摘要
空间数据是地理信息系统研究的核心内容之一。在关于PostGIS的研究中,现有的空间数据管理方案多是基于矢量数据,对栅格数据存储方式的探讨较少。以PostgreSQL数据库与PostGIS空间拓展为基础,对空间数据表进行结构设计,完成了PostgreSQL空间数据操作类库的方案设计。用户可以使用本方案管理使用空间数据库,实现矢量数据与栅格数据的一体化管理;同时,本方案设计了每个模块中具体的类、接口、结构和方法等,并将其实现为第三方类库,可供开发人员的组织与调用。
Spatial data is one of the core contents of GIS research.In the research on PostGIS,the existing spatial data management schemes are mostly based on vector data,and there is less discussion on the storage mode of grid data.Based on PostgreSQL database and PostGIS spatial expansion,we designed the structure of spatial data table and completed the scheme design of PostgreSQL spatial data operation class library.Users can use this scheme to manage and use spatial database to realize the integrated management of vector data and grid data.At the same time,the specific classes,interfaces,structures and methods in each module were designed and implemented as a third-party class library for developers to organize and call.
