    GPU Based Graph Bundling Using Geographic Reference Information



    A common source of challenges in geographic visualisation systems is the growing amount of available data. Datasets containing different information need to be merged and analysed under a common context. For some purposes these datasets can interact intelligently and append additional information to a scientific visualisation. In this research proposal, we show how we are planning to optimize the process of bundling graphs to traffic networks and present a general method to solve this challenge.
