Secondary Forest Biomass and Age Class Maps for Rondonia, Brazil

LBA-ECO CD-37 provides maps and estimates of above-ground live woody biomass (AGLB) and forest age for secondary forests in Rondonia, Brazil. The dataset was created by ORNL_CLOUD using the Threshold Age Mapping Algorithm on Landsat imagery from 1975 to 2003, combined with biomass estimates from the Geoscience Laser Altimeter System (GLAS). It includes five raster images and three comma-delimited data files.

Use Cases

• Estimating carbon stocks in secondary forests using the above-ground live woody biomass (AGLB) data.
• Analyzing forest regrowth patterns over time using the tree age and forest formation classification maps.
• Validating ecological models of tropical forest succession with the derived forest type and age classification maps.
• Assessing landscape-level biomass recovery following deforestation using the combined raster and tabular data.

Strengths

• Provides a 28-year temporal series (1975-2003) of Landsat imagery for change detection.
• Integrates two distinct remote sensing methods: Landsat-based classification and GLAS lidar biomass estimates.
• Includes multiple data formats (rasters and tabular files) for different analytical approaches.

Limitations

• Conflicting last updated dates exist across platforms (2003-05-20 vs. 2026-03-13), creating uncertainty about data currency.
• Specific column names and row counts for the tabular data are not provided, limiting detailed assessment of structure.
• The license is ambiguously specified as 'other-license-specified' without clear terms.
