independent and original research, and of producing research findings that are relevant and significant to their chosen fields of specialisation.

The MPhil study requires candidates to undertake critical study of a chosen area while the PhD study demands candidates to accomplish a study which makes a significant contribution to knowledge deserving of publication.
