Syntax_Recode home
This command line argument runs the Recoder HowTo Recode
  • Careful
    • save a copy of OutChannel_N: one never knows...
    • you may overwrite InChannel by OutChannel
  • -Recode/OldVal_InChannel_M_into_NewVal_OutChannel_N
    • for the whole image
  • -Recode/OldVal_InChannel_M_into_NewVal_OutChannel_N/shapefile.shp 
    • a shapefile is optional: recode only according to the features specified in the shapefile
    • a feature may be either
      • up to 255 separate broken lines                 
      • up to 255 separate closed polygons           
      • separate points
    • maximum 1000 waypoints altogether
    • the .shp suffix is optional in the -Recode... argument
    • do not mix lines and/or polygons and/or points in one same shapefile
    • OPENEV is very good at shapefiles
    •  shp2text executable is used by 4SM to convert the shapefile to a textfile, which is then used by 4SM
  • -Recode/GT_5... would recode all pixels GreaterThan_OldVal into NewVal...
  • -Recode/LT_5... would recode all pixels    LesserThan_OldVal into NewVal...
Good luck, and ... don't get confused!
