GeoAI Building Change Detection in Trois-Rivières, Québec

Temporal analysis from 2013 and 2021-22 of changes in Trois-Rivières, Québec, based on GeoAI features extracted from satellite images. Natural Resources Canada provides this data, which intersects building features with Statistics Canada's Open Database of Buildings to detect new construction. The dataset is part of a series intended for high-resolution change detection and trend analysis across Canada.

Use Cases

• Detecting urban sprawl based on the addition of new buildings between 2013 and 2021-22.
• Analyzing urban development trends based on temporal satellite imagery analysis.
• Conducting high-resolution change detection based on GeoAI-extracted building features.
• Performing trend analysis for municipal planning based on building construction over time.

Strengths

• Data provides temporal coverage for change detection across two distinct time periods (2013 and 2021-22).
• Analysis leverages a high-resolution, authoritative building database (Statistics Canada's ODB v3).
• The dataset is part of a national GeoAI series from Natural Resources Canada, indicating an institutional effort to expand coverage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The series is described as 'fairly new' with limited examples, which may affect data maturity and completeness.
• Row count is unknown, which may limit suitability assessment for large-scale projects.
