当前遥感领域各个国家不断加大投入，星载数据资源日益丰富。伴随大数据等前沿技术的发展与深入应用，遥感在宏观层面上已经得到了较为充分应用，对于全球变化以及地球系统科学研究而言是一个重要的数据源。我国已经成为国际上的遥感大国，高分专项的实施标志着民用航天遥感进入亚米级时代。但是，由于空间分辨率与重访周期之间的矛盾，高分辨率卫星数据的可获得性尚不能满足一些不断增长的应用需求。国内遥感应用尚停留在宏观层面，主导是政府部门，用户也是政府各级部门。遥感在满足大量微观和大众具体应用层面尚没有落地。无人机遥感的出现与快速发展，为促进遥感应用落地起了很好的助推作用，无人机遥感在区域信息精细化上具有高科学价值，具有高空间分辨率、高频次、高性价比等特点，可以与卫星遥感能力形成互补，缓解了高空间分辨率和时间分辨率的矛盾，在低成本的基础上实现了空间和时间的辩证统一。当前无人机遥感的发展尚处于初级阶段，但呈现出一些极具特色的应用前景，尤其是无人机“遥感+”应用发展迅猛。同时，发展过程中也还有诸多政策、技术与方法方面的问题。本文在总结无人机未来发展趋势的同时，对无人机遥感的发展，从政策、技术与应用等层面提出了建议。
At present
every country in the field of remote sensing is increasing investment
and satellite data resources are increasingly rich. With the development and in-depth application of big data and other cutting-edge technologies
remote sensing has been fully applied at the macro level
and is an important data source for global change and earth system science research. China has become a big remote sensing country in the world. The implementation of high-resolution project marks the civil space remote sensing entering the sub-meter era. However
due to the contradiction between spatial resolution and revisit period
the availability of high-resolution satellite data can not meet some growing application needs. The application of remote sensing in China is still at the macro level
dominated by government departments and users at all levels of government. Remote sensing has not yet been implemented to meet a large number of micro and public specific applications. The emergence and rapid development of UAV remote sensing has played a very good role in promoting the application of remote sensing. UAV remote sensing has high scientific value in the refinement of regional information
with the characteristics of high spatial resolution
high frequency and high cost performance. It can complement the satellite remote sensing ability
alleviate the contradiction between high spatial resolution and time resolution
and on the basis of low cost It realizes the dialectical unity of space and time. At present
the development of UAV remote sensing is still in the primary stage
but it presents some unique application prospects
especially the rapid development of UAV " remote sensing +” application. At the same time
there are many problems in policy
technology and method in the process of development. At the same time of summarizing the future development trend of UAV
this paper puts forward some suggestions on the development of UAV remote sensing from the aspects of policy
technology and application.
