Kurzfassung
We present a collection of digital elevation models and orthorectified mosaics of the 100,000 m^2 wave-cut pavement in the Bristol Channel near Lilstock, UK. The pavement is a world-class outcrop that perfectly exposes a very large fracture network in several thin limestone layers. The dataset of high-resolution mosaics of aerial photographs and digital elevation models of the complete outcrop was acquired by unmanned aerial vehicle during two field-days, using different survey altitudes optimized to resolve all fractures. The resolution of the orthorectified mosaics varies from < 1 cm/pix to 5 cm/pix, depending on the altitude the original photographs were taken from. All fractures visible at outcrop scale are resolved in the models except for the overview created using photographs taken from 100 m altitude.
