Discussion on the application and development of urban planning in mobile GIS

1 , overview

The urban construction process is speeding up, the urban planning management is becoming more and more heavy, the data of various sources produce various problems, which seriously affect the accuracy of urban planning, so we can make more scientific decision by mastering all aspects of urban planning information comprehensively and rationally. The rise of mobile has provided great convenience to the dynamic aspects of planning, all kinds of the deep development of wireless terminal, intelligent equipment, network communication and mobile GIS core technology, can provide planners and decision-makers with online offline, positioning real-time, status history and other aspects of the Analysis Services, so as to improve urban and rural planning efficiency.

2 , Mobile GIS Technology Selection

From the current situation of mobile device development, there are Apple, Samsung, domestic mobile phone products, tablets, from the operating system, Android, IOS, Winphone, Rim/blackberry BlackBerry, from the development language, there are object-c, JAVA, ActionScript, C#.net, with the rise of Web2.0, HTML5 has gradually developed into a mobile web trend.

Table 1 Comparison of mobile technology

Technical Route	Developing cross-platform	Master Development IDE	Advantages	Disadvantages
Object-c,swift New language	Mac, iOS only	Xcode	Performance, stability, interaction the most right is the election, feature-rich	Single platform, high development cost, long cycle, strict review, installation restrictions
java	windows, Mac, Linux, Android and BlackBerry platforms only	eclipse,myeclipse
C#.net\c++	Windows, Winphone only	Visual studio	Performance, stability, easy to develop, feature-rich	Single platform, high cost, development in a preliminary
As3-flex	Cross-platform support	Flashbuilder	Effective, cross-platform, easy to develop, save costs	The interaction effect is poor, the system is not open, the application is not many
html5+ back end Group mobile web	browser open, cross platform	multiple IDE	low cost, no plug-in, maximum support all, easy to develop learning, Easy to expand, real-time updates, future upstart	Use few cases, performance, stability to consider , technology needs to be qualitative, not widely popular
Native+web composition of hybrid hybrid applications (including HTML5)	Cross-platform, based on native native application extensions	Multi-IDE	Web applications that embed specific platforms primarily on iOS and Android primitives to compensate for a single form of inadequacy and to be the best combination at a certain level of demand	The application case has embedded web, but there is still no native application more

ESRI provides a variety of mobile support for the ArcGIS API for Ios,arcgis API for Android,arcgis APIs for Flex,arcgis APIs for Js,arcgis APIs for flat \winphone, etc. Application development can be done easily with basic support. However, according to the development needs of the project to establish which technology route to use, considering the project cost, cycle, functional requirements, target users, technology accumulation, talent strength and later operations and other aspects, to achieve a good user experience and extensibility.

3 , urban planning in mobile GIS application of the aspect operation

Mobile applications are generally available, valuable, efficient and attractive, for light-weight applications, lightweight media, should not be the kind of complex business function operations, but should be the core of small business execution, off-line acquisition and other aspects, involving the GIS part is also downloaded offline map offline implementation of a small number of functions.

Application 1: Multi-source multi-resolution map browsing

Through the online download of two-dimensional, three-dimensional, image and other tile data to mobile devices, complete the basic map function: zoom, zoom, navigation, measurement and so on.

Application 2(one of the core): Planning query (place name query, project query, parcel query, approval query, planning results query, etc.) based on the input criteria for a simple search query and display results, can be positioned to display.

Application 3: Thematic layer management, overlay

To manage the data downloaded online, the Basemap overlay planning results and thematic data are displayed on an as-needed basis.

Application 4(core bis): Planning Office

Online/offline and office software seamless integration, support daily Office transaction processing, not limited by time and place, a machine in hand, do all.

Application 5(Core III): Planning for Data collection (map)

offline, such as planning for parcel editing increase, property updates, and so on, online will automatically synchronize data to the server, complete the integration of data Management Update synchronization operations.

Application 6: Planning Business information push

Support mobile push Some of the latest information content, similar push effect.

Application 7: Historical Data comparison (spatio-temporal evolution)

The multi-source image data is compared and the difference decision is made.

Application 8: auxiliary function

Map error correction, shortest best path search, draw marks and so on.
