addEsriFeatureLayer: Adds an ArcGIS Feature Layer.

In leaflet.esri: 'ESRI' Bindings for the 'leaflet' Package

Description

FeatureLayer is used to visualize, style, query and edit vector geographic data hosted in both ArcGIS Online and published using ArcGIS Server. Copyright text from the service is added to map attribution automatically.

Usage

addEsriFeatureLayer(map, url, useServiceSymbology = FALSE,
  options = featureLayerOptions(), layerId = NULL, group = NULL,
  markerType = NULL, markerIcons = NULL, markerIconProperty = NULL,
  markerOptions = leaflet::markerOptions(), clusterOptions = NULL,
  clusterId = NULL, labelProperty = NULL,
  labelOptions = leaflet::labelOptions(), popupProperty = NULL,
  popupOptions = leaflet::popupOptions(), stroke = TRUE, color = "#03F",
  weight = 5, opacity = 0.5, fill = TRUE, fillColor = color,
  fillOpacity = 0.2, dashArray = NULL, smoothFactor = 1, noClip = FALSE,
  pathOptions = leaflet::pathOptions(), highlightOptions = NULL,
  fitBounds = FALSE)

Arguments

map	The leaflet map
url	url of the FeatureService or MapService.
useServiceSymbology	whether to use the symbology set when a service was published.
options	options for the featurelayer
layerId	A unique ID for the layer.
group	The name of the group this layer should be added to. the same parameter under addTiles)
markerType	The type of marker. either "marker" or "circleMarker"
markerIcons	Icons for Marker.
markerIconProperty	The property of the feature to use for marker icon. Can be a JS function which accepts a feature and returns an index of markerIcons. In either case the result must be one of the indexes of markerIcons.
markerOptions	The options for markers Can be a single marker using makeIcon or a list of markers using iconList
clusterOptions	if not NULL, markers will be clustered using Leaflet.markercluster; you can use markerClusterOptions() to specify marker cluster options
clusterId	the id for the marker cluster layer
labelProperty	The property to use for the label. You can also pass in a JS function that takes in a feature and returns a text/HTML content.
labelOptions	A Vector of labelOptions to provide label options for each label. Default NULL
popupProperty	The property to use for popup content You can also pass in a JS function that takes in a feature and returns a text/HTML content.
popupOptions	A Vector of popupOptions to provide popups
stroke	whether to draw stroke along the path (e.g. the borders of polygons or circles)
color	stroke color
weight	stroke width in pixels
opacity	stroke opacity (or layer opacity for tile layers)
fill	whether to fill the path with color (e.g. filling on polygons or circles)
fillColor	fill color
fillOpacity	fill opacity
dashArray	a string that defines the stroke dash pattern
smoothFactor	how much to simplify the polyline on each zoom level (more means better performance and less accurate representation)
noClip	whether to disable polyline clipping
pathOptions	Options for shapes
highlightOptions	Options for highlighting the shape on mouse over. you can use highlightOptions() to specify highlight
fitBounds	Whether to set the maps bounds to fit the data in the featureLayer options

Examples

leaflet() %>%
  addEsriBasemapLayer(esriBasemapLayers$Streets) %>%
  setView(-122.667, 45.526, 13) %>%
  addEsriFeatureLayer(
    url = paste0("https://services.arcgis.com/rOo16HdIMeOBI4Mb/arcgis/rest/services/",
                 "Heritage_Trees_Portland/FeatureServer/0"),
    useServiceSymbology = TRUE,
    labelProperty = "COMMON_NAM", labelOptions = labelOptions(textsize = "12px"),
  popupProperty = JS(paste0(
    "function(feature) {",
    "  return L.Util.template(",
    "    \"<h3>{COMMON_NAM}</h3><hr />",
    "      <p>This tree is located at {ADDRESS} and its scientific name is {SCIENTIFIC}.</p>",
    "    \",",
    "    feature.properties",
    "  );",
    "}"
  )))
