The 3D Map In Campus Development And Research Based On Android Platform

With the development of GIS industry, to create a three-dimensional map of the left a lot of space for the geographic information system developers, three-dimensional electronic map is the real world according to a certain proportion of China "to the computer, to the performance of a virtual geographic model in the virtual model, the user can query information through the simulation map that path navigation and other functions, convenient for people to travel and live.With the development of society, mobile phone has become an essential communication tool. Application of the GIS software development on the mobile phone is imperative. Through the study of relevant literature, I have understood the production of the basic model using 3D GIS and 3D modeling and Realization of the campus, to make the campus three-dimensional, the freshmen know a lot of information about the school in advance before registration, including school’s 3D building, the surrounding buildings and the freshman’s vehicle navigation map. In the later stage, in necessary circumstances new map and vehicle shuttle fire escape route would be added. Expanse school students, make the school digital. Through the 3D virtual simulation map expression, we will make the seamless integration of university campus in the basic geographic information, construction, road sign of streets and parks, square and other information, provide auxiliary support for the campus business management decision analysis.The research of this article is the campus three dimensional navigation system, mainly including location, acquisition the surrounding information, the line inquiry planning. According to the characteristics of the Android system, we have analyzed the system’s creation and development, system creation etc.. This paper will design and implementation of three dimensional campus navigation based on the Android system, have strict vulnerability testing, to ensure that the future use with convenient, safety.The research of this article is the campus 3D navigation system, mainly including location, access to information, the line around the query plan. According to the features of Android system, analyzes the system creation and development, system construction. In this paper, the design and implementation of three dimensional campus navigation based on Android system, strict testing to ensure that future vulnerabilities, convenient use, safety.This system is an innovation both in the field of mobile phone and in the field of 3D GIS APP, the combination of the two will make the system exceed the same product, through rigorous testing, the system is suitable for the Android version 2.2 or later, its function and performance meet the basic requirements of design.But the disadvantage is that due to the development of a large amount of information, it is difficult to put all the buildings or auxiliary models all show, if the latter business profit model is to increase its function, let the students do the questionnaire survey, according to the needs of students to add the 3D campus is more comprehensive, more complete, more in line with the campus life of APP.
