Integrated Data Viewer (IDV) is a Java-based software framework for analyzing and visualizing geoscience data. IDV includes a software library and a reference application made from that software. It uses the VisAD (http://www.ssec.wisc.edu/~billh/visad.html) and netCDF-Java (http://www.unidata.ucar.edu/software/netcdf-java) libraries and other Java-based utility packages.
The IDV "reference application" is a geoscience display and analysis software system with many of the standard data displays that other Unidata software (e.g. GEMPAK and McIDAS) provide. It brings together the ability to display and work with satellite imagery, gridded data (for example, numerical weather prediction model output), surface observations, balloon soundings, NWS WSR-88D Level II and Level III RADAR data, and NOAA National Profiler Network data, all within a unified interface. It also provides 3-D views of the earth system and allows users to interactively slice, dice, and probe the data, creating cross-sections, profiles, animations and value read-outs of multi-dimensional data sets. The IDV can display any Earth-located data if it is provided in a known format (see Data Sources).
