Multisensor data fusion demand in Earth observations is constantly increasing thanks to technological advances and the willingness to explore the Earth in a multidisciplinary way. Recently hyperspectral imaging has become a promising tool for Earth monitoring purposes but has also emerged as suitable for fusion with other remote sensors for various applications. This dissertation examines different types of multisensor data fusion, such as feature-level and application-level fusion, where each application is based on hyperspectral imaging at the airborne scale. In feature-level data fusion, hyperspectral imaging is combined with LiDAR (Light Detection and Ranging) to analyze urban environments, mainly focusing on urban land cover classification and implementing deep learning algorithms. In contrast, application-level data fusion presents the integration of hyperspectral imaging with magnetic data for material characterization of geologic complexes in remote and harsh environments, such as Greenland.
