Reveal Previously Hidden Classifications to Get More Out of Visualizations in Worldview

View a list of the layers that now show previously hidden pixel classifications.

Worldview is now providing users with the ability to toggle on/off classifications that were previously hidden to the user as transparent pixel values.

In the example below, the Sea Ice Extent layer previously showed only the sea ice values (Figure 1), but the colormap included other potentially interesting and useful classifications, such as Cloud, Land, Missing Data, etc. Users can now toggle on/off these other classifications (Figure 2) to show relevant information like the location of clouds that may obscure sea ice. Now users have more contextual information to assess these visualizations.

Figure 1: Sea Ice classification layer from the MODIS instrument aboard the Terra satellite. Sea ice is shown in dark pink, overlaid on a corrected reflectance image from the same satellite and sensor.

Figure 2. Sea Ice classification layer from the MODIS instrument aboard the Terra satellite. Sea ice is shown in dark pink, cloud in light blue, ocean in dark blue, and land in green. With these other classifications displayed, we now have a better idea of what areas that may have had sea ice were actually obscured by cloud, and the areas that are land masses.
