Google Map Service Support Public Geographic Information Service System Of Design And Realization

Geographical Information Service is generated by the rapid development of GIS and Internet technology. It can provide real-time, rich location information which related services to the Internet users. Public Geographical Information Service is the product of social development of Geographical Information Service, which is for the public, in order to provoid a variety of Geographical Information Service to the public based on professional, flexible and varied ways. At present, many departments have tried to apply Public Geographical Information Service into the practice and have achieved positive results. However, the GIS data is the important issues of GIS.The issues of the difficult of data processing and it can't be applied flexibly are wides- pread in the Public Geographical Information Service. It has also become the public Geographical Information Service's problem to be solved.The issue is concerned to solve the above problem.As the problem exists in the Public Geographic Information Service System, the issue designed and implemented Public Geographic Information Service System of Ganzhou under the Google Maps service support, which by the ues of its free API , open functionality, ease of use, and high-resolution images.The designment and implementation of Public Geographic Information Service System which supported by the Google Maps service in this issue, exerts object-orien- ted analysis and design techniques, and completed the entire process of analysis and design. In the progress of analysis and design, it completed the requirements analysis, architecture design, detailed design, coding and run debug of the system. The system has good operation effect, it can realize the basic functions of GIS maps and meet the basic demands; and it can realize the integration of GIS system and Urban Geographic Information such as schools,hotels, attractions, routes and so on, it provides a variety of flexible queries, navigation tools, and it can show the information which the public needs.The importantce of the issue research include as follows:(1)The Analysis of Google API technology, it mainly researches the classes of Google Maps API and Google Earht COM API, And also the designation of the 3D models by Google SketchUp.(2)The analysis and application of the grammatical structure of KML files, And using KML / KMZ files to display three-dimensional display.(3)The Internet development technology of ASP.NET and C#, it adopts the B\S architecture structure to design the system.(4)Use the integration of Ajax,Google API exploit technology and web exploit technology to design and display Public Geographic Information Service System.
