WFS To Feature Class (Conversion)

Summary

Imports a feature type from a Web Feature Service (WFS) to a feature class in a geodatabase.

Usage

• Download features from a simple or complex WFS service.

• After setting the URL for the WFS server, all feature types published from the server will be listed. Examples can include WFS feature types for schools, roads, and parcels. One of these is then selected and an output location and name are specified.

• By default, all features from the WFS source are added to the feature class. The extent environment setting can be used to limit the features to only those that intersect a user-defined extent. You can also specify an output configuration keyword using the geodatabase settings section of the environment settings.

Parameters

Dialog

Label	Explanation	Data Type
WFS Server	The URL of the source WFS service (for example, http://sampleserver6.arcgisonline.com/arcgis/services/SampleWorldCities/MapServer/WFSServer?). If the input is a complex WFS service (Complex WFS service is checked), this can also be the path to the .xml file.	String
Select Feature Type to Extract	The name of the WFS layer to extract from the input WFS service.	String
Output Location	The location of the output feature class or geodatabase. If the input is a simple WFS, the output location can be a geodatabase or a feature dataset in a geodatabase. If the output location is a feature dataset, the coordinates will be converted from the source coordinate system to the coordinate system of the feature dataset. If the input is a complex WFS service, the output location must be a folder.	Workspace; Feature Dataset; Folder
Name	The name of the output feature class or geodatabase. If the input is a simple WFS service, the name will be used to create a feature class in the output location. If the feature class name already exists in the geodatabase, the name will be automatically incremented. By default, the feature type name is used. If the input is a complex WFS service, the name will be used to create a geodatabase in the output location.	String
Complex WFS service (Optional)	Specifies whether the WFS Server parameter value is a complex WFS service. Checked—The WFS service is a complex WFS service. Not checked—The WFS service is not a complex WFS. This is the default.	Boolean
Max Features (Optional)	The maximum number of features that can be returned. The default is 1000.	Long
Expose Metadata (Optional)	Specifies whether metadata tables will be created from the service. This is only applicable for complex WFS services. Checked—Metadata tables will be created in the output geodatabase. Not checked—Metadata tables will not be created in the output geodatabase. This is the default.	Boolean
Swap XY Axis Order (Optional)	Specifies whether the x,y axis order of the output feature class will be swapped. Some WFS services may have the order of the x,y coordinates swapped on the server side, causing the feature class to display incorrectly. Checked—The x,y axis order will be swapped. Not checked—The x,y axis order will not be swapped. This is the default.	Boolean
Page Size (Optional)	The page size that will be used when downloading features from the WFS service. The default is 100. Some servers limit the number of features that can be requested at a time or server performance may be slow when requesting a large number of features in a single request. Use this parameter to request a smaller number of features in multiple pages to avoid server timeouts or maximum feature limits. This parameter is only applicable for simple WFS 2.0 services that support startIndex and count WFS parameters. It will be ignored for older versions of WFS (1.1.0, 1.0.0).	Long

Output Workspace	The output file geodatabase when converting a complex WFS service.	Workspace

Name	Explanation	Data Type
input_WFS_server	The URL of the source WFS service (for example, http://sampleserver6.arcgisonline.com/arcgis/services/SampleWorldCities/MapServer/WFSServer?). If the input is a complex WFS service (is_complex = "COMPLEX"), this can also be the path to the .xml file.	String
WFS_feature_type	The name of the WFS layer to extract from the input WFS service.	String
out_path	The location of the output feature class or geodatabase. If the input is a simple WFS, the output location can be a geodatabase or a feature dataset in a geodatabase. If the output location is a feature dataset, the coordinates will be converted from the source coordinate system to the coordinate system of the feature dataset. If the input is a complex WFS service, the output location must be a folder.	Workspace; Feature Dataset; Folder
out_name	The name of the output feature class or geodatabase. If the input is a simple WFS service, the name will be used to create a feature class in the output location. If the feature class name already exists in the geodatabase, the name will be automatically incremented. By default, the feature type name is used. If the input is a complex WFS service, the name will be used to create a geodatabase in the output location.	String
is_complex (Optional)	Specifies whether the input_WFS_server parameter value is a complex WFS service. COMPLEX—The WFS service is a complex WFS service. NOT_COMPLEX—The WFS service is not a complex WFS service. This is the default.	Boolean
max_features (Optional)	The maximum number of features that can be returned. The default is 1000.	Long
expose_metadata (Optional)	Specifies whether metadata tables will be created from the service. This is only applicable for complex WFS services. EXPOSE_METADATA—Metadata tables will be created in the output geodatabase. DO_NOT_EXPOSE—Metadata tables will not be created in the output geodatabase. This is the default.	Boolean
swap_xy (Optional)	Specifies whether the x,y axis order of the output feature class will be swapped. Some WFS services may have the order of the x,y coordinates swapped on the server side, causing the feature class to display incorrectly. SWAP_XY—The x,y axis order will be swapped. DO_NOT_SWAP_XY—The x,y axis order will not be swapped. This is the default.	Boolean
page_size (Optional)	The page size that will be used when downloading features from the WFS service. The default is 100. Some servers limit the number of features that can be requested at a time or server performance may be slow when requesting a large number of features in a single request. Use this parameter to request a smaller number of features in multiple pages to avoid server timeouts or maximum feature limits. This parameter is only applicable for simple WFS 2.0 services that support startIndex and count WFS parameters. It will be ignored for older versions of WFS (1.1.0, 1.0.0).	Long
