Leica Geosystems (formerly known as Wild Heerbrugg or just Wild) based in eastern Switzerland produces products and systems for surveying and geographical measurement (geomatics). Its products employ a variety of technologies including GPS satellite navigation and laser rangefinders to enable users to model existing structures, terrains in computer based systems to high accuracies, often under 1 cm. The brand Leica, better known for its high quality cameras, was formed on 2 April 1990 after the merger of several companies. In 2005, the company was acquired by Hexagon AB. Leica was listed on the Swiss stock exchange until the 7 August 2006 which saw the cancellation of all publicly held registered shares in Leica Geosystems Holdings Ltd and delisting of all listed registered shares of a par value of CHF 50.
