LBA-ECO Land Cover Classes for Uruara, Brazil: 1986-1991

ORNL_CLOUD provides land cover classifications for the Uruara municipality in Para, Brazil, derived from Landsat TM images. The dataset contains five land cover classes across three distinct years: 1986, 1988, and 1991. Data is stored as GeoTIFF files compressed within ZIP archives.

Use Cases

• Analyzing deforestation trends by comparing the 'Forest' and 'Not Forest' class extents across the 1986-1991 time span.
• Assessing water body changes using the 'Water' land cover classification over time.
• Masking out areas of cloud cover or shadow in satellite image analysis for the Uruara region.
• Providing a historical baseline of land surface state for ecological modeling in the Amazon.

Strengths

• Provides multi-temporal coverage with classifications for three specific years (1986, 1988, 1991).
• Land cover classes are derived from Landsat TM imagery, a standard source for land cover mapping.
• Cross-platform presence on NASA EarthData and Data.gov signals recognized importance and curation.

Limitations

• Row count, file size, and specific column/band names are not provided by any source.
• Sources conflict on the 'last updated' metadata, reporting dates from 1999 to 2026.
• The 'course' land cover classification suggests a generalized, lower-resolution product.
