摘要
为了解决由于不同数据模型中同一空间实体的编码不惟一而导致数据共享困难以及标识的静态性和无空间位置等问题,本文提出了基于全球剖分格网的空间信息全球惟一编码模型(GeoID),并设计了该编码模型的系统架构,试图实现全球连续的、多层次空间信息的惟一标识。通过对遥感影像中的空间实体进行了编码探讨,结果表明空间信息全球惟一编码模型将大大加快信息的查询与检索速度。
To solve data sharing problem caused by different codes of the same geospatial object and their identifications having no level and geospatial information,it puts forward a new geospatial information global unique code,GeoID,based on global subdivision grid(GSG) and designs the architecture to express continuous and multi-scale geospatial information.At last,it takes an example of encoding objects in a remote sensing image.The result showes that GeoID on global geospatial information may accelerate the speed of data query and research in the massive data storage.
