Considerations for the effective use of UAS-mounted multispectral sensors for archaeological
0Nicholas Crabb, Brighton University
The advent of low-cost UAS-mounted sensors has led to a proliferation in the use of multispectral imagery in archaeological projects. However, there are significant complexities surrounding the effective collection and processing of this data that require consideration to ensure its effective application. Specifically, the capability of UAS-derived multispectral imagery is heavily dependent upon the resolving characteristics of each sensor, as well as the atmospheric and ground conditions at the time of survey (e.g. land cover type, seasonality and the scale and nature of features being surveyed). This paper will provide an overview of these fundamental considerations and detail factors to maximise the potential detection and definition of archaeological resources. It will also provide case studies from a range of UK-based environments including dryland, wetland, and upland settings, demonstrating that contemporary UAS multispectral technology can be highly advantageous when used appropriately, but will only provide limited information when used in sub-optimal conditions.
