Chena River Substrate Habitat Map Derived from Side-Scan Sonar

2021 and 2022 side-scan sonar scans of the lower Chena River were processed to remove the water column and classify substrate types. The resulting file geodatabase contains substrate imagery and mosaiced imagery. The dataset was produced by the Department of the Interior following established sonar processing protocols.

Use Cases

• Map river substrate types based on processed side-scan sonar imagery
• Analyze habitat suitability for Chinook salmon based on substrate classification
• Create substrate-specific shapefiles for habitat management planning

Strengths

• Data collection spans two years (2021 and 2022)
• Processed using established protocols from the Florida Fish and Wildlife Conservation Commission
• Focuses on a specific geographic area (lower Chena River)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
