随着空间信息处理需求的不断扩大，对空间信息数据和时间的分辨率要求也越来越高。现有的空间信息细分、编码、存储等理论已不能适应新的需求。本文提出了一种新的基于经纬度的细分模型，并讨论了一种新的域编码方法。在该编码系统中，每个细分patch都可以被唯一有效地识别，并且还可以将位置与patch联系起来。同时确定后续的空间信息处理，如定位、索引、查询等。域管理系统是一个多层次、分层、分布式的编码数据库。在patch细分和域编码的基础上，根据计算机网络协议，提出了全局空间信息的集成编码方法GeoID。集成编码包括patch的级别、空间信息的时间、存储地址、存储方式等。上述解决方案为海量空间数据处理提供了新的理论和方法，具有一定的实用性，值得推广。
As the constantly expanding demand for spatial information processing,the requirement of the resolution of spatial information data and time become increasingly demanding.The previons theory of spatial information subdivision,encoding,storage and so on cannot qualify the new requirements.In this paper,a new subdivision model based on latitude and longitude has been put forward and a new domain encoding has also discussed.In this encoding system,each subdivision patch can be identified uniquely and efficiently and can also relate the position with the patch.And the follow-up spatial information processing such as location,index and query can be decided at the same time.The domain management system is a multi-level,layered and distributed database for encoding.On the base of patch subdivision and domain encoding,the integration encoding of global spatial information named GeoID is proposed according to computer network protocol.The integration encoding includes the level of patch,the time of spatial information,address of storage,mode of storage and so on.The above solutions provide the new theory and method for mass spatial data processing,and it is practical and should be promoted.
