Landsat ETM+ Active Fire Masks for Brazilian Amazon 2001-2003

244 GeoTiff images provide active fire detection data for the Brazilian Amazon from 2001 to 2003. The dataset includes both individual fire pixel masks and clustered fire pixel masks, derived from Landsat 7 ETM+ imagery with a 30-meter spatial resolution. It is produced by ORNL_CLOUD and includes associated text files summarizing fire pixel information.

Use Cases

• Analyzing spatial patterns of vegetation fires using the 30-meter resolution GeoTiff fire masks.
• Studying fire cluster size and distribution via the clustered active fire pixel images with assigned group IDs.
• Correlating fire events with land cover changes using the temporal coverage from 2001-2003.
• Validating regional fire detection algorithms with the provided active fire pixel summary text files.

Strengths

• Contains 244 distinct, high-resolution (30m) geospatial image files for analysis.
• Provides both individual and clustered fire pixel data, enabling pattern analysis at two levels.
• Covers a specific three-year period (2001-2003) during a key era of Amazonian study.
• Data selection was based on quality, availability, and actual fire occurrence, improving relevance.

Limitations

• Conflicting last updated dates exist across platforms (2003-05-23 vs. 2026-03 13), indicating potential metadata inconsistency.
• No column or row counts are provided for the associated summary text files, limiting understanding of tabular data scope.
• The specific license terms under 'other-license-specified' are not detailed.
