Abstract
The development of Small Unmanned Aerial Vehicles (SUAV) with the capability to carry hi-resolution consumer grade digital stills and video cameras, coupled with the rise of powerful desktop ‘photogrammetrical’ software packages has seen a revolution in aerial data capture (2D/3D) in both the research and commercial survey and Geomatics communities over the last few years.
Access to this ‘lower cost’ aerial data acquisition method coupled with advances in personal computing power is enabling researchers to collect, process, model and analyse topographical features that traditionally have been the reserve of Remote Sensing Technologies managed by larger Corporations and/or Government Organisations.
This paper will demonstrate the use of such technologies as a means of generating high resolution topographical surface models of recently exposed sub-glacial bed-form features at resolutions similar to that of established aerial LiDAR data acquisition techniques, albeit at a smaller geographical scale.
SUAV imagery collected as part of a 2014 field season to Tarfala research station and nearby Isfallglaciären in Swedish Lapland, (FLUTE MORPHOMETRY FROM PHOTOGRAMMETRY [FluMP] - INTERACT 2014) has been processed using desktop based Structure from Motion (SfM) techniques to generate high resolution Digital Surface Models (DSM) detailing exposed Flute morphology at the glacier foreland, enabling metric analysis in a GIS. We hope to demonstrate that this technique is a powerful Remote Sensing tool in the field of mapping and analysing Geomorphological structures.
