Greater Toronto Area 5-Meter Resolution Elevation Model

Greater Toronto Area digital elevation model data is organized into 20km by 20km tiles with a 5-meter spatial resolution. The dataset was produced by the Government of Ontario for pre-engineering survey, design, and planimetric mapping. Official metadata indicates a 2002 collection date, though the platform record was updated in March 2026.

Use Cases

• Generate slope and aspect maps from the 5-meter resolution elevation data for hydrological modeling.
• Perform line-of-sight analysis for telecommunications tower placement using the high-accuracy elevation model.
• Create contour lines and 3D terrain visualizations for urban planning applications within the 20km tile grid.
• Integrate elevation data with other geospatial layers for pre-engineering survey and design workflows.

Strengths

• High 5-meter spatial resolution suitable for detailed analysis.
• Data organized into standardized 20km by 20km tiles for manageable processing.

Limitations

• Original data collection date is 2002, making it potentially outdated for current terrain features.
• Specific row count, total area coverage, and vertical accuracy metrics are unavailable.
