The thing is: For a N bands 16 bits raw image, you need
That is at least 4*N + 14. For a 3 bands U8 SPOT image,
For a 4 bands U8 Landsat TM image
For a 6 bands U16 Landsat 8 image

![]() | channels 1, 2, 3 Tarawa-subset_Raw_Image a spectral raw image subset, heavily glinted. |
OpenEV pseudo-color pallets=====>>>>> They are located in ./4sm.calls/pct=====>>>>> | ![]() |
![]() | channel_4 Tarawa-subset_mSE this is the special effects mask
|
![]() | channel_5 Tarawa-subset_WZ with following codes
|
![]() | channel_6 Tarawa-subset_WR Smoothing Window Radius (kernel) with following codes
|
![]() | channel_7 Tarawa-subset_Z250 Depths in decimeters, range 1-250 with following codes
|
![]() | channel_8 Tarawa-subset_Z20 Depths in decimeters coded for screen display of no interest here as the depth does not exceed 25 m
|
![]() | channel_9 Tarawa-subset_B Average Bottom Reflectance is scaled from 0 to 200 |
.... | channel_10 Bottom typing not in use with SPOT XS images |
.... | channels 11, 12, 13, 14 are of no interest for a SPOT XS image |
![]() | channels 15, 16, 17
|
......... | channels 18, 19, 20, 21 are void , available for future use |
![]() | channels 22, 23, 24 contain the smoothed/deglinted image Tarawa-subset_Smoothed_Deglinted a spectral image in NATURAL radiances, HistEq enhancement using -E.shp shapefile, subwindow -E100/550/200/400 is not deglinted. |
![]() | channels 25, 26, 2727 contain the water column corrected reflectance Tarawa-subset_Spectral_Bottom_Reflectance A spectral image, scaled from 0 to 250. Of no interest for an image without a Blue band. |
![]() | channel_28 Tarawa-subset_Z_in_centimeters Of no interest here as depths do not exceed 15-20 m inside the lagoon. But this channel is used upon seatruthing |
