Level Curves from 2024 LiDAR Survey with 1-Meter Equidistance

Level curves with a 1-meter equidistance derived from a LiDAR survey conducted in 2024. The dataset includes attributes for a unique ID, curve subtype, and elevation value in meters. It is provided by the Government and Municipalities of Québec and was last updated in March 2026.

Use Cases

• Generate high-resolution terrain models based on the 1-meter equidistance level curves.
• Analyze elevation changes and slope for hydrological or erosion studies based on the elevation values.
• Create training data for computer vision models that interpret topographic features from the level curve geometry.
• Integrate elevation data into geospatial planning or simulation tools based on the provided attributes.

Strengths

• Derived from a 2024 LiDAR survey, suggesting recent and potentially high-accuracy source data.
• Includes a unique ID and elevation value attributes for each level curve.
• Available under a permissive CC-BY-4.0 license.
• Offered in multiple geospatial formats including KML, GeoJSON, and ESRI REST.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description was translated using an automated tool, which may introduce ambiguity.
