Global Forest Cover Change Tree Cover at 30m Resolution for 2000-2015

Global tree canopy data at 30-meter resolution derived from Landsat 5 and 7 satellite imagery. The dataset is available for four epochs centered on 2000, 2005, 2010, and 2015 and was produced by NASA's Land Processes DAAC under the MEaSUREs program. It includes tree cover layers, error estimates, and provenance information to support analysis of forest changes.

Use Cases

• Modeling deforestation and reforestation trends based on multi-epoch tree cover layers.
• Assessing uncertainty in forest change estimates using the provided tree cover error files.
• Validating other land cover products using the high-resolution Landsat-derived canopy information.

Strengths

• Data is derived from high-resolution Landsat 5 TM and Landsat 7 ETM+ imagery at 30 meters.
• Provides four epochs of data centered on 2000, 2005, 2010, and 2015 for change analysis.
• Includes ancillary files for uncertainty (error) and provenance, enhancing analytical rigor.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The index file and file list were not generated for the 2015 epoch, as noted in the description.
