Abstract

A method of providing prompt information includes obtaining sensitive area information and marking a sensitive area on a navigation map according to the sensitive area information. The sensitive area affects a flight of an unmanned aerial vehicle (UAV). The method further includes obtaining position information of the UAV, determining a positional relationship between the UAV and the sensitive area according to the sensitive area information and the position information of the UAV, and generating the prompt information according to the positional relationship.
