Large Building Footprint Geospatial Data for Ontario

Geospatial data from the Government of Ontario provides extents for structures exceeding 50 meters at 1:20,000 scale or 30 meters at 1:10,000 scale. It includes building locations and outlines for smaller structures. The dataset was last updated in March 2026.

Use Cases

• Analyze urban density by calculating the area of recorded building extents.
• Identify large-scale infrastructure by filtering for structures with dimensions exceeding the 50-meter threshold.
• Integrate building location points with other geospatial layers for land-use planning.
• Study the distribution of small buildings using their recorded location coordinates.

Strengths

• Includes a defined scale-based classification for large structures (over 50m or 30m).
• Published by a government authority (Government of Ontario).
• Recently updated in March 2026.

Limitations

• Unknown total number of building records or spatial coverage completeness.
• Data granularity is limited for small buildings, which only have location points.
