ABSTRACT
Imagery intelligence is often described as intelligence that is visual: maps, drawings, photographs and other representations of the world in image form. While this often conjures the idea of optical photographs (also known as PHOTINT), 1 the field of imagery intelligence is much broader, including a range of ‘images’ from the reflections cast by the whole electromagnetic spectrum. This ranges from infrared cameras generating images produced by warm bodies, to radar bouncing radio or microwaves off objects to determine their range, altitude, direction or speed, to multi-spectral or hyper-spectral imagery (MSI and HSI) deriving an image from spectral analysis. 2 These advances in technology provide the intelligence analyst with the ability to see, record and evaluate scenes that would otherwise be out of reach.
