Design And Realization Of GISVlog

The history of cartography dates back to antediluvian. It has been more than 4,500 years since the first map was made by the cartographer in Old Babylonia. And the first complete Geographical Information System (GIS) which is accepted by public was proposed by a Canadian in 1965 . Since 1995 researchers in China began to pay attention to GIS. Deep research on object-oriented data model, raster-to-vector translation, three dimensional data structure combining linear octonary tree and tetrahedron, three dimensional spatial analysis based on point-set topology, standard for the accuracy and quality of spatial data, hypergraph theory and "3S" integration techniques were done in theory. Industrial applications were widely implemented in the areas such as manufacture, disaster defending, layout, military affairs and so on. Due to the success of WebGIS, the functions of GIS spread though the World Wide Web (WWW) immediately in public.However, there is a common phenomena existing in the GIS field. Most of the time people except those technicians who need to use the professional software about GIS nearly refer to the map (both paper and electronic). Even for those researches, not the real map but the techniques of GIS are what they concern about. Nowadays, with the development of WWW, the population of people using internet increases dramatically and they depend on the internet more and more, therefore, make the techniques of WebGIS popular. But if people lose interest in the internet, as an attachment WebGIS will also become valueless because people will seldom use it. As all known the value of a technique depends on the number of users and the frequency of usage. If we can make GIS an important part of people's daily life, they will use it as much as possible. So the problem becomes how to keep people's enthusiasm for using GIS.In this paper a Geographical Information System Video Log (GISVlog) model is designed based on the techniques of GIS, integrated internet technology and web 2.0. First the history of GIS and constraint on its development are reviewed. In order to find the root of this constraint, the demand of the society is analyzed. According to this background, the GISVlog model is proposed and its importance is discussed. Second the architecture of the complete GISVlog model is designed and the function of each block is analyzed based on the characters of the techniques used in the GISVlog model. Then each function block and data block is built and the prototype of GISVlog is obtained. Finally the future of the new information medium - GISVlog is discussed.The content of this paper is organized as follows:Chapter 1 reviews the history of the development of GIS and brings out one constraint is that this application lacks of consumers. Then the problem becomes that if we can find an application of GIS that can make people use the map frequently.Chapter 2 proposes a GISVlog model. First it analyzes the root of the problem in Chapter 1 based on the constraint on the development of GIS. Second it discusses the demand of the society and seeks the solution of the problem. Then it presents the GISVlog model and analyze its possibility. Finally it analyzes the importance of GISVlog model.Chapter 3 analyzes the function of this model and designs its architecture. First choose the development and design mode and whole system design frame. Second analyze the function architecture. Finally analyze the function of each block.Chapter 4 designs and implements the prototype of the GISVlog model. First establishes the basic development environment and then designs and implements the details of each block. Finally obtains and displays the prototype of the GIDVlog model.Chapter 5 prospects the future of the GISVlog development.
