UAV Imagery and 3D Modelling of Earthwork Heritage Sites in the Peak District National Park
The preservation of earthwork heritage sites is of utmost importance as they are fragile and therefore vulnerable to external threats such as agriculture , urban encroachment , mining , tourism and climate change . However , the United Nations Educational , Scientific and Cultural Organisation ( UNESCO ) made heritage a focal point in the Convention Concerning the Protection of the World Cultural and Natural Heritage adopted in 1972 . Additionally , the United Nations Sustainable Development Goals 8 and 11 in 2015 outlined the need for promotion of sustainable tourism and preservation of heritage . Through utilising aerial imagery gathered using Unmanned Aerial Vehicles – drones – Structure from Motion ( SfM ) and GIS software , high resolution orthomosaic images , Digital Elevation Models ( DEMs ), and 3D models have been created of four earthwork monuments in the Peak District National Park . The level of resolution achieved from the collected aerial imagery ranges from 2 to 4 cm , higher than what is available as downloadable datasets from the Ordnance Survey . The intent of this presentation is to demonstrate the preliminary results of the modelling and inform on what more can be done with the data , such as visualisations of erosion and volumetric calculations , which can aid in heritage management , preservation and documentation .
