Connecticut Steep Slope Areas Derived from 2023 Lidar and Imagery

Connecticut's landscape is covered by this geospatial dataset identifying areas with significant slope gradients. It was derived from the 2023 Digital Elevation Model based on Spring 2023 imagery and lidar capture and is provided by the State of Connecticut. The data includes two feature layers for analysis at 10-foot and 2-foot pixel resolutions.

Use Cases

• Assess terrain steepness for land use planning based on slope percentage categories.
• Support environmental management decisions based on municipality and Council of Governments (COG) region attributes.
• Conduct risk assessment related to slope stability based on geographic slope data.
• Perform higher-resolution terrain studies using the 2-foot per pixel DEM layer.

Strengths

• Derived from a 2023 Digital Elevation Model, providing recent topographic data.
• Includes two resolution layers (10-foot and 2-foot per pixel) for different analysis scales.
• Attributes include slope percentage categories (Moderate, Steep, Very Steep), municipality, and COG region.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Update frequency is listed as 'none', suggesting it is a static snapshot.
• Column-level documentation beyond the three listed attributes is absent; field semantics must be inferred after download.
