摘要
根据卫星遥感数据的分辨率、采集频次、获取方式等特点,将MODIS卫星遥感数据应用到渤海海冰遥感监测中。通过海冰在可见光和红外光波段的光谱存在特定差异的特性,对海冰发生面积进行提取。同时对渤海海冰进行了遥感监测,并完整地监测到海冰从发生到极盛再到消退的全过程。同时,在海冰发生最为严重的时段,对辽东湾海域进行了密集监测。研究结果表明,MODIS卫星遥感数据在海冰监测中有着及时、准确的优势。
According to the characteristics of resolution, collection frequency and the methods to obtain the remote sensing data, the MODIS satellite remote sensing data was applied to remote sensing of Bohai sea ice. With specific differences of sea ice in the visible and infrared spectral bands, the occurrence areas of Bohai sea ice were extracted. By the remote sensing of Bohai sea ice, its whole process was complete monitored from occurrence to the prime and then fadeaway. Research results showed that MODIS satel- lite remote sensing data appears promptness and accuracy in sea ice monitoring.
