遥感影像变化监测及网格化策略应用

Remote Sensing Image Change Monitoring and Grid Strategy Application

为了解决遥感变化监测过程中的多期数据严密度和数据冗余问题,提升变化监测工作效率,提出了一种网格化策略。在自然资源领域,遥感影像变化监测可实现对疑似违法行为的“早发现”,为“早制止、早处置”自然资源管理和保护提供支撑提出了一种网格化策略,在执行变化监测任务前对卫星数据进行分析处理,划分地理网格并入库,根据一系列数据筛选原则确定所需影像对,而无需对影像数据进行镶嵌生产,可提升变化监测生产效率。

In order to solve the problems of multi-period data rigor and data redundancy in the process of remote sensing change monitoring,and improve the efficiency of change monitoring,in the natural resources field,remote sensing image change monitoring can realize“early detec-tion”of suspected illegal acts,and provide support for“early stop and early disposal”of natural resource management and protection.In this pa-per,we proposed a grid strategy,which analyzed and processed satellite data before performing change monitoring tasks,divided geographical grids into the database,and determined the required image pairs according to a series of data screening principles.There is no need for mosaic production of image data,which can improve the production efficiency of change monitoring.
