TCC, linear enhancement
Very dark, though, in spite of clear sky.
This is June, early winter in Perth.
End spring might be better for sun illumination.
TCC, logarithmic enhancement
Not any more!
Note the ominous dark area north of Success Bank:
this smacks of negative bottom contrast
"Cockburn Sound has developed within an elongate depression that forms a margin between the Swan
Coastal Plain and the Rottnest Shelf, known as the Cockburn-Warnbro Depression (Fig. 2)"
|All we can do in 4SM is try to save the day: ||The city of Perth spews |
urban, riverine and industrial pollution
into the atmosphere and waters.
This very much looks like
a desperate case for 4SM shallow water work,
which uses a simplified radiative transfer equation.
PAN, histeq enhancement
NIR1 830 nm, histeq enhancement
PAN, smart-smoothed, histeq enhancement
Trade off, hands on
My personal views
For shallow water work,
the specification of the future WV sensors
for Blue, Green, Yellow and Red bands
