Abstract

The Special Natural Reserve of Malpaís de Güímar is a recent volcanic enclave, colonized by typical vegetation formations of the basal floor of the south of Tenerife (Canary Islands, Spain). The beekeeping that is currently carried out in this area requires a reliable mapping of the flora that conforms it. This work analyses the potential of hyperspectral images of 10 cm, captured from a UAV in June 2018, to make a preliminary thematic map of the species of interest. The study focuses on a reduced area of 6 ha, in order to assess the feasibility of the methodology and then apply it to the whole of the protected area. The results of applying a traditional algorithm to two sets of spectral bands obtained from the original 150, between 400 and 1000 nm, were compared. The first, result of a study of spectral separability and the second from the Principal Components Analysis. The best-classified species was the Cardon with an omission error of 17.70% and a commission error of 12.26%.
