%description
Calculates fetch (open water distance) and wave exposure metrics for lake
sampling points. Downloads lake boundaries from 'OpenStreetMap',
calculates directional fetch using a ray-casting approach, and optionally
integrates National Hydrography Dataset ('NHD') data
<https://www.usgs.gov/national-hydrography> for hydrological context
including outlet and inlet locations. Can estimate lake depth from surface
area using empirical relationships, and integrate historical weather data
for cumulative wave energy calculations. Includes an optional interactive
'shiny' application for visualization.
