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

Add Depth Information to Fetch Results

Description

Looks up or estimates depth for each lake in the fetch results and adds depth columns.

Usage

add_lake_depth(fetch_results, lakes, user_depths = NULL)

Arguments

fetch_results	sf object with fetch results
lakes	sf object with lake polygons
user_depths	Named vector of user-provided depths (names = lake IDs)

Value

fetch_results with added depth columns

Examples

data(adirondack_sites)
sites <- load_sites(adirondack_sites)
lake <- get_lake_boundary(sites)
results <- fetch_calculate(sites, lake)

# Add depth estimates
results$results <- add_lake_depth(results$results, results$lakes)

# Or provide known depths using an actual lake_osm_id from results
lake_id <- results$lakes$osm_id[1]
depths <- setNames(15.5, lake_id)
results$results <- add_lake_depth(results$results, results$lakes, user_depths = depths)
