| 摘 要： | 高精度海量影像数据是天地图、数字城市等公共服务平台的基础数据源之一。巨大的数据量使得传统影像数据加工方法的效率大大降低,这也成为制约公共服务平台数据生产效率的瓶颈之一。本文基于ArcGIS10版本推出的Mosaic Dataset模型,实现了海量高精度影像数据的高效处理,从海量数据管理、数据预处理、投影变换、去黑边、填补空洞等方面,详细叙述了该模型在海量影像数据处理方面的应用。本研究期望为相关数据加工与生产提供借鉴。

| Abstract: | Mass Image data with high resolution is one of the foundation geographical datasets.Large data quantity of image rapidly decreases the processing efficiency based on traditional image process method.A new method is introduced in this paper based on mosaic dataset model which improved in ArcGIS 10.Within this method,mass image data management,data pre-processing,projection transformation,invalid area removal and nodata area filled are improved.Experiments show that the processing efficiency based on this new method could rapidly increase and storage space that required by image processing is saved. |
