A System Architecture of 3D Virtual Earth Based on Mobile Platform

Abstract

The invention provides system architecture of a three-dimensional virtual globe based on a mobile terminal. The system architecture takes cross-platform design into full account, the defect in the prior art that system architecture of a three-dimensional virtual globe cannot run on mobile equipment of multiple operating systems is avoided, the cross-platform design satisfies the characteristics of being small in load, high in self-adaption and perceiving the context, the quick platform characteristic is achieved, the system architecture achieves high-cohesion design, achieves the purpose that a single module is only responsible for achieving one task and achieves low-coupling design, few and simple interfaces among modules are arranged, so that each module can complete a specified function task, the multi-thread system architecture is adopted, systems are both mutually independent and precisely matched with each other during running, all threads can be both mutually independent and related to each other, resource characteristics of the mobile terminal are given play to to the largest extent, and system experience of a user can also be strengthened.

Description

technical field [0001] The invention relates to a system framework of a three-dimensional virtual globe, in particular to a system framework of a three-dimensional virtual globe based on a mobile platform, and belongs to the technical field of mobile three-dimensional virtual globe framework. Background technique [0002] With the development of network information technology, the three-dimensional virtual earth geographic information service model based on traditional PCs cannot meet the public's needs for fast and rapid response to geographic information services. Services for the public increasingly require that the three-dimensional virtual earth system can provide Anytime, anywhere, on-demand, multi-source information service model based on geographic information. [0003] At the same time, with the rapid development of wireless networks and mobile terminals, the mobile 3D geographic information service system based on Mobile GIS (Mobile Geographic Information System, m...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a system architecture of a 3D virtual globe based on a mobile platform. The system architecture fully considers the cross-platform design, which makes up for the fact that the system architecture design of the 3D virtual globe in the prior art cannot be used in multiple operating systems. The defects of the normal operation of mobile devices, the cross-platform design meets the characteristics of small load, strong self-adaptation, and context awareness, and can adapt to the two mainstream system platforms of IOS and Android while using the least system resources and automatically perceive the context of the system , realizing fast platform features, system architecture realizes high cohesion design, system modules are composed of highly correlated codes, realizes that a single module is only responsible for one task realization, system architecture realizes low coupling design, modules and modules The interfaces between them are few and simple, so that each module can complete specific functional tasks. Using a multi-threaded system architecture, the different threads of the system are independent and closely coordinated with each other during runtime, so that each thread can run independently and be able to Interconnected, maximizing the characteristics of mobile device hardware resources, and enhancing the user's system experience
