Unidata's Integrated Data Viewer
The Integrated Data Viewer (IDV) is a software framework for analyzing and visualizing geoscience data sets collected by the Unidata Program. The IDV may be used to display and analyze satellite imagery, gridded data, surface observations, balloon soundings, radar data and more. Most of the data are provided in real time or near-real time. The IDV can display data anywhere on the globe with a wide selection of map projections and map backgrounds including a 3D spherical globe. Over 20 kinds of 2D and 3D data displays allow users to create cross-sections, profiles, animations and value read-outs of multi-dimensional data sets. A useful feature of the site is the ability to save displays in "bundle" files for use in classroom and lab exercises. Thorough and easy-to-follow directions for IDV installation and use are provided and annual training workshops are offered by Unidata. The data viewer is available for a free download, and data sets are available to participants who are affiliated with a degree-granting institution or a non-profit institution with an education and/or research mission. This resource is part of the Using Data collection.
