The colour palette used in the biomass view is set to a default of red for any vegetation density readings of 0.2 and below (which means there’s almost no plant density on the ground), and goes up to purple for readings of vegetation density readings of 0.8 and above (which represents almost full plant ground cover).
Changing DecipherAg’s colour stretch lets you shift how the colour palette is distributed in the biomass view across the map, which means you can increase the detail you see of any biomass variability in your chosen location.
For example, in low vegetation density locations, shortening the colour stretch means you’ll be able to see greater contrast between the different areas.
To adjust the colour stretch:
- Go to imagery in the side panel on the left of your screen.
- Select one of the ‘Low’, ‘Standard’ or ‘High’ presets in the biomass view menu according to whether the vegetation density is low, standard or high in your selected location.
- For even greater control, you can also use the slider to create a custom value from 0 to 1.
