British Columbia Dominant Tree Species Map and Likelihoods at 30m Resolution, 2015

72% overall accuracy was reported for species occupying 80% of the forested areas. The dataset maps dominant tree species and class membership likelihoods for British Columbia in 2015, derived from Landsat time series and ancillary data using a Random Forests classifier. It was developed by Natural Resources Canada within the National Terrestrial Ecosystem Monitoring System framework.

Use Cases

• Modeling forest composition and change based on dominant species maps.
• Assessing classification uncertainty for land cover based on class membership likelihoods.
• Analyzing the impact of topography and disturbance on species distribution based on predictor variables.
• Validating or extending ground-based forest inventories with wall-to-wall satellite-derived maps.

Strengths

• Provides a wall-to-wall map at a 30-meter spatial resolution.
• Includes class membership likelihoods to quantify prediction uncertainty.
• Achieved an overall accuracy of 72% for species covering 80% of forested areas.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's specific row count and file size are unknown, which may limit suitability assessment.
