基于多源遥感影像的省级天地图更新技术研究

Research on Provincial MapWorld Update Technology Based on Multi-source Remote Sensing Images

分析了影像电子地图的应用需求、影像数据情况以及目前影像电子地图更新存在的问题,提出了利用ArcGIS镶嵌数据集处理影像数据,更新影像电子地图的方法流程和利用FME搭建批处理模块进行结合图数据处理的方法,解决了影像电子地图更新过程中多源影像显示优先顺序问题和结合图信息查询问题。并将此方法应用于福建省月度影像电子地图更新,结果表明方法具有可行性,能为相关工作提供参考。

In this paper,we analyzed the image electronic map application requirements,the image data and the problems existing in the current image electronic map update,put forward the method of processing image data and updating image electronic map by using ArcGIS mosaic data set and the method of combining image data processing by using FME to build batch processing module,and solved the priority order of multi-source image display and the query of image information in the process of updating electronic image map.We used this method into the monthly image electronic map update of Fujian Province.The result shows that the method is feasible.
