Calgary Building Roof Outlines and Spatial Coordinates

Polygon features representing individual building roof outlines throughout the City of Calgary. The data includes spatial coordinates (X_COORD, Y_COORD), building codes (BLDG_CODE, BLDG_CODE_DESC), and geometry attributes (SHAPE__Area, SHAPE__Length). It is provided by data.calgary.ca and was last updated in April 2026.

Use Cases

• Calculate total roof area for solar potential analysis using the SHAPE__Area column.
• Analyze building density and spatial distribution across neighborhoods using X_COORD and Y_COORD.
• Classify building types for urban planning using the BLDG_CODE_DESC feature.
• Track changes in building footprints over time using the CREATE_DT_UTC and MOD_DT_UTC timestamps.
• Identify potentially obscured building outlines for 3D modeling or surveying using the OBSCURED flag.

Strengths

• Includes 10 specific columns detailing geometry, location, and metadata.
• Provides polygon geometry (multipolygon) for spatial analysis.
• Data is current, with a last updated date in April 2026.

Limitations

• Unknown total number of building records (rows).
• Geographic coverage is limited to the City of Calgary.
• Sample data is unavailable for preliminary inspection.
