Ontario Building Landmarks As Geospatial Symbols

Ontario, Canada provides a dataset of buildings and structures represented as permanent landmark symbols. The Government of Ontario maintains this data, which requires GIS software for use and was last updated in March 2026. Symbolized features include buildings with no side exceeding 50 meters at 1:20,000 scale or 30 meters at 1:10,000 scale.

Use Cases

• Classify building symbols based on their scale representation (1:20,000 or 1:10,000) for cartographic styling.
• Filter landmark buildings using the size criteria (e.g., side length > 50m) for regional orientation point analysis.
• Integrate symbolized building geometries with other geospatial layers for urban infrastructure mapping.

Strengths

• Data is maintained by the authoritative Government of Ontario.
• Includes explicit cartographic rules for symbolization based on building side length and scale.

Limitations

• Specific row counts, geographic extent, and sample data are unavailable for assessment.
• Small structures under 50 square meters are generally excluded, introducing a size bias.
