Whitehead and Hugenholtz (2014) provided a detailed account of the prospects of UAV in environmental remote sensing. As the present paper is exclusively dedicated to glaciological research, we compared
the number of UAV-based glaciological publications to all environmental remote sensing publications (Whitehead & Hugenholtz, 2014) (Fig. 1). For a fair comparison,we adopted the same characterisation scheme for relevant articles as that used inWhitehead and Hugenholtz (2014). For keyword searches, we used Scopus andWeb of Science and excluded book chapters or conference papers from this compilation. From Fig.
