Add a WFS layer — add_wfs • geolibre

The GetFeature response is fetched and inlined into the project, so the endpoint must be able to return GeoJSON. This function contacts the service when called.

Usage

add_wfs(
  map,
  endpoint,
  type_name,
  name = "WFS Layer",
  version = "2.0.0",
  output_format = "application/json",
  srs_name = "EPSG:4326",
  max_features = 1000,
  style = list(),
  visible = TRUE,
  opacity = 1,
  ...
)

Arguments

map: A GeoLibre widget.
endpoint: WFS service endpoint.
type_name: WFS feature type name, for example "topp:states".
name: Layer name.
version: WFS protocol version, for example "2.0.0" or "1.1.0".
output_format: Requested output format; must yield GeoJSON.
srs_name: Spatial reference of the response.
max_features: Cap on the number of returned features, since the response is inlined. Pass NULL to request every feature.
style: Named list of GeoLibre style overrides such as fillColor, strokeColor, and strokeWidth.
visible: Whether the layer is initially visible.
opacity: Layer opacity from zero to one.
...: Additional style overrides given as named arguments, merged into style. add_geojson(map, data, fillColor = "red") and add_geojson(map, data, style = list(fillColor = "red")) are equivalent.

Value

The modified widget.

Examples

if (FALSE) { # \dontrun{
geolibre() |>
  add_wfs("https://ahocevar.com/geoserver/wfs", type_name = "topp:states")
} # }
