Agricultural Zone Inclusion and Exclusion Decisions in Quebec

Polygon data represents Commission decisions modifying agricultural zone boundaries in Quebec. The dataset tracks inclusions that add land to the agricultural zone and exclusions that remove it, sourced from topographic data, cadastral compilations, orthophotos, and plans. Decisions are registered over time, with later file numbers superseding earlier overlapping areas.

Use Cases

• Analyze spatial patterns of agricultural zone boundary changes using polygon geometry data.
• Track the temporal sequence of inclusion and exclusion decisions to understand regulatory evolution.
• Validate decision positioning by cross-referencing polygon data with attached plan documents.
• Identify areas of partial or total superposition where later file numbers represent the final result.

Strengths

• Data is derived from authoritative reference documents including the Quebec topographic data base (BDTQ) at 1:20,000 scale.
• Includes both inclusion and exclusion polygons, providing a complete view of agricultural zone modifications.
• Decisions are registered with timestamps, allowing for temporal analysis of boundary changes.

Limitations

• There may be a lag of several months between a Commission decision and its registration in the dataset.
• Some historical decisions were mapped on older cadastral compilations, which may be less precise than the renovated cadastre.
• The dataset requires cross-validation with decision text and attached plans to limit misinterpretation risks.
