Crop and Land-Use Marker Examples
High confidence in crop group prediction
Description
The first example, FOI = 92278988, is declared as wine (vineyard crop group). The classification marker unequivocally agrees with this declaration, showing 100% confidence that the FOI belongs to the vineyards crop group.
Key findings:
- Perfect match between declared crop type and predicted crop group
- 100% pseudo-probability score indicates very high model confidence
- Visual inspection confirms vineyard characteristics

Lower confidence in crop group prediction
Description
The next example is FOI = 92269936, which is claimed to be corn, belonging to the corn grain and silage (2) crop group. The crop-group marker shows mixed results:
ARPS crop group classification:
- Predicts "other oilseeds" with 80% confidence
Sentinel-2 crop group classification:
- Predicts "corn grain and silage" with 51% confidence (relatively low)
- Alternative prediction: "other oilseeds" with 44% confidence
Technical interpretation: Upon visual inspection, the claim appears correct. The presence of winter crop until late March likely postponed the corn greening period, which may have affected the classification. This example demonstrates the marker's confusion between very similar crops. The confusion between corn and oilseed crops can be attributed to both crop types having high NDVI values during summer, making the classes distinguishable but not trivially separable. Despite the mixed signals, both markers still suggest the claim is reasonable.
