This command line argument runs the DN_Reader
  • -DN/347/129FreeComment
  • -DN/347/129FreeComment 
  • -DN/347/129/3FreeComment
  • -DN/Row/Line/WinRadDN_FreeComment
  • -DNshp  specified by a point shapefile named DN.shp
  • FreeComment is optional 
  • Shall display on screen the spectral signature of the specified pixel,
    • Raw______DN: the raw DN at that location
    • Smoothed_DN: the average of N pixels inside a circular smoothing window around that location
    • Minimum_DN: inside a circular smoothing window around that location
  • Incompatible with -E or -d/D options
  • WinRadDN is optional: sets the radius of the circular smoothing window
    • by default it is set at 5: that's 81 pixels inside a circle 11 pixels in diameter
    • may be set <=5 with WinRadDN for a smaller target
      • 5 ==> N=81 pixels
      • 4 ==> N=49 pixels
      • 3 ==> N=29 pixels
      • 2 ==> N=13 pixels
      • 1 ==> N=  5 pixels
 
The result is printed on the screen
