GEON Integrated Data Viewer

image
The GEON Integrated Data Viewer (GEON 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 solid earth sciences. If your data is 2D, 3D, or 4D grids, point observations, vector data, imagery mapped on the Earth, or most any data mapped in or on the Earth, you can explore it with the GEON IDV.

Although the IDV can make impressive 3D displays, it is designed for data exploration and analysis. It is not merely a tool to make illustrations.

The GEON IDV is an extension of the Unidata Integrated Data Viewer (Unidata IDV), using Java plugins and the Unidata IDV’s extensible architecture.

The IDV has interactive, true 3D displays with full time animation where needed, and it also is a powerful tool for cyberinfrastructure, data interoperability, and “data mashups.”

IDV DOCUMENTATION, TUTORIALS and DATA

General Purpose: The GEON IDV is designed for general purpose display and analysis of data in the Earth sciences. It can be used for numerical climate model results, or soil chemistry in Nebraska. It can show mantle tomography, or a movie of a week of aftershocks.

True 3D and time controls: Data can have any location or extent in latitude, longitude, and altitude. The IDV works from the inner core to the stratosphere, and even on other planets. Any region and vertical scale may be used. Time values from seconds to millions of years are recognized.

Data Interoperability: Most data located in latitude/longitude, and optionally altitude and time, can be used in the IDV. 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.

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.

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.


imageCompute 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.

The GEON IDV is an extension of the Unidata IDV (Integrated Data Viewer). The GEON IDV is created and maintained by UNAVCO with GEON funding. Unidata is part of UCAR, a top national meteorological research center funded by the NSF, in Boulder Colorado.
