Collect and label imagery
Assemble time-series satellite tiles with georeferenced labels for cleared areas and verify labels with domain experts or high-resolution surveys.
Detect deforestation from imagery. Assess localisation and error types.
Detecting deforestation from satellite imagery is a visual classification or segmentation task that flags cleared areas across time. Important issues include cloud cover, seasonal changes, varying sensor resolutions, georeferencing errors and the high cost of false negatives in conservation monitoring.

Detecting deforestation from satellite imagery is a visual classification or segmentation task that flags cleared areas across time. Important issues include cloud cover, seasonal changes, varying sensor resolutions, georeferencing errors and the high cost of false negatives in conservation monitoring.
A proposed application: a monitoring dashboard for environmental teams that highlights new clearings for human review. The system should surface confidence, imagery timestamps and change thumbnails so analysts verify alerts before action.
Assemble time-series satellite tiles with georeferenced labels for cleared areas and verify labels with domain experts or high-resolution surveys.
Apply cloud masking, normalise sensor bands, mosaic tiles and create change-pairs or stacked inputs for temporal models.
Start with a small classifier or segmentation model (e.g. U-Net or a pretrained encoder) and validate with geographically held-out tiles.
Measure precision/recall (or IoU for segmentation), false-negative rate, and per-region performance to spot bias across ecosystems.
The supplied starter loads scikit-learn's digits dataset (handwritten digit images), splits it into train/test sets, trains a RandomForestClassifier, prints a classification report and displays a confusion matrix for the digit classes. It does not use satellite imagery, geospatial libraries or any deforestation labels.
digits = load_digits()
X_train, X_test, y_train, y_test = train_test_split(
digits.data,
digits.target,
test_size=0.25,
random_state=42,
stratify=digits.target,
)
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)
predictions = model.predict(X_test)The starter uses the sklearn digits dataset (handwritten numerals) rather than satellite imagery and trains a multiclass RandomForest on those digit labels. Therefore it does not implement image segmentation, change-detection, georeferencing or any deforestation-specific preprocessing; its evaluation on digits cannot be used to judge deforestation performance.
A pilot could use openly licensed satellite tiles (e.g. Sentinel-2), create time-differenced patches and train a segmentation or change-detection model. Add an analyst review interface that shows before/after thumbnails, confidence scores and easy tools for correcting alerts.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
