GEMPAK, the GEneral Meteorology PAcKage, is an analysis, display, and product generation package for meteorological data. It is developed by NCEP (the National Centers for Environmental Prediction) for use by the National Centers (Storm Prediction Center (SPC), Tropical Prediction Center (TPC), Aviation Weather Center (AWC), Hydrologic Prediction Center (HPC), Marine Prediction Center (MPC), Environmental Modeling Center (EMC), etc.) in producing operational forecast and analysis products such as those distributed as Redbook Graphics and others displayed on the NWS web pages and utilized internally within the centers. Graphical User Interfaces provide convenient access to interactive data manipulation. A comprehensive set of decoders enables integration of real-time and archive data, products, and bulletins. The GEMPAK distribution consists of a suite of application programs, Graphical User Interfaces (GUIs), meteorologic computation libraries, graphic display interfaces, and device drivers for the decoding, analysis, display and diagnosis of geo-referenced and meteorological data.

Fragstats
Comparable:
FRAGSTATS is a computer software program designed to compute a wide variety of landscape metrics for categorical map patterns. It interfaces with ArcGIS and supports and a variety of sampling methods for analyzing sub-landscapes. It accepts raster images in a variety of formats, including ASCII grid, 8-, 16- and 32-bit integer grids, ESRI grid (or raster), GeoTIFF grid, VTP binary terrain format grid, ESRI header labelled grid, ERDAS Imagine grid, PCRaster grid, and SAGA GIS binary format grid. Support for the latter six image formats is via the GDAL library.

IDV
The Integrated Data Viewer (IDV) is a Java-based software framework for analyzing and visualizing geoscience data. IDV is developed at the Unidata Program Center (UPC), part of the University Corporation for Atmospheric Research (UCAR), Boulder, Colorado, which is funded by the National Science Foundation. 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.
