1. McIDAS Celebrates 30th Anniversary
October 2003 marked the 30th anniversary of the McIDAS (Man computer Interactive Data Access System) software. In development since 1970 and first used to display and analyze satellite data in 1973, it is still used by meteorological agencies around the world to display and manipulate weather data.
We believe that McIDAS may be the oldest, continually used, and supported software package in existence anywhere.
