Retrieve feature layer from ArcGIS REST service getFeatureLayer is used by writeLayer to write feature layers to local files

Usage

getFeatureLayer(url, bbox = NULL)

Arguments

url

URL of the layer REST service, ending with "/query". Example: https://geopub.epa.gov/arcgis/rest/services/EMEF/Tribal/MapServer/2/query (American Indian Reservations)

ArcGIS feature layer

Examples

if (FALSE) { # \dontrun{
# Load example dataset
data(Data_Nutrients_UT)
# Get the bounding box of the data
bbox <- sf::st_bbox(
  c(
    xmin = min(Data_Nutrients_UT$TADA.LongitudeMeasure),
    ymin = min(Data_Nutrients_UT$TADA.LatitudeMeasure),
    xmax = max(Data_Nutrients_UT$TADA.LongitudeMeasure),
    ymax = max(Data_Nutrients_UT$TADA.LatitudeMeasure)
  ),
  crs = sf::st_crs(Data_Nutrients_UT)
)
# Get the American Indian Reservations feature layer,
# filtered by the bounding box for the Data_Nutrients_UT example dataset
getFeatureLayer("https://geopub.epa.gov/arcgis/rest/services/EMEF/Tribal/MapServer/2/query", bbox)
} # }
