智慧遥感制图（iMap）

封面图片为清华大学宫鹏研究组在世界首次大范围实现长时间序列的无缝数据立方体及其应用过程示意图。图中左半球部分展示了太阳同步卫星轨道拍 摄的影像随时间积累所构成不同数量的原始影像堆叠，中间为经过无缝数据立方体构建技术形成的逐日无缝数据立方体，右半球部分为地表覆盖制图分 类应用。这种无缝数据立方体在定量遥感信息提取、图像分类及变化监测等方面能够得到广泛应用。相关研究进展，详见《遥感学报》2021 年第 1 期 第 126—147 页“21 世纪逐日无缝数据立方体构建方法及逐年逐季节土地覆盖和土地利用动态制图—中国智慧遥感制图 iMap（China）1.0”和第 2 期第 527—529 页“智慧遥感制图（iMap）”。

Intelligent mapping with remote sensing (iMap)

The cover image illustrates the process of constructing the world's first long time series large area daily seamless data cube realized by the research group led by Peng Gong at Tsinghua University. The sphere image contains three components: Left, the different number of raw image stack collected from sun-synchronous orbit satellites; Middle, the daily seamless data cube constructed with a series of integrated image processing, calibration, restoration techniques; Right, the land cover classification results. The seamless data cube can be easily used in such applications as quantitative information extraction, change detection and image classification.
