Communicating with a WFS service in a web browser—ArcGIS Server

The online resource of each operation supported by a compliant WFS server is an HTTP uniform resource locator (URL), so a WFS service can be considered as a Representational State Transfer (REST) service. Through URL parameters, you can use these operations to obtain service metadata, feature type information, and GML-encoded features from the WFS service. These operations and parameters are detailed in the OGC WFS specification.

Types of clients

WFS services can be used in any client that supports WFS. Most often, a web browser is the basic client of a WFS service. WFS requests can be issued through HTTP, and the responses or exceptions are returned through the browser. All WFS services support three primary operations: GetCapabilities, DescribeFeatureType, and GetFeature. The ArcGIS Server implementation of WFS 2.0.0 defines additional operations: GetFeatureByID, ListStoredQueries, and DescribeStoredQueries.

There are many third-party clients available for consuming WFS services. To consume WFS services, the client must support WFS 1.0.0, 1.1.0, or 2.0.0 and the Simple Features Profile of GML. Additionally, ArcGIS Pro can work with WFS services. For help with WFS services in ArcGIS Pro, see Add WFS services.

WFS URL structure

To connect to the service, you need to know the URL, which follows this pattern:

http://gisserver.domain.com:6080/arcgis/services/<folder name (if applicable)>/<service name>/MapServer/WFSServer?

The server name is the name of your web server machine.
The port number is the port your web server machine uses to communicate with other computers.

For example, if you enable the WFS capability on the map service WFSDemoService in a folder named DemoFolder on server gisserver.domain.com running on port 6080, the GetCapabilities URL will be as follows:

http://gisserver.domain.com:6080/arcgis/services/DemoFolder/WFSDemoService/MapServer/WFSServer?service=WFS&request=GetCapabilities

Using filters

The Filter parameter can be used in WFS requests to obtain specific features in a WFS service. The benefit of the Filter parameter is that it’s part of the standard keyword-value pair encoding defined in section 9.5 of the WFS 1.1 Implementation Specification and can be appended at the end of HTTP requests. WFS 1.0.0 and 1.1.0 services use the OGC OpenGIS Filter Encoding Implementation Specification (FE) version 1.1.0. WFS 2.0.0 uses version 2.0.0 of the filter specification.

The following table lists the filters you can apply:


Geometry	Spatial	Logical	Comparison	Sort
Envelope	BBOX	And	EqualTo	SortBy*
Point	Equals	Or	NotEqualTo
MultiPoint	Disjoint	Not	LessThan
LineString	Intersects		GreaterThan
Polygon	Crosses		LessThanOrEqualTo
	Touches		GreaterThanOrEqualTo
	Within		Like
	Contains		Between
	Overlaps		NullCheck

Note:

*The SortBy filter can only be applied to WFS services based on data stored in an enterprise geodatabase.

For example, if you create a FeatureType named blockgroups in a WFS service, you can request blockgroup features within extent -122.423192682619, 37.7877919206256, -122.421377806544, 37.7893634225143 by sending the following GetFeature request:

http://gisserver.domain.com:6080/arcgis/services/playground/sanfrancisco_wfs/MapServer/WFSServer?service=WFS&request=GetFeature&version=1.1.0&typename=esri:blockgroups&Filter=<ogc:Filter><ogc:BBOX><ogc:PropertyName>Shape</ogc:PropertyName><gml:Box srsName="urn:x-ogc:def:crs:EPSG:4326"><gml:coordinates>37.7877919206256,-122.423192682619 37.7893634225143,-122.421377806544</gml:coordinates></gml:Box></ogc:BBOX></ogc:Filter>

If you want to request a blockgroups feature that contains a specific point feature, such as 122.431577, 37.749936, you can send the following GetFeature request:

http://gisserver.domain.com:6080/arcgis/services/playground/sanfrancisco_wfs/MapServer/WFSServer?service=WFS&request=GetFeature&version=1.1.0&typename=esri:blockgroups&Filter=<ogc:Filter><ogc:Contains><ogc:PropertyName>Shape</ogc:PropertyName><gml:Point srsName="urn:x-ogc:def:crs:EPSG:4326"><gml:pos srsName="urn:x-ogc:def:crs:EPSG:4326">37.749936 -122.431577</gml:pos></gml:Point></ogc:Contains></ogc:Filter>

Note:

WFS requires involved name space prefixes to be present in the filter XML string. Additionally, to avoid incorrect conversions being completed by web browsers or web servers, the URL encodes the filter XML string before sending it to the server.

Consuming a WFS 1.0.0 or 1.1.0 service in a web browser

The following examples use URL parameters to communicate with WFS and WFS-T 1.0.0 and 1.1.0 services in a web browser. To learn how to use WFS 2.0.0 operations in a web browser, see the Consuming a WFS 2.0 service in a web browser section below.

GetCapabilities

This request returns all feature types and functionality available through the service in GML format. To use the GetCapabilities operation, copy and paste the WFS service URL into the address bar, and add ?service=WFS&request=getcapabilities to the end of the URL.

URL example: http://gisserver.domain.com:6080/arcgis/services/wfs_services/enterprise_wfs/MapServer/WFSServer?service=WFS&request=GetCapabilities

DescribeFeatureType

This request describes the field information about one or more features in the WFS service. This includes the field names, field types, allowed minimum and maximum field values, and any other constraints set on a field of the feature classes or tables.

To use the DescribeFeatureType operation, copy and paste the WFS URL into the address bar and add ?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&VERSION=1.1.0 to the end of the URL. This returns all the field information about each of the feature types and tables available in the feature service.

URL example: http://gisserver.domain.com:6080/arcgis/services/wfs_services/enterprise_wfs/MapServer/WFSServer?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&VERSION=1.1.0

Adding filters

You can also specify a single feature class or table that you want the field information for by appending the following request to the end of the URL with the name of the feature type or table:

?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&typeName=<enter feature type here>

In the following example, the DescribeFeatureType request is used to identify the field information for the feature type named continent:

URL example: http://gisserver.domain.com:6080/arcgis/services/wfs_services/enterprise_wfs/MapServer/WFSServer?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TypeName=continent

GetFeature

This request returns information about specific feature types available through the WFS service.

To use the GetFeature operation in a web browser, copy and paste the WFS URL into the address bar and add ?service=WFS&version=1.1.0&request=GetFeature&typeName=<enter feature type here> to the end of the URL. This returns all the attribute and geometry information about each feature or row in the feature type.

URL example: http://gisserver.domain.com:6080/arcgis/services/wfs_services/enterprise_wfs/MapServer/WFSServer?service=WFS&version=1.1.0&request=GetFeature&typeName=cities

Adding filters

You can also add filters in the request to refine the returned results. For example, you can request all the cities within a specified coordinate range. In the following example, three cities are located within a specified coordinate range:

URL example: http://gisserver.domain.com:6080/arcgis/services/wfs_services/enterprise_wfs/MapServer/WFSServer?service=WFS&version=1.1.0&request=GetFeature&typeName=cities&BBOX=46.90,-76.21,42.12,-72.88

Insert

Insert is used to create new features in a single transaction request. By default, the initial state of a feature to be created is expressed using GML3 and must validate relative to a GML3 application schema generated by the DescribeFeatureType operation.

For example, the following POST sample inserts a point feature representing a city:

<wfs:Transaction xmlns:gml="http://www.opengis.net/gml" xmlns:wfs="http://www.opengis.net/wfs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:esri="http://www.esri.com" version = "1.1.0" service="WFS">>
  <wfs:Insert>
    <esri:Cities>
      <esri:NAME>Tofino</esri:NAME>
      <esri:CAPITAL>N</esri:CAPITAL>
      <esri:PROV_NAME>British Columbia</esri:PROV_NAME>
      <esri:POPULATION>12345</esri:POPULATION>
      <esri:RepRowID>1000</esri:RepRowID>
      <esri:Shape>
        <gml:Point>
          <gml:coordinates>59.163182034 -133.844892907</gml:coordinates>
        </gml:Point>
      </esri:Shape>
    </esri:Cities>
  </wfs:Insert>
</wfs:Transaction>

Update

Update is used to update a feature or features (of a single type) in a single transaction request.

The <Update> element contains one or more <Property> elements that specify the name and replacement value for a property that belongs to the feature type specified using the mandatory typeName attribute. A <Property> element contains a <Name> element that contains the name of the feature property to be modified and an optional <Value> element that contains the replacement value for the named feature property. The omission of the <Value> element means that the property should be assigned a NULL value. In the event that the property is not nullable, the WFS must raise an exception indicating that the NULL value is not allowed.

For example, the following POST sample updates a point feature in a dataset named cities:

<wfs:Transaction xmlns:gml="http://www.opengis.net/gml" xmlns:wfs="http://www.opengis.net/wfs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ogc="http://www.opengis.net/ogc" xmlns:esri="http://www.esri.com" version = "1.1.0" service="WFS">
  <wfs:Update typeName="esri:cities">
    <wfs:Property>
    <wfs:Name>POPULATION</wfs:Name>
    <wfs:Value>300000</wfs:Value>
  </wfs:Property>
  <ogc:Filter>
    <ogc:PropertyIsEqualTo>
      <ogc:PropertyName>NAME</ogc:PropertyName>
      <ogc:Literal>Halifax</ogc:Literal>
    </ogc:PropertyIsEqualTo>
  </ogc:Filter>
  </wfs:Update>
</wfs:Transaction>

Delete

Delete is used to delete one or more features (of a single type) in a single transaction request. Delete is defined using the <Filter> element. In the event that the <Filter> element does not identify any feature instances to delete, the delete request is ignored.

For example, the following POST sample deletes two features in a dataset named cities:

<wfs:Transaction xmlns:gml="http://www.opengis.net/gml" xmlns:wfs="http://www.opengis.net/wfs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ogc="http://www.opengis.net/ogc" xmlns:esri="http://www.esri.com" version = "2.0.0" service="WFS">
  <wfs:Delete typeName="esri:cities">
    <ogc:Filter xmlns:ogc='http://www.opengis.net/ogc'>
        <ogc:PropertyIsEqualTo>
          <ogc:PropertyName>NAME</ogc:PropertyName>
          <ogc:Literal>Churchill</ogc:Literal>
        </ogc:PropertyIsEqualTo>
    </ogc:Filter>
  </wfs:Delete>
  <wfs:Delete typeName="esri:cities">
    <ogc:Filter xmlns:ogc='http://www.opengis.net/ogc'>
        <ogc:PropertyIsEqualTo>
          <ogc:PropertyName>NAME</ogc:PropertyName>
          <ogc:Literal>Montreal</ogc:Literal>
        </ogc:PropertyIsEqualTo>
    </ogc:Filter>
  </wfs:Delete>
</wfs:Transaction>

Consuming a WFS 2.0 service in a web browser

The ArcGIS Server implementation of the WFS 2.0.0 specification addresses the required features of the basic WFS profile, as stated in the WFS 2.0 specification. This includes the GetCapabilities, DescribeFeatureType, and GetFeature operations (described above). The WFS 2.0 implementation also supports transactions, stored queries, and response paging, which are not part of the basic WFS profile.

Transactions

The transaction operation is used to describe data transformation operations applied to feature instances in a WFS service. Using the transaction operation, clients can create, modify, replace, and delete features in the WFS. When the transaction completes, the WFS generates an XML response document indicating the completion status of the operation.

Stored queries

Stored queries allow complex filter queries to be stored by WFS 2.0 and run using a basic request. To achieve the same result with WFS 1.0.0 or 1.1.0, you would have to write a filter using a filter encoding specification and append it to the WFS URL. Configuring stored queries gives you the following benefits that broaden the use of WFS 2.0 in applications:

Complex queries can be streamlined so they can be run as HTTP GET requests.
Stored queries can reduce costs for development of applications since they can be configured to support specific queries rather than complex ad hoc queries and XPath expressions.
RESTful interfaces can be established on top of the WFS alongside HTTP GET/POST and SOAP to enable the WFS to be used within lightweight client applications.

The following operations are available to support stored queries: GetFeatureByID, ListStoredQueries, and DescribeStoredQueries (described below).

Creating a stored query file

A stored query file is an XML file that maintains a list of publisher-authored stored queries relevant for a particular service. To use stored queries with WFS 2.0, create a stored query file and configure the service to reference the URL of your stored queries file.

The following example stored query file works with the SampleWorldCities map service included with ArcGIS Server. You can use this example and modify the file to work with a different WFS service.

GetFeatureByID

The GetFeatureByID operation takes a single argument, named id that is of type xsd:string, and returns a single feature whose identifier is equal to the specified value of the id argument.

The following URL example invokes the GetFeatureByID stored query to retrieve and display a single feature:

http://gisserver.domain.com/arcgis/services/SampleWorldCities/MapServer/WFSServer?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetFeature&STOREDQUERY_ID=urn:ogc:def:query:OGC-WFS::GetFeatureById&ID=Cities.1

ListStoredQueries

The ListStoredQueries operation lists the stored queries available on ArcGIS Server. The client can run one stored query at a time, for example:

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?request=ListStoredQueries&service=WFS&version=2.0.0

DescribeStoredQueries

The DescribeStoredQueries operation describes the stored queries available on ArcGIS Server. This operation is useful for WFS clients to interrogate the server, and to understand the nature of the stored query and the parameters that need to be sent to run the stored query.

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?request=DescribeStoredQueries&service=WFS&version=2.0.0

Running a stored query as part of a GetFeature request

The following is an example of an attribute request where a stored query (AttributeDemo) is called using the myrank=3 parameter:

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?service=WFS&version=2.0.0&REQUEST=GetFeature&typeName=cities&startIndex=0&count=5&STOREDQUERY_ID=urn:StoredQueries:AttributeDemo&myrank=3

The following is an example where a stored query (SpatialDemo) is called using the coordinates parameter to retrieve a list of U.S. cities that fall within a bounding box. Only the first two cities are returned from this list (note the use of startindex and count):

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?service=WFS&version=2.0.0&REQUEST=GetFeature&typeName=cities&startIndex=0&count=2&STOREDQUERY_ID=urn:StoredQueries:SpatialDemo&coordinates=0,-180%2090,0

The following is an example where a stored query (FunctionChar_Length) is called. The stored query on the server is written to filter out cities with name lengths greater than two characters:

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?service=WFS&version=2.0.0&REQUEST=GetFeature&typeName=Cities&STOREDQUERY_ID=urn:StoredQueries:FunctionCHAR_LENGTH

Response paging

Response paging allows a request to specify the start index of the feature to retrieve. Additionally, a count of the number of features to retrieve can be specified.

Using the SampleWorldCities map service installed with ArcGIS Server, the following query returns two cities (count=2), Brasilia and Goiania:

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?service=WFS&version=2.0.0&REQUEST=GetFeature&typeName=cities&startIndex=1&count=2

If you change the request and have the startindex begin at 2, the first city returned is Goiania. Since the count=2, two cities now return with the request: Goiania and Campo Grande.

http://gisserver.domain.com:6080/arcgis/services/SampleWorldCities/MapServer/WFSServer?service=WFS&version=2.0.0&REQUEST=GetFeature&typeName=cities&startIndex=2&count=2
