Southern Gulf Islands forest ecosystems in British Columbia are analyzed using a nine-year time series of Sentinel-2 multispectral satellite imagery from 2017 to 2025. The dataset, created by MPAYIMANA, Joselyne and harvested from Borealis, compares land-use history and ecosystem health on Mudge Island and Link Island. It includes land cover classifications and annual NDVI calculations to assess the impact of residential fragmentation.
Use Cases
- Tracking forest cover change over time based on the nine-year satellite time series
- Comparing vegetation productivity between islands using the calculated NDVI values
- Assessing ecological resistance to drought stress based on the analysis of the 2021 Pacific Northwest Heat Dome
- Quantifying land cover composition and change using the supervised Random Forest classification results
Strengths
- Nine-year time series from 2017 to 2025 provides longitudinal data
- Land cover classification achieved an overall accuracy of 77.7% (Kappa = 0.68)
- Specific quantitative results are provided, such as an 11.2 ha forest cover decline on Mudge Island
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
