Intergraph software products include the computer-aided dispatch (CAD) application I/CAD, the geographic information system (GIS) application GeoMedia, the image processing application ERDAS IMAGINE, the photogrammetry application ImageStation and the InService outage managements system for electrical utilities. ==History== Intergraph was founded in 1969 as M&S Computing, Inc., by former IBM engineers who had been working with NASA and the U.S. Army in developing systems that would apply digital computing to real-time missile guidance. The company was later renamed to ''Intergraph Corporation'' in 1980. In 2000, Intergraph exited the hardware business and became purely a software company. On July 21, 2000, it sold its Intense3D graphics accelerator division to 3Dlabs, and its workstation and server division to Silicon Graphics. On November 29, 2006, Intergraph was acquired by an investor group led by Hellman & Friedman LLC, Texas Pacific Group and JMI Equity, making the company privately held. On October 28, 2010, Intergraph was acquired by Hexagon AB.〔(【引用サイトリンク】title=Hexagon AB - Press release )〕 The transaction marks the return of Intergraph as part of a publicly traded company.
