摘要

摘要: 智能终端和移动互联网的快速发展使得移动空间信息服务成为数字城市和数字地球的重要内容，而各种基于定位导航的嵌入式地理信息系统(geographic information system，GIS)也逐步成为这类信息服务的主要方式.分析了现代移动空间信息服务的特征，采用层次式模块化的方法，介绍了基于GIS的可移植抽象层、多元数据存储模型、电子地图显示引擎和高性能应用服务引擎等关键模块的设计，设计了可移植的嵌入式GIS平台，为通用的移动空间信息服务移动端的应用开发提供了一个切实可行的方案.

Abstract: Due to rapid development of intelligent terminals and Internet, the mobile spatial information services becomes an important part of Digital City and Digital Earth, and the kinds of embedded geographic information system (GIS) based on positioning and navigation become the main form of the services. This paper analyzes the characteristics of modern spatial information services, with hierarchical modular design method. The modules, such as portable GIS-based abstraction layer, multiple data storage model, electronic map display engine and high-performance applications service engine is introduced. A portable embedded GIS platform is designed, which provides a practical solution for popular application development of mobile spatial information service.
