国产卫星数据在国土资源监管中的探讨 ——以广西壮族自治区为例

A discussion on domestic satellite data in land and resources supervision：Taking Guangxi Zhuang Autonomous Region as example

近年来,国产卫星数据资源日益丰富,采用卫星遥感数据对国土资源利用情况进行动态监测,是一条行之有效的技术路线.通过总结近4a来国产卫星数据在广西国土资源监管中的实际应用案例,介绍了相关的数据处理技术方法,对存在的有关数据源、数据质量、坐标系及空间分辨率等问题进行了探讨,提出了根据管理工作的实际需要,采用国产卫星与无人机数据相互补充的实用方法,可满足国土资源宏观和微观管理的需求,达到预期的效果.

In recent years, domestic satellite data resources have become increasingly rich, and the application of satellite remote sensing data to the dynamic monitoring of land use is an effective technical route. In this paper, the authors summarized the practical application cases of domestic satellite data in Guangxi land and resources supervision in the past four years, described the related data processing technology, discussed the existing data sources, data quality, coordinate system and resolution, and proposed the practical methods of the complementing of each other for the domestic satellite and unmanned aerial vehicle data according to the actual needs of the management work, which can meet the requirements of macro and micro management of land resources so as to achieve the desired effect.
