A compact high-definition hyperspectral imaging system (HDHIS) for light aircraft remote sensing to perform concurrent pushbroom hyperspectral imaging and high-resolution photographic imaging. The HDHIS comprises a sensor head having a hyperspectral scanner and a CCD digital camera. An airborne computer interfaces with the sensor head to provide data acquisition including hyperspectral quick view images and control functions. An alternative embodiment includes combining the HDHIS with a computerized airborne multi-camera imaging system (CAMIS) which comprises four progressive scan (CCD) cameras attached to a set of interchangeable, interference filters, to provide a triple spectral imaging system that can be operated by one person on a light aircraft.
