The GEON Integrated Data Viewer (IDV) is a fully interactive, true 3D and 4D tool to display and explore any data located on the Earth, inside the Earth, or above the Earth's surface. It is excellent for use in atmospheric sciences, solid earth sciences, and oceanography, if your data is point observations, 2D or 3D grids, vector data, imagery mapped on the Earth, and most any data mapped in or on the Earth.
The IDV has interactive, true 3D displays with full time animation where needed, and it also is a powerful tool for "cyberinfrastructure," "data interoperability," "simultaneous displays of differing data types," or "mashups."
- General Purpose The GEON IDV is designed for general purpose display and analysis. It can be used for tracking marine mammals, or to show dust storms on Mars. It can be used for GCM climate model results, or soil chemistry in Nebraska. It can show mantle convection for 300 million years, or an hour of aftershocks.
- Full 3D Data can have any location or extent in latitude, longitude, and altitude. The IDV works from the inner core to the stratosphere (and on other planets). Any region and vertical scale may be used. Polar maps are provided.
- Data Interoperability Most data located in latitude/longitude/altitude can be used in the IDV (with data reformatting required in some cases). The IDV handles map projections and unit conversions. You can simultaneously display many kinds of data in one display, all uniformly mapped together.
- Internet Ready - Cyberinfrastructure The IDV is designed to access data online with data portals and with HTML file transfers, FTP, OPeNDAP (DODS), THREDDS, and web services (rest and WMS). Development continues to add WSDL/SOAP connectivity.
- GEON IDV for Geoscience The GEON IDV includes special symbols and plots of geoscience data, such as GPS plate velocity vectors with error ellipses, and earthquake focal mechanisms. You can display geological vertical cross sections in the same 3D display with a geology map on topographic relief. We can add other special symbols as needed.
- Data Available UNAVCO is continually finding free data online, for use in the GEON IDV, and showing how to get it, in this web site.
With the GEON IDV you can
Explore complex earth science data Display earth science data Make computations with multiple data sources Explore Your Data
Modern data sources are often complex and intricate, including 3D structures in depth, mutiple data sources, and time variations. The GEON IDV lets you examine any earth-mapped data with a fully interactive 3D display, including any viewpoint and zoom and full time animation control. Special symbols used in geophysics are built into the GEON IDV. Data from diverse sources and instruments in the same display show inter-relationships. Time animation in 3D of structures is very persuasive.
With true 3D displays and multiple data sources and time steps, and with interactive control of point of view, zoom, rotation, color tables, vertical scale, map projection, and time animation, you will discovery otherwise hidden details, features, and relationships in your data, and with other geophysics data.
Display Earth science data
The GEON IDV is designed for earth science data with latitude and longitude, and optionally time and depth or altitude. The IDV displays are in 2D or 3D, and support simultaneous displays of several data sets from differing sources, with complete control over colors, time animation, map projection, map area, point of view etc. The GEON IDV displays any earth-located grid or point data, images, GIS shape files, and several other types of data.
The GEON IDV has symbols and displays for GPS velocity vectors, seismic tomography, earthquake focal mechanisms, earthquake locations, earthquakes colored and sized by magnitude or depth, seismic ray paths in 3D, seismic anisotropy, convection model visualization, earth strain axes and strain field imagery, and high-resolution 3D topographic relief maps. Multiple data sources and display types may appear in one view.
Compute with multiple data sources
The IDV is also provides data computations and analysis, including a facility to do computations with formulas written in the Python language. You can easily use multiple data sets from different sources - the IDV automatically takes care of grids with different coverages and data location grid points, and units conversions; you don't need to do anything like that. Just enter "A-B" and see the difference between two 3D grids in a 3D view; even if the grids have different sizes, grid spacings, and different data units.
Origins of the GEON IDV
The GEON IDV is an extension of the Unidata IDV (Integrated Data Viewer). Unidata is part of UCAR, a top national meteorological research center funded by the NSF, in Boulder Colorado. Unidata has been a creator of top science software for earth science data display, analysis, and management for more than 17 years.
The Unidata Integrated Data Viewer (IDV) is a "meteorologically oriented, platform- independent application for visualization and analysis." This site describes and provides the GEON IDV, an extension of the Unidata IDV, with additions by UNAVCO to meet the needs of the solid earth science community.
GEON is a five-year multi-institutional NSF large Information Technology Research (ITR), a scientist-centered cyberinfrastructure that will provide earth scientists with a growing array of tools, including data access and integration mechanisms, computational resources, and integrated software for analysis, modeling, and visualization.
