Canopy 2020: Vegetation Cover Map of Quebec City from Satellite and Lidar

July 2020 vegetation canopy data for Quebec City, derived from automated classification of World-View-3 and Pléiades satellite imagery with 31 cm resolution, supplemented by a 2017 Lidar survey. The dataset represents the ground projection of tree crowns as visible from the sky. It is provided by the Government and Municipalities of Québec under a CC-BY-4.0 license.

Use Cases

• Assess urban tree canopy coverage and distribution based on high-resolution satellite imagery.
• Model ecosystem services like carbon sequestration and stormwater runoff mitigation based on vegetation density.
• Support municipal planning for green space management and climate adaptation strategies based on canopy extent.
• Validate or update land cover classifications for the region based on combined satellite and Lidar data sources.

Strengths

• Uses very high-resolution satellite imagery with a spatial resolution of 31 cm.
• Combines data from two distinct sources: satellite imagery from July 2020 and a Lidar survey from 2017.
• Released under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The data fusion involves sources from different years (2017 Lidar and 2020 imagery), which may introduce temporal inconsistencies.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale projects.
