Landsat Imagery Time Series for Rondonia, Brazil 1975-2000

LBA-ECO ND-01 provides a georegistered Landsat time series for five areas in Rondonia, Brazil, from June 1975 to June 2000. The dataset includes 53 total scenes from Multispectral Scanner, Thematic Mapper, and Enhanced Thematic Mapper Plus sensors, coregistered to Brazilian PRODES reference imagery. It was produced by ORNL_CLOUD and includes GeoTIFF files for individual spectral bands alongside calibration data.

Use Cases

• Analyzing deforestation patterns over 25 years using the time series of coregistered Landsat scenes.
• Calibrating spectral reflectance from raw radiance using the provided slope and intercept text files for each scene.
• Assessing land cover change in specific Path/Row areas like Ariquemes (P232,R67) or Ji-Parana (P231,R67).
• Validating georegistration accuracy against the included INPE PRODES Landsat reference scenes.
• Comparing imagery from different Landsat sensor generations (MSS, TM, ETM+) within a consistent geographic framework.

Strengths

• Includes 53 temporally distributed scenes (2 MSS, 45 TM, 6 ETM+) across a 25-year period.
• Scenes are coregistered to PRODES reference imagery with sub-pixel accuracy (within ±1 pixel at 30m resolution).
• Dataset provides calibration parameters (slope and intercept) for converting digital numbers to reflectance.
• Cross-platform presence on NASA EarthData and Data.gov signals established credibility and importance.

Limitations

• Temporal coverage is inconsistent; not all five areas have scenes for every year between 1975 and 2000.
• Sources conflict on the last updated date: one lists 2000-06-28, while others list 2026-03-13 (likely a metadata refresh).
• Specific column names and row counts are not provided, limiting precise understanding of the data structure.
