Ecosystem Classification of the Hudson Bay Lowlands via Landsat Imagery

A 2026 classification product from Environment and Climate Change Canada mapping ecosystems in the Hudson Bay Lowlands. It was produced using Classification by Progressive Generalization (CPG) on enhanced false-colour Landsat imagery. The dataset supports international reporting on biodiversity, carbon stocks, and climate change.

Use Cases

• Quantifying carbon sinks and stocks for national greenhouse gas reporting based on ecosystem-type inputs.
• Monitoring ecosystem change and vulnerability to rapid warming and permafrost shifts.
• Assessing risks to biodiversity, including migratory birds and polar bears, using spatially explicit mapping.
• Supporting progress reporting for the Kunming-Montreal Global Biodiversity Framework based on ecosystem extent indicators.

Strengths

• Produced by Environment and Climate Change Canada, a national authority.
• Uses a detailed CPG method involving K-means clustering to reduce millions of spectral signatures to 200 clusters.
• Explicitly designed to meet Canada's international reporting obligations under UNFCCC and CBD frameworks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Freshness should be verified despite the last update date of 2026-04-22.
