ENVI expensive commercial software, and no reasonable student price.
Sensors
Opto-knowledge systems
Imaging spectrometers
Airborne Multispectral
NOAA Airborne Multispectral for Nearshore Habitat Mapping
Turns out they use MS imaging to do near-shore seafloor mapping.
Ocean Imaging is a company that processes satellite data to do things like fish finding as well as monitoring coastal pollution and nearshore processes.
Concepts
Spatial Resolution - Pixel size and count
Spectral Resolution - What bands are covered in the electromagnetic spectrum
Radiometric Resolution - how many bits per pixel
Temporal Resolution -- how often the images are re-captured.
Image segmentation
