BOREAS TE-18: Landsat Classification of Northern Study Area

A Landsat-5 Thematic Mapper classification image characterizes land cover for the Northern Study Area (NSA) of the BOREAS project. The classification was produced using a supervised maximum likelihood approach on imagery from August 20, 1988. Companion files include example thumbnail images and a viewer utility.

Use Cases

• Analyzing boreal forest land cover types based on the supervised classification.
• Validating ecological models using the 1988 geospatial land cover data.
• Assessing changes in land cover by comparing this historical classification to newer imagery.

Strengths

• Derived from a specific Landsat-5 TM image captured on 20-Aug-1988.
• Produced using a standard supervised maximum likelihood classification method.
• Hosted by NASA and available on multiple data platforms, indicating established provenance.

Limitations

• Column names and exact data structure are unknown from available metadata.
• Conflicting 'last updated' dates: one source lists 2026-03-13, another lists the original 1988 date.
• Dataset size and row count are unspecified across all sources.
