LBA-ECO LC-22: MODIS Deforestation Validation in Mato Grosso

August 2003 to July 2004 field observations, GPS points, and polygons of deforested areas in the Brazilian state of Mato Grosso, between Nova Mutum and Sinop. This dataset was created to validate Moderate Resolution Imaging Spectroradiometer (MODIS) data at 250-meter resolution for deforestation detection. It comprises 16 files, including 10 shapefiles and 6 CSV files.

Use Cases

• Validating MODIS 250m resolution deforestation products based on ground truth observations.
• Assessing the accuracy of satellite-derived land cover classifications using geospatial polygons.
• Analyzing spatial patterns of deforestation in a specific Amazonian region using GPS point data.
• Calibrating or training machine learning models for deforestation detection with field-verified examples.

Strengths

• Provides ground validation data for a key satellite sensor (MODIS) over a one-year period.
• Contains multiple data types (points, polygons, field observations) across 16 files for cross-referencing.
• Originates from a authoritative organization (NASA).

Limitations

• Metadata is incomplete: column names, row counts, and exact file sizes are unknown.
• Conflicting last-update dates exist between platforms (2004 vs. 2026), suggesting potential metadata errors.
• Spatial coverage is limited to a specific corridor in Mato Grosso, Brazil.
