Geometric calibration and aerotriangulation of DMSC imagery-preliminary results

Multi-spectral airborne digital imaging systems are becoming ubiquitous tools for environmental and commercial remote sensing applications. Critical to their successful application is rigorous radiometric and geometric calibration. This paper briefly reviews two of the processes involved prior to geometric correction, namely camera calibration and aerotriangulation. This paper describes calibration and triangulation experiments conducted using the Digital Multi-Spectral Camera Mk2 system. Results Indicate that simultaneous triangulation of all spectral-band images yields optimal object point height accuracy relative to single-band image triangulation.
