    • Abstract:
      Obtaining sensor orientation by direct measurements is

      a rapidly emerging mapping technology. Modern GPS

      and INS systems allow for the direct determination of

      platform position and orientation at an unprecedented

      accuracy. In airborne surveying, aircraft trajectory and

      platform orientation can be determined at the level of

      few cm and 20-30 arcsec, respectively at an almost

      continuous time scale. The use of such integrated

      GPS/INS systems offers immediate benefits for largeformat

      camera-based airborne surveying by

      substantially reducing the need for ground control and

      by basically eliminating aerial-triangulation, except for

      system calibration. For emerging sensors such as

      LIDAR, RADAR, multi-/hyperspectral imagers,

      however, the use of the direct orientation systems is

      mandatory since indirect methods such as control

      point-based aerial-triangulation are not feasible.

      ODOT Aerial Engineering has been operating an

      airplane with a large-format Zeiss Jena LMK2000

      camera. The introduction of a modern GPS/INS-based

      direct orientation system was not only highly desirable

      for economic reasons, but also mandatory if ODOT

      wanted to keep up with technological developments.

      Since ODOT predominantly performs corridor surveys

      over the highway infrastructure, the use of direct

      orientation makes it even more attractive in this case,

      since the savings due to the elimination of control

      points are quite substantial. By establishing a

      GPS/INS-based direct orientation technology for

      ODOT aerial operations, the foundations was given for

      future imaging sensor extensions such as the

      introduction of LIDAR systems or the like.
