Exploring the World virtually

Software Components for Data Visualisation

The Digital Earth Viewer is a component-wise scalable web-based framework for simultaneous visualisation of multiple heterogenous data sources. It helps contextualise mixed observation and simulation data in time and space by creating a virtual 4D environment for the user to explore.

The software was conceived as a hybrid application split into a server back-end and a client front-end. The server back-end can be hosted remotely for access through the internet or locally for offline usage. The client front-end can be accessed using any popular web browser without the need to install any other software components.

Currently, general-purpose-sources are implemented for the netCDF, ESRI ASCII Grid, and CSV file formats, as well as facilities to load data from WMS or Maptile-servers or to interact with SQLite databases. Specialised sources have been built to read and display Acoustic Doppler Current Profiler (ADCP) data, GPX tracks, and further application-specific formats. As the Digital Earth Viewer is under constant development, new sources and functionalities are being added all the time!
