Welcome to the McIDAS Website. In existence since 1973, McIDAS (Man computer Interactive Data Access System) is a suite of sophisticated software packages that perform a wide variety of functions with satellite imagery, observational reports, numerical forecasts, and other geophysical data. Those functions include displaying, analyzing, interpreting, acquiring and managing the data. [more]

This website, administered by McIDAS User Services at the Space Science and Engineering Center (SSEC) of the University of Wisconsin-Madison, has a variety of uses, including:

• information for visitors interested in learning about the McIDAS software packages
• access to software, documentation and other information for McIDAS Users' Group members
• access to these free software packages: McIDAS-V (an alpha version of the successor to McIDAS-X [SSEC's flagship visualization and data analysis software package]), McIDAS-Lite (a satellite image viewer for working with McIDAS areas or MODIS HDF files), and OpenADDE (a package used to serve geophysical data to client workstations)
