Quebec City Urban Change Detection from Satellite Imagery, 2006 and 2022

Natural Resources Canada provides a temporal analysis of changes in Quebec City based on GeoAI features automatically extracted from satellite images acquired in 2006 and 2022. Simple geospatial analysis enables the detection of features present in 2022 that were not there in 2006. The addition of new buildings is highlighted as an indicator of urban development and sprawl.

Use Cases

• Monitor urban sprawl based on the detection of new buildings between 2006 and 2022.
• Analyze long-term land-use change trends in Canadian cities based on temporal satellite imagery.
• Train machine learning models for automated feature extraction and change detection from satellite data.

Strengths

• Data is provided by Natural Resources Canada, a federal government agency.
• Covers a 16-year time span between 2006 and 2022 for longitudinal analysis.
• Focuses on high-resolution satellite imagery for detailed change detection.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• The series is described as 'fairly new' with limited examples available.
