Hand-held spectroradiometer for ground-level<br />
measurement of spectral reflectance<br />
• There are several <br />
brands of hand-‐held <br />
radiometers that <br />
mimic the sensors in <br />
satellites. <br />
• Some have four <br />
sensors that can be <br />
set to sense the same <br />
band widths as <br />
common satellite <br />
sensors. <br />
• Most of the newer <br />
ones have large <br />
numbers of channels <br />
(ASD instruments <br />
have 256 channels). <br />
