EuroSAT Land Cover Classifier (ResNet50)

Model Details

• Base model: ResNet50, pretrained on ImageNet (IMAGENET1K_V2 weights via torchvision)
• Training approach: final layer trained first (backbone frozen), then full fine-tuning at lower learning rate
• Input: 224x224 RGB images, normalized with ImageNet mean/std
• Output: 10-class softmax (see label map below)

Performance (EuroSAT official test split, 2,700 images)

• Overall test accuracy: 98%
• Weakest classes: PermanentCrop (F1 0.96), AnnualCrop (F1 0.96)
• Strongest classes: Residential, SeaLake (F1 1.00)

Limitations

• Trained on European Sentinel-2 imagery; accuracy may degrade on other regions/sensors.
• 64x64 patch size limits detection of small-scale land features.
• RGB-only (no multispectral bands), which loses some vegetation-discriminating signal.
• Confusion observed between agricultural sub-classes (AnnualCrop/PermanentCrop/Pasture) and an unexpected River-to-AnnualCrop misclassification pattern (see confusion matrix).
