摘要
在智慧城市建设中,移动平台已成为其中主要建设内容。跨平台移动终端是智慧城市中移动平台的重要实现,采用Xamarin跨平台的框架研究和实现了可应用于Android和iOS移动设备的移动终端。以应用于智慧城市建设的跨平台移动端为例,介绍了移动终端应用提出了可行的设计方案,同时阐述了在移动终端的实现中的采用的关键技术:空间定位技术、MMVC模式和移动端和服务器端数据交换技术。结合2019年版智慧城市技术大纲对移动终端要求,通过开发实例介绍了跨平台移动终端实现的用户登陆、地图服务、数据采集、移动定位、POI搜索等功能。跨平台移动终端不仅可以满足各种用户对GIS的功能需求,也能运行于当前主流移动操作系统,大幅度提高了开发效率,推广了地理信息服务的应用。
In the construction of smart city,mobile platform has became one of the main construction content.Cross-platform mobile terminals are an important implementation of mobile platforms in smart cities,using Xamarin cross-platform framework research and implementation of mobile devices that can be applied to Android and iOS mobile devices.Taking the cross-platform mobile terminal applied to the construction of smart city as an example,this paper introduces the feasible design scheme of mobile terminal application,and expounds the key technologies used in the realization of mobile terminal:spatial positioning technology,MMVC mode and mobile and server-side data exchange technology.Combined with the requirements of the 2019 smart city technology outline for mobile terminals,the user landing,map service,data acquisition,mobile positioning,POI search and other functions realized by cross-platform mobile terminals are introduced through development examples.Cross-platform mobile terminal can not only meet the functional needs of various users of GIS,but also run in the current mainstream mobile operating system,greatly improve the development efficiency,promote the application of geographic information services.
