自然资源高频次卫星遥感监测----国土变更调查监测产品

利用高频次卫星遥感监测产品，探索日常变更调查机制，创新变更调查的思路和模式。通过按月度的日常变更调查监测全地类图斑，调查人员根据实际情况及时进行变更核查和举证，分解年底集中调查举证的任务压力，确保变更调查地类的准确性和可靠度；实现“多监合一、一监多用”；针对违法用地实现“早发现、早制止”。
在常态化监测的基础上，增加全要素变化监测，按需利用高分辨率遥感影像，增加监测频次，满足国土变更调查要求。

Leveraging high-frequency satellite remote sensing monitoring products, this work explores the daily land change survey mechanism and innovates the ideas and models of change surveys. By monitoring all land-type patches via monthly routine change surveys, surveyors can conduct timely change verification and proof submission based on on-site actual conditions, thereby alleviating the task pressure of centralized investigation and proof submission at the end of the year, and ensuring the accuracy and reliability of land types in change surveys. This achieves the goal of "integrating multiple monitoring functions and realizing one monitoring for multiple purposes", and enables "early detection and early cessation" for illegal land use.
On the basis of regular monitoring, full-factor change monitoring is added, and high-resolution remote sensing images are utilized as needed to increase monitoring frequency, so as to meet the requirements of national land change surveys.
