Quebec Vector Grid System for Spatial Data Integration, 2026 Update

Quebec's vector grid system provides a spatial and statistical infrastructure for integrating environmental and socio-economic data. The Institut de la Statistique du Québec (ISQ) maintains this system, which includes a 1 km² grid covering all of Quebec and a 50 m side grid for areas south of the 52nd parallel. The dataset was last updated in April 2026.

Use Cases

• Integrating human population and economic data within a consistent spatial framework based on the described grid system.
• Analyzing land cover changes over time by linking data from different decades within the same grid cells.
• Compiling statistics for different territorial divisions using the grid's fixed geographic references to monitor changes over time.

Strengths

• Includes two nested vector grids at 1 km² and 50 m side resolutions, designed for multi-scale analysis.
• Forms the official geographic infrastructure for the Southern Quebec Land Accounts, promoting provincial data consistency.
• License is CC-BY-4.0, allowing for broad reuse with attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description mentions an update in 2026, but the underlying land cover data referenced spans the 1990s to 2010s.
