Sidewalk Surface Polygons for Saint-Hyacinthe with Installation Year and Dimensions

Polygons and surfaces representing the extent of sidewalks on the territory of the city of Saint-Hyacinthe. The data is a technical drawing layer created by civil engineering technicians using computer-aided design, sourced from the Government and Municipalities of Québec via Open Canada. It was last updated on 2026-04-22.

Use Cases

• Calculate total sidewalk area and coverage based on the AREA attribute.
• Assess sidewalk material types and installation years for maintenance planning based on COATING and ANNEE_INSTALL.
• Analyze sidewalk dimensions for accessibility compliance based on LENGTH and WIDTH attributes.
• Map sidewalk locations and connectivity using the geospatial polygons and location attributes.

Strengths

• Includes detailed geometric attributes like LENGTH, WIDTH, and AREA for quantitative analysis.
• Attributes such as COATING and ANNEE_INSTALL provide material and temporal context for each feature.
• Data is provided in geospatial formats (GEOJSON, ESRI REST) suitable for GIS applications.
• Has a clear license (CC-BY-4.0) permitting reuse and modification.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes it is a technical drawing layer that does not represent the pedestrian network, limiting its use for connectivity analysis.
