Shawinigan Heritage Building Inventory with Polygons and Attributes

Heritage buildings - Ville de Shawinigan is a polygonal geospatial inventory of built heritage structures within the city of Shawinigan. The inventory was conducted by the firm PatriArch in 2010, 2014, and 2021, with data provided by the Government and Municipalities of Québec. It includes attributes like building name, description, classification, and links to photographic documentation.

Use Cases

• Map and analyze the spatial distribution of heritage buildings using the polygonal `st_area (shape)` and `st_length (shape)` attributes.
• Classify building types or heritage significance based on the `class` and `categorization_statement` text fields.
• Link building records to external photographic documentation via the `photo_link` or `jpg_link` URL columns for visual analysis.
• Filter and study inventory records based on the survey period using the `inventory_year` field.
• Generate descriptive reports for individual heritage sites by combining the `buildingname`, `description`, and `report` text attributes.

Strengths

• Inventory conducted across three distinct survey years (2010, 2014, 2021), providing temporal snapshots.
• Includes 12 distinct attribute columns covering identification, description, classification, geometry, and media links.
• Data is provided under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• The total number of building records (rows) is unknown, making it difficult to assess dataset scale.
• Data collection method suggests potential for geographic bias, limited strictly to the territory of Shawinigan.
• Reliance on automated translation for metadata may introduce inaccuracies in field descriptions.
