Description :
This paper outlines an experiment to collect high spatial resolution stereo-imagery for the photogrammetric generation of DEMs as input to geomorphological process-based studies. The AA. used a kite platform as it remains comparatively inexpensive, is extremely portable and can operate in a variety of environments. The research outputs are used to test the effectiveness of the methodology for providing low cost, high resolution data. The combination of kite and digital camera is more generally termed kite aerial photography (KAP). The accuracy of data derived by digital photogrammetry and imagery acquired using a kite based non-metric camera is assessed by 3 experiments : one on smooth terrain, one on tor terrain and one on a glaciofluvial esker. The results demonstrate that the method can extract a high number of sampling points at high accuracy, provided that there is suitable image texture across the site.
