I am doing a research that involves aerial photography, specifically forest surveying. In one paper, "Automated tree crown delineation from imagery based on morphological techniques", I found this sentence where they describe the equipment used:
The aerial multispectral imagery [...] was acquired [...] using an Illunis XMV-4021C camera at three broad spectral bands: blue (with center wavelength of 450 nm), green (550 nm), and red (625 nm).
I couldn't find any information about that particular camera, nor anything related "broad spectral bands".
Is the camera described in the paper substantially different from a standard consumer compact camera with a CMOS sensor, e.g. a Canon IXUS? If yes, on which spectral aspects?
