Description

Use this function to extract the unique location coordinates and names from a table or to create a blank template to manually fill.

Usage

template_geographic_coverage(
  path,
  data.path = path,
  data.table,
  lat.col,
  lon.col,
  site.col,
  empty = FALSE,
  write.file = TRUE,
  x = NULL
)

Arguments

path	(character) Path to the metadata template directory.
data.path	(character) Path to the data directory.
data.table	(character) Table name containing geographic coordinates.
lat.col	(character) Column name containing latitude coordinates in decimal degrees, where latitudes south of the equator are negative.
lon.col	(character) Column name containing longitude coordinates in decimal degrees, where longitudes west of the prime meridian are negative.
site.col	(character) Column name containing site names.
empty	(logical) Whether to write an empty template file.
write.file	(logical; optional) Whether to write the template file.
x	(named list; optional) Alternative input to template_geographical_coverage(). Use template_arguments() to create x.

Value

geographical_coverage

Columns: geographicDescription: Brief description of location. northBoundingCoordinate: North coordinate southBoundingCoordinate: South coordinate eastBoundingCoordinate: East coordinate westBoundingCoordinate: West coordinate

  data.table = "nitrogen.csv",
  site.col = "site_name",
  lat.col = "site_lat",
  lon.col = "site_lon")
  
# For returning an empty template to be filled manually
