In 2019, Harris Corporation merged with 元 Technologies, Inc. Exelis Visual Information Solutions was purchased by Harris Corporation in 2015, becoming a subsidiary known as Harris Geospatial Solutions, Inc. ITT Visual Information Solutions was renamed again to the current Exelis Visual Information Solutions. along with ITT Defense and Information Solutions. In 2011, ITT Corporation was divided into three standalone companies, and ITT Visual Information Solutions became part of Exelis Inc. Four years later, RSI along with the Remote Sensing Systems division of Eastman Kodak, were sold to ITT Corporation and were renamed ITT Visual Information Solutions. RSI was acquired by Eastman Kodak as a wholly owned subsidiary in 2000.
Written in IDL, ENVI is the industry standard for image processing and analysis allowing GIS professionals, remote sensing scientists, and image analysts to extract information from geospatial imagery. In 1994, the software package ENVI was released. NASA Goddard Space Center and Ball Aerospace were among the company's early customers. (RSI) and released IDL as a proprietary programming language for visualizing data. As his vision developed, Stern left the university and started working in his attic to improve the programming language. Stern developed a programming language called Mariner Mars Spectral Editor, which later evolved to IDL, Interactive Data Language, in order to supplement FORTRAN, specifically for data analysis and visualization. The company's origin can be traced back to 1977 when David Stern was working at the University of Colorado on the Mariner Mars space probes.
