ABSTRACT:
In this paper, we presented a web application created using the NASA Web WorldWind framework. The application is capable of visualizing n-dimensional data using a Voxel model. In this case study, we handled social media data and Call Detailed Records (CDR ) of telecommunication networks. These were retrieved from the « BigData Challenge 2015 » of Telecom Italia.
We focus ed on the visualization process for a suitable way to show th is geo-data in a 3D environment, incorporating more than three dimensions.
This engenders an interactive way to browse the data in their real context and understand them quickly. Users will be able to handle several varieties of data, import their dataset using a particular data structure, and then mash them up in the WebWorld Wind virtual globe.
A broad range of public use this tool for diverse purposes is possible, without much experience in the field, thanks to the intuitive user – interface of this web app
