Distributed Voyager (dVoy)

Developed and hosted by the

Center for Air Pollution Impact and Trend Analysis (CAPITA) at

Washington University in St. Louis

 

 

 

Welcome to distributed Voyager (dVoy), a spatio-temporal environmental data tool based on Web standards. dVoy has three major components: data access, navigation and display which interact following the model-view-controller (MVC) paradigm. The data access (model) layer offers a homogeneous, read-only access mechanism to a changing collection of heterogeneous, autonomous and distributed information sources.  The Voyager data access uses a global multidimensional schema consisting of spatial, temporal, parameter and other dimensions common to environmental data.  This schema enables the development and implementation of web-based tools for exploring and analyzing environmental data.

 

dVoy is currently in its prototype stage but is available for preview and preliminary testing:
