Research SNS And Map Mashup Technology

The way of people's live has been changed by the popularity of the Internet. Since the twenty-first century there are many new internet technologies generated with the development of Web2.0. The applications of these new technologies make the development of the network faster and make more people participating in the network application. Web1.0is centered as content while Web2.0is centered as user. So, Web2.0is supported by more users, which also generated a lot of new applications, such as blog, Wiki, Network Abstract and microblog. Mashup mainly refers to a variety of internet resources aggregation, and ultimately the formation of new service, which is architected by API/content providers, the mashup site and the client browser. As a new technology of internet, mashup has applied in many Internet products. Mashup fully embodies the Web2.0's feature:openness, user-centric and lightweight development. At present, there are many applications based mashup technology, and maps mashup is one of the most common applications. Map mashup mainly refers to the aggregation map, map-based visualization and spatial analysis functions in the web application.SNS (Social Networking Sites) is also the product of development of Web2.0. Through SNS, people set up social circle similar to real life. This mode of internet communication of human-centered becomes the inevitable choice of the people social networking. Social networks provide users with a lot of space information, including the user's location information, the location of matters discussed, published microblogging location information, etc. Although some of the social networking site provides a map application, but the function is relatively weak. Combining with location information in SNS and maps, you can produce some new applications. And the geographical characteristics of the social network user behavior can be analyzed by aggregating the mashup results.In this paper, I research social networking and map Mashup technology and implementation methods, use the online map service in ArcGIS Online resources and published by ArcGIS Server (including national administrative map, as well as the Shanghai Administrative Map), aggregate map data and sina webo data using ArcGIS JavaScript API and sina weibo open platform API, develop a platform aggregated SNS and map service. The functions of this platform are landing map positioning based on the geographical location of registration, distribution of the location of the user's friends, weibo topic geographical features and analysis, and showing weibo information on the map through map design. Through this platform, the information obtained can make full use of location information and be more intuitive to show up on the map.
