Addition of NDVI profiles
The option to display NDVI profiles has been added to LACO-Wiki, which can help in visual interpretation, particularly for those land cover classes that are difficult to differentiate from the satellite imagery alone or that have a seasonal component.
To add NDVI profiles to a validation session, this feature must first be enabled when creating the session. An example is shown in Figure 16 in which the Vegetation indices check box is turned on if NDVI profiles are to be displayed.
Once you enter the validation session, two sets of NDVI profiles will appear below the main validation area, as shown in Figure 17. The chart on the left shows a time series of 32-day composites from Landsat 7 and 8, a 16-day composite from MODIS and daily time series from the PROBA-V satellite. On the right is the average NDVI from each of these sources.
