Summarize Acres of Overlay Features within HUC12 Watersheds

Usage

summarize_acres_by_huc12(
  huc12,
  overlay,
  huc_id_col = "huc12",
  group_vars = NULL
)

Arguments

huc12: An sf object representing HUC12 watersheds
overlay: An sf object representing layers to be summarized (e.g., wetlands) if overlay is polygon it calculates acres, if point it just returns a count
huc_id_col: The name of the column identifying each HUC12 unit (default: "huc12")
group_vars: Optional character vector of additional grouping columns from the overlay layer (e.g., c("wetland_type"))

Value

A data frame summarizing acres by HUC12 and optional groupings

Examples

if (FALSE) { # \dontrun{

huc12 <- get_geoserver_layer("all_columbia_huc_12s")
geohazards <- get_geoserver_layer("columbia-geologic-hazard")

geohaz_acres <- summarize_acres_by_huc12(huc12 = huc12,
overlay = geohazards, group_vars = "forpehrtdc")
} # }
