Lawrence, Peter (2025) TAID: Tidally Adjusted Intertidal Digital Elevation Models.

This catalogue provides a comprehensive collection of raster (.tif) files delivering 1 meter resolution Digital Terrain Models (DTMs), tiled in 5 km grid cells within the British National Grid. These DTMs are a product of Version 1.0 of the Tidally Adjusted Intertidal Digital elevation models (TAID). These are developed to support a detailed, tidally referenced investigations of near shore processes and ecological phenome. A key feature of these models is tidal adjustment—elevation values in each raster are precisely referenced to a specific tidal datum. This adjustment accounts for spatial variations in tidal levels around the British coast and is critical for a wide range of coastal applications, including: Coastal Flood Modelling – Accurate simulation of inundation scenarios. Sea-Level Rise Impact Assessment – Improved precision in predicting future coastal changes. Nearshore Hydrological Processes – Enhanced understanding of coastal water dynamics. Species Distribution and Habitat Analysis – Informing ecological assessments in intertidal zones. These high-resolution DTMs could serve as a vital baseline for researchers, environmental managers, and planners engaged in UK coastal resilience, conservation, and sustainable development. Important Notes: These datasets are linked to the TAID v1.0 model release. The underlying methodology includes numerous tuning and hyper-parameters, and future model versions are expected as techniques and data sources evolve. This dataset is and should not be used for navigation. Users must consult the associated technical documentation, peer-reviewed manuscript and/or the corresponding author prior to application.
