MakePIX

• MakePIX: to create a PCIDSK formated image
• Import: to import raw data
• MakeLand: to segment the dry land in the image
• Recode: to segment the image into deep waters, shallow waters, clouds, etc
   

Prepare
to run either of the following processes
 

• Scale 16-bits data into 8-bits data, write out a scaled image
• Delimb remove limb brightening from raw CASI flightlines
• Fill occasional No_Data pixels through a smoothing process, and write a "filled" spectral image, either 16-bits or 8-bits
• Linearize linearize the data and write out a "linearized" 8-bits spectral image.

Deglint
to deglint the image
 

• 2: a deglint tolerance threshold
• 3_14: deglinting is based on channel_3
  • only pixels with Ls3<=14 shall be deglinted
• FN...: deglinting may be restricted to a selection of flight lines in a mosaic
• 1_255: controls the deglint parameters training sites
• 570_640_200_400: a rectangular area where glint calibration parameters shall be estimated

• also writes a linearized image

Extract
to extract image data for the purpose of optical calibration

• U8 data is 8-bits unsigned radiance.
• 3max255
  • 3max255 shall accept all pixels for the BPL.
  • 3max5 would restrict extraction of BPL data to pixels which read less than Lsw[3]+5 in band 3. This feature excludes heavily glinted pixels from the calibration textfile, so that the BPL appears more clearly.
• mBPL
  • mBPL_1 only accept pixels masked under the 1-20 code range in mask mSE.
  • mBPL_2 only accept pixels masked under the 2-20 code range in mask mSE: this is how pixels masked at 1 are excluded.
• mSOIL_21 only accept pixels masked at 21 to make out the Soils Line.
• mSHAL
• M(m)ask_2 in the -model argument:
  • only accept pixels masked under the 2-20 code range in mask mSE: this is how pixels masked at 1 are excluded. This overwrites the mBPL variable.
  • same as mBPL2, but writes a calibration textfile image_m2.cal instead of image_m0.cal

Calibrate
to run the Calibrator module
 

• BdSMpZ a syntax to take control on what is going to be plotted
• 3_2_1 to specify which bands are to be calibrated.
• BDH_12_23 to plot the bidimensional histograms of shallow water pixels examined for extraction of the BPL. Scatterplots of band 1 vs 2 and of band 2 vs 3 are specified here.
• bDH_12_23 would disable the BiDim Histogram tool.

Model
To run the Modeler module
 

• Smooth_4d/Smart_1+ :shall smooth the shallow pixels through a "smart-smoothing" scheme, i.e. an "edge-preserving" process.
  • Deep water pixels shall NOT be smoothed (saves time).
  •  + or -, to enable/disable smart-smoothing of bright pixels.
• Smooth_4D/smart_1+ :shall smooth the shallow pixels through a plain smoothing with a smoothing window radius of 4.
  • Deep water pixels shall be smoothed as well.
• mask_2: mask mSE shall NOT be used to restrict area to be processed.
• Mask_2: mask mSE shall be used to process ONLY pixels under mSE==2, while other shallow pixels are simply duplicated from previous processing.
