September 2017 - October 2013

Awarded PhD in Geomatics, School of Engineering, Newcastle University, UK, “Morphology-based landslide monitoring system with a UAV”.

Aim: To investigate the potential of a consumer grade UAV system to provide accurate time series of 3D landslide information in the absence of physically established control points. A morphological-based strategy was developed applying surface morphological attributes in combination with the scale-invariant feature transform (SIFT) algorithm to generate pseudo control information and co-register multi-epoch UAV datasets for landslide monitoring.

Supervisors: Prof J.Mills, Prof P.Moore, Dr P.E.Miller (The James Hutton Institute) and J.E.Chambers (British Geological Survey).

Funding: This research was jointly funded by a Natural Environment Research Council (NERC) BGS BUFI award (S241) and an Engineering and Physical Sciences Research Council (EPSRC) DTA award (EP/L504828/1).

September 2013 - August 2011
