Prairie Grassland Land Cover from Sentinel Imagery, 10m Resolution

Canadian grassland ecosystems are mapped using a standardized, high-resolution land cover classification. Agriculture and Agri-Food Canada developed the series via random forest classification on multi-temporal Sentinel-1 SAR and Sentinel-2 optical imagery. The data, last updated on 2026-05-04, differentiates intact native grasslands from high-disturbance forage systems and includes a confidence layer.

Use Cases

• Quantifying carbon sequestration potential based on the differentiation of intact native grasslands.
• Monitoring biodiversity habitat changes based on temporal land cover classifications.
• Tracking land cover change dynamics for semi-decadal comparisons as mentioned in the description.
• Assessing model confidence for native grassland classification using the provided continuous likelihood layer.

Strengths

• Provides a high-resolution 10-meter categorical land cover raster.
• Includes a companion continuous likelihood layer representing model confidence.
• Uses a standardized classification method applied to multi-temporal Sentinel-1 and Sentinel-2 imagery.
• Differentiates spectrally similar classes critical for carbon and biodiversity modelling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The exact geographic extent and temporal coverage for specific releases are not detailed in the provided metadata.
