Binary Land-Cover Marker Examples
Agricultural field with built-up structures
Description
The first example, FOI = 92287319, is claimed to be an agricultural area. However, using the binary land-cover marker approach outlined above, we have found that part of the FOI is likely covered with artificial surfaces.
Key findings:
The built-up mask (applied to Sentinel-2) clearly shows artificial structures within the agricultural area
This finding is confirmed by the timelapse component in the bottom right corner of the screen
External validation through Roads and building detection corroborates the presence of built-up structures

Artificial surface with consistently low NDVI
Description
The second example, FOI = 92288632, is also claimed to be arable land. However, we can clearly see from the example that the FOI is inconsistent with this claim due to consistently low NDVI values throughout the year.
Key findings:
Constantly low NDVI values indicate absence of healthy vegetation
The temporal pattern is inconsistent with typical agricultural land use
Visual inspection confirms the presence of artificial surfaces rather than agricultural activity
