Backscatter Colour Map
For Nortek and RDI ADCP daily current plot products (PNG and PDF formats) and echosounder backscatter plots (ASL, BioSonics)
This option allows the user to select the colourmap used for the backscatter plot. An example of each colourmap available is displayed below, along with the Oceans 3.0 API filter for that specific colourmap.
Default (ONC/VENUS rainbow/jet colours)
Oceans 3.0 API filter:
dpo_backScatterColourmap=0
Modified Default (perceptually smooth rainbow/jet colours from m_map toolbox)
Oceans 3.0 API filter:
dpo_backScatterColourmap=1
