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.
high-pass filter
Earth science; Remote sensing
A spatial filter which selectively enhances contrast variations with high spatial frequencies in an image. It improves the sharpness of images and is a method of edge enhancement.
raster
Earth science; Remote sensing
The scanned and illuminated area of a video display, produced by a modulated beam of electrons sweeping the phosphorescent screen line by line from top to bottom at a regular rate of repetition.
rectilinear
Earth science; Remote sensing
Refers to images with no geometric distortion in which the scales in the horizontal and vertical directions are identical.
digital filter
Earth science; Remote sensing
Mathematical procedure for modifying values of numerical data.
