Building Footprints in Laval with Construction and Survey Methods

Building footprints for the territory of Laval, Quebec, produced by the City of Laval. The dataset includes fields for building type, name, release date, and the digitization method used for each structure. Data is provided in multiple geospatial formats including SHP, GEOJSON, and KML.

Use Cases

• Classify building TYPE (e.g., primary, agricultural, station) across the municipal territory for urban planning.
• Analyze DATE_RELEASE to track geometric modifications or new construction over time.
• Assess the distribution of data collection methods using the TYPE_RELEVE field (e.g., Lidar, photogrammetry, field survey).
• Map named structures by filtering on the BUILDING_NAME field for landmark identification.

Strengths

• Includes a DATE_RELEASE field for tracking data creation or modification.
• Documents the digitization method (TYPE_RELEVE) for each feature, detailing sources like Lidar or photogrammetry.
• Available in multiple standard geospatial formats (SHP, GEOJSON, CSV, KML, HTML).

Limitations

• Unknown row count and dataset size limits assessment of coverage and detail.
• The description notes that DATE_RELEASE and TYPE_RELEVE fields may contain null values where information is unavailable.
• Lack of sample data prevents verification of field completeness and data structure.
