BOREAS Follow-On DSP-01: Landsat TM Land Cover Mosaic

Seven Landsat-5 Thematic Mapper images were assembled to create a detailed land cover classification for the BOREAS Transect. A detailed classification scheme was employed to extract virtually all discernible land cover information from the digitally enhanced images. The data product is provided in a binary image format file.

Use Cases

• Analyzing historical land cover change in the BOREAS study region based on the detailed classification scheme.
• Validating or comparing newer land cover models against a high-detail historical baseline for the boreal transect.
• Studying the spatial distribution of vegetation and land use types from a multi-scene mosaic.
• Conducting geospatial analysis of boreal ecosystems using a pre-processed, regionally complete land cover map.

Strengths

• Provides complete coverage of the BOREAS Transect using seven entire Landsat-5 TM scenes.
• Employs a detailed classification scheme designed to extract maximum information from the source imagery.

Limitations

• Critical metadata conflicts: last updated date is reported as both 1998-08-28 and 2026-03-13, creating uncertainty about data provenance and potential modifications.
• Sparse technical documentation; specific classification legend, accuracy assessment, and binary file structure are not described.
• Data format (binary image) may require specialized software or knowledge for access and analysis.
