BOREAS Landsat TM Level-3p Geocoded Imagery

Four Landsat Thematic Mapper images provide geocoded and scaled at-sensor radiance data for the BOREAS project's Northern and Southern Study Areas. These images, processed with ground control for improved coordinate accuracy, capture land cover and biophysical parameters like FPAR and LAI. The dataset spans from August 1988 to June 1994 and was managed by ORNL_CLOUD.

Use Cases

• Analyzing land cover classification changes in boreal forests using the detailed land cover maps.
• Modeling biophysical parameters like FPAR (Fraction of Absorbed Photosynthetically Active Radiation) and LAI (Leaf Area Index) from the multi-band radiance data.
• Validating and improving the geolocation accuracy of other remotely sensed datasets using the ground-control-processed geographic coordinates.
• Studying radiant energy patterns across the BOREAS NSA and SSA primary study areas over the 1988-1994 period.

Strengths

• Images were processed with ground control information, improving the accuracy of geographic coordinates.
• The dataset provides spatially extensive information over the primary BOREAS study areas (NSA and SSA).
• Covers a multi-year temporal period from 20-Aug-1988 to 07-Jun-1994.

Limitations

• Sources conflict on the last update date, reporting either 1994-07-07 or 2026-03-13.
• Band count is inconsistent across images; three images contain only 3 bands while one (07-Jun-1994) contains 7 bands.
• Specific column names, row counts, and file sizes are not provided by any source.
