Forest Insect Damage Survey Data From Aerial And Satellite Monitoring

Annual surveys since 1967 track damage caused by forest livery insects to trees. The Ministry of Natural Resources and Forests of Québec conducts these surveys, integrating satellite imagery from 2024. Data is updated yearly only when new damage is observed.

Use Cases

• Classify forest livery damage severity levels using annual aerial survey polygons.
• Model the spatial spread of insect outbreaks over time using geotiff layers from different years.
• Correlate observed damage areas with environmental variables like forest type and climate data.
• Validate satellite-based disturbance detection algorithms against ground-surveyed SHP data.

Strengths

• Long-term monitoring program with data collection starting in 1967.
• Multi-source data integration combining historical aerial surveys and modern satellite imagery from 2024.
• Annual update cycle ensures detection of new damage events.

Limitations

• Data is only updated in years when damage is observed, creating potential temporal gaps.
• Specific metrics on row count, spatial resolution, or damage quantification are not provided.
• Automated translation of metadata may introduce inaccuracies in field descriptions.
