Publish Content

Publishes an sf or data.frame object to an ArcGIS Portal as a FeatureCollection.

Usage

add_item(
  x,
  title,
  description = "",
  tags = character(0),
  snippet = "",
  categories = character(0),
  async = FALSE,
  type = "Feature Service",
  token = arc_token()
)

publish_item(
  item_id,
  publish_params = .publish_params(),
  file_type = "featureCollection",
  token = arc_token()
)

publish_layer(
  x,
  title,
  ...,
  publish_params = .publish_params(title, target_crs = sf::st_crs(x)),
  token = arc_token()
)

.publish_params(
  name = NULL,
  description = NULL,
  copyright = NULL,
  target_crs = 3857,
  max_record_count = 2000L
)

Arguments

x

an object of class data.frame. This can be an sf object or tibble or any other subclass of data.frame.

title

A user-friendly string title for the layer that can be used in a table of contents.

description

a length 1 character vector containing the description of the item that is being added. Note that the value cannot be larger than 64kb.

tags

a character vector of tags to add to the item.

snippet

a length 1 character vector with no more than 2048 characters.

categories

a character vector of the categories of the item.

async

default FALSE. Cannot be changed at this time.

type

default "Feature Service". Must not be changed at this time.

token

an httr2_token as created by auth_code() or similar

item_id

the ID of the item to be published.

publish_params

a list of named values of the publishParameters. Must match the values in the /publish endpoint documentation.

file_type

default "featureCollection". Cannot be changed.

...

arguments passed into add_item().

name

a scalar character of the name of the layer. Must be unique.

copyright

an optional character scalar containing copyright text to add to the published Feature Service.

target_crs

the CRS of the Feature Service to be created. By default, EPSG:3857.

max_record_count

the maximum number of records that can be returned from the created Feature Service.

Value

A named list containing the url of the newly published service.

Details

[Experimental]

  • add_item() takes a data.frame like object and uploads it as an item in your portal.

  • publish_item() takes an ID of an item in your portal and publishes it as a feature service.

  • publish_layer() is a high-level wrapper that first adds an object as an item in your portal and subsequently publishes it for you.

  • .publish_params() is a utility function to specify optional publish parameters such as copyright text, and the spatial reference of the published feature collection.

Note that there is only support for feature services meaning that only tables and feature layers can be made by these functions.

Publish Parameters

When publishing an item to a portal, a number of publish parameters can be provided. Most importantly is the targetSR which will be the CRS of the hosted feature service. By default this is EPSG:3857.

publish_layer() will use the CRS of the input object, x, by default. If publishing content in two steps with add_item() and publish_item(), use .publish_params() to craft your publish parameters. Ensure that the CRS provided to target_crs matches that of the item you added with add_item().

Examples

if (FALSE) {
  nc <- sf::st_read(system.file("shape/nc.shp", package = "sf"))
  x <- nc[1:5, 13]

  token <- auth_code()
  set_arc_token(token)

  publish_res <- publish_layer(
    x, "North Carolina SIDS sample"
  )
}
