The document discusses the privacy and data protection issues related to the use of unmanned aerial systems (UAS) for earth observation. It notes that while geospatial data collected by UAS does not directly relate to individuals, powerful sensors could allow individuals to be identified if captured, which may implicate data protection law. The document also examines how quasi-stationary, high-altitude UAS conducting prolonged observation could raise some privacy concerns if individuals are visible. It outlines resources and guidance being developed to help drone operators and professionals address these legal issues through privacy by design and risk assessments.
