The invention relates to a surveying and mapping method based on hyperspectral remote sensing of an unmanned aerial vehicle. Comprising the following steps: firstly, designing and integrating a lightweight and high-efficiency hyperspectral sensor module and an unmanned aerial vehicle carrying system, and ensuring that a sensor can stably operate on various unmanned aerial vehicles; developing a real-time data processing algorithm, and integrating a machine learning technology to improve the processing speed and analysis accuracy of data collected from the hyperspectral sensor; then establishing a ground verification system, designing a ground sampling and verification scheme, and ensuring the consistency and accuracy of the data by comparing and analyzing the ground data and the hyperspectral data collected by the unmanned aerial vehicle; the collected hyperspectral data is combined with a geographic information system (GIS) technology to construct a three-dimensional map, and a visual platform is developed,
