As the growing worldwide population becomes more mobile and urbanized, the risks that infectious diseases epidemic and their associated threats may reach global proportions are constantly increasing.

To effectively limit the social and economic damage caused by infectious diseases, the public health communities need to be in the position to anticipate the spatial and temporal evolution of epidemics and evaluate the potential impact of available containment and prevention strategies.

The global epidemic and mobility model, GLEAM, combines real-world data on populations and human mobility with elaborate stochastic models of disease transmission to deliver analytic and forecasting power to address the challenges faced in developing intervention strategies that minimize the impact of potentially devastating epidemics.

GLEAMviz simulator version 7 is out!

A new version of the GLEAMviz simulator has been released today: version 7.0 features a major rewriting of all the data handling components, together with some additional functionalities.

The output format for the results generated by the computational engine and managed by the client has been changed to a standard format, the Hierarchical Data Format version 5 (HDF5), developed by the NCSA; this change brings various advantages, in terms of scalability and extension of the output data, performances, and usability. Along with this modification we performed a significant architectural refactoring of all the data manager modules, adjourning the data retrieval process (which is now much faster) and setting the basis for future improvements and extensions in handling the simulations’ output.

The new software application is not compatible with the old custom data format, so we developed a simple conversion tool to allow users adjourn their existing simulations to the new format, and then open them in the Client version 7 for visualizing and analyzing. The conversion tool is distributed together with the GLEAMviz client and is called GLEAMconverter; its usage is straightforward: you just need to select one or more simulations (up to version 6.9) and an output directory.

The Visualization Dashboard with the X3D Globe widget.

The newly released Client also introduces a new visualization widget, the X3D Globe, which shows the incidence (new transitions) at the country level by means of 3D choropleth shapes on the Earth globe; the coloring range and other visualization options can be specified by the user.

Finally, version 7.0 also includes various improvements and bug-fixes both client-side and server-side: we do our best to continuously upgrade the GLEAMVIZ simulator!
