Vineyard Cold-Air Pooling Susceptibility from UAV Terrain Models

A UAV-derived Digital Terrain Model for the Osoyoos Larose Vineyard in British Columbia's Okanagan Valley. The dataset maps terrain-driven cold-air pooling susceptibility using Topographic Position Index and flow accumulation analysis. It was created by Clarissa Gutierrez and last updated in May 2026.

Use Cases

• Identifying frost-prone zones within a vineyard based on terrain-driven cold-air pooling susceptibility.
• Guiding frost mitigation decisions based on the spatial distribution of Strong and Moderate susceptibility areas.
• Validating and adapting the described UAV-DTM analysis framework for other viticultural landscapes.

Strengths

• Analysis covers 18 vineyard blocks, providing a vineyard-scale assessment.
• Identified 2,042 square meters of combined Strong and Moderate cold-air pooling susceptibility.
• Focuses on a specific, high-value agricultural application for frost management.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Geographic coverage is limited to a single vineyard in the Okanagan Valley.
