Abstract :
Optical images provide a useful reference for passive microwave radiometer data. The images need not have state-of-the-art spatial resolution, but they should include positioning data and be produced and manipulated with ease. The paper introduces the HUT pushbroom video imager consisting of a video camera, frame grabber, controlling PC and optional attitude-DGPS. System calibration and pixel geopositioning are discussed, and an example image is presented
