Dynamic Shoreline Feature

Feature type for tide-dependent shoreline vectors, encoding shoreline type, water level at capture, tidal datum reference, sensor platform, and spatial/temporal uncertainty. Enables multi-temporal shoreline analysis and supports FMSDI Best Practice 3 (Mind the Gap) and Best Practice 1 (Unified Geospatial Reference). Derived from TCarta FMSDI demonstrator at Hurst Spit using Planet Labs NDWI and Capella SAR data.
