LBA-ECO ND-01: Land Cover Transition Maps for Rondonia, Brazil

Rondonia, Brazil, is the focus of this dataset, which provides classified land cover transition maps for the Ariquemes, Luiza, and Ji-Paraná areas. The maps depict the age of cleared land relative to the year 2000, derived from Landsat TM and MSS imagery at 30-meter resolution. Temporal changes are represented by 31 TM scenes from 1984-1999 and a pair of MSS scenes from 1975 and 1978.

Use Cases

• Analyzing deforestation rates and patterns based on the age-of-clearing data.
• Modeling land cover change over time using the multi-decade satellite imagery.
• Calibrating regional carbon flux models with historical forest transition data.
• Assessing the impact of agricultural expansion on primary forests in Rondonia.

Strengths

• Provides a 24-year temporal range from 1975 to 1999.
• Uses high-resolution (30m) Landsat TM and MSS imagery.
• Focuses on three specific, well-studied areas within the Brazilian Amazon.

Limitations

• Column names and exact dataset size (rows, file size) are not provided in the metadata.
• There is a conflict in the 'last updated' date between platforms (1999 vs. 2026).
• The license is ambiguously listed as 'other-license-specified'.
