Harmonize plot data for EUNIS classification

Prepares vegetation plot header data for EUNIS habitat classification. Converts coordinates to EPSG:25832, assigns WWF ecoregions and country identifiers, optionally computes coast/dune flags, and optionally checks and harmonizes species taxonomy.

Use [resy_check_eunis()] first to verify that the input data meets all requirements before running this function.

Usage

resy_harmonize_eunis(
  data,
  source_crs = NULL,
  run_taxonomy = FALSE,
  species_data = NULL,
  parsed = NULL,
  run_coast_dunes = FALSE,
  coast_buffer = 5000
)

Arguments

data

A data frame or `sf` object containing plot data. If not an `sf` object, columns `Longitude` and `Latitude` must be present.

source_crs

Integer EPSG code of the input CRS. Required when `data` is a plain data frame; ignored when `data` is already an `sf` object.

run_taxonomy

Logical; if `TRUE`, runs [resy_check_taxonomy()] on `species_data`.

species_data

A data frame with a column `species`. Required when `run_taxonomy = TRUE`.

parsed

A `resy_parsed_expert` object from [resy_load_expert()]. Required when `run_taxonomy = TRUE`.

run_coast_dunes

Logical; if `TRUE`, assigns `Coast_EEA` and `Dunes_Bohn` flags via spatial intersection.

coast_buffer

Numeric buffer in metres for coastline proximity (default 5000).

Value

A named list:

`sites`

Data frame of harmonised plot data, geometry dropped, WGS84 `Longitude` and `Latitude` added.

`species_checked`

Output from [resy_check_taxonomy()] when `run_taxonomy = TRUE`, otherwise `NULL`.
