Visualization of geospatial data based on flash technology and its application in socio-economic data

Social and economic data are almost paid greatest attention by the country leaders and used to sense the situation of a country. The manner of visualization and data analysis to social and economic data will greatly affects the knowledge detection and information acquisition, so designing a good analysis system would be very necessary. This paper tries to use flash technology to design an online visualization and data analysis system to the social and economic data. By comparisons with the traditional web GIS systems, the system designed by the paper has great priorities in following three aspects: (1) Accelerating the online data analysis speed by changing the common work flow. (2) Enhancing the system interactivity by integrating and associating the spatial map, attribute data and statistics chart. (3) Creating a distribute map for any selected element and generating a time series animation dynamically. The result shows that using flash technology can achieve difficult functions that the traditional GIS software can´t realize.
