I am facilitating a PhD research project by the School of Geography and Environmental Studies funded by a local Council in southern Tasmania. The residential area is known for large-scale, slow-moving landslides but the extent and rate of recession of adjacent coastal cliffs is unclear.
The initial aim of the photogrammetry research is to get high definition imagery of a short section of cliff line using small unmanned aircraft, in particular where parts of the cliff are vegetated and parts unvegetated, to see if the method can effectively eliminate vegetation effects and so detect small scale changes to the whole cliff surface irrespective of vegetation cover. If successful, the approach could be extended further along the several kilometres of cliffs in the area, and further afield.
The first photogrammetry run will be in the next month or two.
