  • ITRES Begins Integrating POS/AV with Hyperspectral CASI

    ITRES begins to use the new Position Orientation System (POS) developed by Applanix Corp. with its CASI-1 hyperspectral imager. The POS, providing precise roll, pitch, heading, and position data, replaced the use of the two-axis vertical gyroscope used with earlier CASI-1 systems.

  • 1996: ITRES Operations Group Established

    To further develop the still-growing global commercial hyperspectral market, ITRES established an Operations Group skilled in all aspects of couducting airborne surveys globally for environmental applications.

    In the first few years following the group’s establishment, projects were conducted in the U.S., Canada, Europe, South America, Australia, and Asia.
