EASTWeb Framework – A Plug-in Framework for Constructing Geospatial Health Applications
Abstract: Disease maps and forecasts developed using satellite remote sensing data can inform the decisions of public health officials and improve disease control and epidemic response. However, potential users in the health science fields face a variety of barriers to accessing earth science datasets, including a lack of remote sensing expertise, limited time and resources to acquire the needed skills, and limited access to necessary software.
The open-source, client-based software Epidemiological Applications of Spatial Technologies (EASTWeb) was developed to automate the retrieval, processing, and storage of satellite remote sensing data for public health research and applications. In order to improve the system, there is a need to expand the types of earth observation data that EASTWeb can process so that it can be used more broadly in a wide range of geospatial health applications. The EASTWeb framework introduces novel plugins and a plugin factory to provide users a convenient way to customize the framework into applications for different earth science data streams.
This presentation talks about the detailed design of the plugin framework and its four sub-frameworks, and a scheduler that controls the working threads. As a case study, an application with six plugins for six different earth observation products is constructed to demonstrate how the EASTWeb framework can be easily extended to support different data streams. It will also provide examples of environmental indicators that have been generated using EASTWeb to support forecasting of West Nile virus outbreaks in the United States and malaria epidemics in the Ethiopian highlands.
