In lakefetch: Calculate Fetch and Wave Exposure for Lake Sampling Points

Create Ray Geometries for Map Visualization

Description

Create line geometries representing fetch rays from each site. Useful for detailed visualization of the ray-casting results.

Usage

create_ray_geometries(fetch_data)

Arguments

fetch_data

Results from fetch_calculate

Value

An sf object with ray line geometries

Examples

csv_path <- system.file("extdata", "sample_sites.csv", package = "lakefetch")
sites <- load_sites(csv_path)
lake <- get_lake_boundary(sites)
results <- fetch_calculate(sites, lake)
rays <- create_ray_geometries(results)

# Plot rays for a specific site
site_name <- results$results$Site[1]
site_rays <- rays[rays$Site == site_name, ]
ggplot2::ggplot() + ggplot2::geom_sf(data = site_rays, ggplot2::aes(color = Distance))
