Research And Construction Of Data Visualization System Based On Spatial Dimension

At present,with the in-depth development of Internet+in various industries,the scale of the data is ever expanding.With the development of GPS on mobile platforms and the rise of location-based services in the Internet industry,the data with the spatial dimension is plentifully growing.In the era of big data,a variety of high-capacity,multi-dimensional complex data filled people's eyeballs.In order to more efficiently interpret data and explore the potential values of data,the data visualization technology came into being.Compared with the traditional data types,the data with the attribute of the spatial dimension is more complex,diverse and spatial,and has great research potentials in the field of data visualization.The visualization of data with the spatial dimension can better help people interpret data,uncover the associations between data information and data.At the same time,the data display will give users a more friendly view.Responding the need to visualize the geographic data with the spatial dimension,this paper first analyzes the development trend of data visualization on the internet,and investigate on and learn about the key technology of developing Web visualization system based on B/S model.On the basis of this,a complete visualization system architecture and data processing procedures are developed by combining the related knowledge of geographic information.The system design is divided into two modules:the front end and the back end,which respectively is the server side of the data scheduling module and the browser side of the visual display module.The data scheduling module mainly includes:source data preprocessing module,data processing and calculation module,data storage module and so on,while the visual display module includes front-end data visualization display,data transmission module and so on.In addition to the traditional visualization model,the system also use the map model and the earth model to provide the solving ideas for the visualization of the data with the spatial dimension.Through the design and development of the system,it has realized the complete process from data to visualization,which meets the needs of visualization.
