摘　　要：随着遥感技术的迅速发展,影像数据量也越来越庞大,而遥感影像是地理国情监测的重要组成部分。使用传统的影像处理方法如坐标转换、图像镶嵌等,会输出多次中间结果,耗时长,资源占用多并产生巨大的数据冗余,已无法满足地理国情监测底图快速制作的需求。本文探索了一种基于Mosaic Dataset的影像快速处理方法,该方法通过建立影像索引,从而无须输出中间结果,效率较高,能够满足影像快速应用需求,具有实用性。With the rapid development of remote sensing technology , the image data is getting larger and larger and image data is an important part of national geographical condition monitoring .General image processing methods such as coordinate conversion , image mosaic, etc., output some intermediate results with more time and resource consuming , and will generate huge data redundancy . Those methods have been unable to meet the needs of existing rapid images application .This paper explores a new rapid processing method based on image Mosaic Dataset .The method does not output the intermediate results , and with more efficiency by creating an image index .It is able to meet the demands for rapid image application with practicality .
