Distance to Shore [NM]

Geodesic distance from grid cell center to nearest shoreline

Description

Geodesic distance from each grid cell center to the nearest shoreline point, calculated using the Global Self-consistent Hierarchical High-resolution Geography (GSHHG) shoreline database [@gshhg_dataset] and reported in nautical miles (NM). This metric serves as a practical siting constraint that affects cable cost and grid connection feasibility.

Equation

\[ d = \text{haversine}(\text{cell center}, \text{nearest shoreline point}) \]

Where:

  • \(d\), geodesic distance calculated using GSHHG shoreline database \([\text{NM}]\)
  • \(1 \text{ NM} = 1.852 \text{ km}\)
