Ontario Bathymetric Depth Measurements

Bathymetry points contain water depth measurements collected across bodies of water in Ontario. Data originates from surveys conducted by the Government of Ontario using echo-sounders with GPS positioning and bathymetric LiDAR. The dataset was last updated in March 2026.

Use Cases

• Model lakebed topography from point-cloud depth data for flood risk assessment.
• Analyze water depth variations using GPS-positioned measurements for nautical chart updates.
• Train models to predict sediment distribution by correlating depth points with survey method metadata.
• Integrate bathymetric point data with surface elevation models for 3D watershed analysis.

Strengths

• Data is sourced from authoritative government surveys using echo-sounders and LiDAR.
• Includes a linked Bathymetry Index detailing the survey method for each body of water.
• Maintained with a recent update in March 2026.

Limitations

• Unknown total number of measurement points and spatial resolution.
• Specific geographic coverage within Ontario and temporal range of surveys are not provided.
• Data format details and column structure are unspecified.
