Remote sensing
Along
Earth science; Remote sensing
Track scanner-Scanner with a linear array of detectors oriented normal to flight path. The IFOV of each detector sweeps a path parallel with the flight direction.
Wien's displacement law
Earth science; Remote sensing
Describes the shift of the radiant power peak to shorter wavelengths as temperature increases.
Rectilinear
Earth science; Remote sensing
Refers to images with no geometric distortion in which the scales in the horizontal and vertical directions are identical.
Scanner
Earth science; Remote sensing
An imaging system in which the IFOV of one or more detectors is swept across the terrain.
Seasat
Earth science; Remote sensing
NASA unmanned satellite that acquired L-band radar images in 1978.
Periodic line striping
Earth science; Remote sensing
Defect on Landsat MSS or TM images in which every sixth or sixteenth scan line is brighter or darker than the others. Caused by the sensitivity of one detector being higher or lower than the others.
Supervised classification
Earth science; Remote sensing
Digital-information extraction technique in which the operator provides training-site information that the computer uses to assign pixels to categories.
