Abstract: UAV hyperspectral technology is an important research direction in the field of remote sensing, which can obtain spatial and spectral information of geological features quickly and efficiently. With the advantages of flexibility and low cost, it has received wide attention from experts in recent years. This paper summarizes the characteristics and current status of UAV hyperspectral imager, describes the composition and research status of UAV hyperspectral remote sensing system, and focuses on the latest application progress in the investigation on natural resources, such as mineral mapping, water quality monitoring, forest resources survey and soil quality evaluation. In terms of the current problems of UAV hyperspectral remote sensing technology, three predictions are proposed, i.e. system miniaturization, multi-band integration and multi-source data fusion. It also points out that UAV hyperspectral remote sensing technology will have a wider application prospect in the technology system of natural resources integrated survey and monitoring.
