Web-based editing allows a larger group of people to add to and improve on your data. These include fieldworkers, analysts in other departments of your company, or perhaps even crowdsourced volunteers who may be able to make valuable contributions to your data given a user-friendly editing interface.
In this tutorial, you'll learn how to set up your feature service data so that it can be used when working with maps offline. To do this, you'll set up a fictitious enterprise geodatabase for the purposes of managing shoreline bird sightings.
This tutorial demonstrates how to do the following:
- Set up an enterprise geodatabase using a database platform such as PostgreSQL or Oracle.
- Author a map document that supports web editing. This involves designing the map document to be compliant with the feature service. In this tutorial, the feature service allows users to add and edit bird sightings in your enterprise geodatabase.
- Prepare your enterprise geodatabase for publishing to ArcGIS Server. This involves setting up the data to support the feature service sync capability, connecting to ArcGIS Server, and registering your database with the server.
- Publish your map document as a map service with Feature Access and sync capabilities enabled. This creates a feature service endpoint through which client applications can edit the bird sightings in your map while offline.
Before beginning this tutorial
If you've just installed ArcGIS Server, consider reading the following before you begin this tutorial:
Set up an enterprise geodatabase
Feature services can be published using data from an enterprise geodatabase. That's because enterprise geodatabases are designed to be edited simultaneously by multiple users, which is the situation you'll encounter in this tutorial. Enterprise geodatabases support a variety of database platforms, such as PostgreSQL, SQL Server, and Oracle.
For the purposes of this tutorial, you'll need to set up an empty enterprise geodatabase to store the features you create and edit. If you've already installed a supported database platform and have an empty geodatabase set up, proceed to the next section. If you don't, you'll need to create a new enterprise geodatabase by installing an appropriate database platform on your machine. Before doing so, make sure that your operating system and license level of ArcGIS Server and ArcGIS Desktop support the database platform you want to install.
The following topics describe the configuration process for each database platform. They also include links to ancillary topics that describe how to create a new enterprise geodatabase and properly configure it for use within your organization. Once you've installed the appropriate database platform and created a new geodatabase, proceed to the next section in this tutorial.
Create a new database user
Once you've created an empty enterprise geodatabase, you'll need to create a new database user to manage your edits. To do this, you need to connect to your geodatabase as the database administrator, create a new database user, and reconnect to the database as the new user.
Connect to the database and create a new user
- In ArcCatalog or the Catalog window in ArcMap, expand the Database Connections folder and double-click Add Database Connection .
The Database Connection dialog box opens.
- From the Database Platform drop-down list, choose the type of database with which you want to connect.
- Enter the appropriate database properties and authentication credentials to connect to the database. If you need help, see Database connections in ArcMap to learn how to enter the correct information to connect to your database.
You must connect as a database administrator to create a user.
- Click OK. The connection to your database appears in the Database Connections node .
- Right-click your new database connection and choose Administration > Add User. This starts the Create Database User geoprocessing tool.
- On the Create Database User dialog box, provide a new database user name and database user password, for example, User: editor, Password: tutorial.
- Click OK.
The new user is created in the database and has been granted the privileges necessary to create tables and feature classes.
Reconnect to the database as the new user
- In ArcCatalog or the Catalog window in ArcMap, expand the Database Connections folder, and double-click Add Database Connection .
- On the Database Connection dialog box, provide the authentication credentials for the user you created in the previous section.
- Click OK.
You are now connected to the database as the new user.
- In the Database Connections folder , delete the first connection you established to your database. This helps eliminate confusion when specifying your database connection file later in the tutorial.
Author a map document to support feature services and web editing
After you've set up your enterprise geodatabase, you can begin the work of authoring a map document to support the feature service you'll use for web editing.
In this section of the tutorial, you'll do the following:
- Create an attribute domain to enforce data integrity.
- Create a feature class to represent bird sightings.
- Create feature attachments so users can add external media to their bird sightings.
- Define layer renderer and symbology.
- Add a basemap for context.
- Add bird sightings to your map.
To get started, follow the steps in the sections below.
Create an attribute domain
To enforce data integrity when editing, you'll configure an attribute domain to limit the sightings added to your database to a few specific bird types.
- Start ArcMap, open a new empty map document, and save the map document. The map document does not have to be saved in a location that is visible to the account running ArcGIS Server.
- In the Catalog window, expand the Database Connections folder .
- Right-click your database connection and choose Properties .
- On the Database Properties dialog box, click the Domains tab.
- In the Domain Name field, click the first cell and type Type.
- In the Description column next to the domain name, click the first cell and type Bird Type.
- In the Domain Properties section, click the cell next to Field Type and choose Long Integer.
- Click the cell next to Domain Type and choose Coded Values.
- In the Coded Values section, click the first cell under Code and type 0.
- In the Description column next to the code, click the first cell and type Alcid/Pelagic.
- Enter the remaining bird types in the Coded Values section from the following table:
- Click OK.
Create a feature class
In this section of the tutorial, you'll create a point feature class that represents the various types of birds in your bird sightings geodatabase. This includes defining the spatial reference of the feature class and assigning your domain to a new field in the feature class table. To get started, follow these steps:
- In the Catalog window, right-click your database connection and choose New > Feature Class.
- On the New Feature Class dialog box, type shoreline_birdsightings in the Name field.
- From the Type drop-down list, choose Point Features. Click Next.
- In the coordinate system search box, type web mercator (auxiliary sphere) and click Search .
- In the results list, choose WGS 1984 Web Mercator (auxiliary sphere). This is the same coordinate system used by ArcGIS Online and allows you to seamlessly overlay your feature service with ArcGIS basemap services. Click Next.
- In the XY Tolerance panel, accept the defaults and click Next.
- In the Configuration Keyword panel, accept the defaults and click Next.
- In the Field Properties panel, in the Field Name column, click the cell below SHAPE and type TYPE.
- In the Data Type column, click the cell below Geometry and choose Long Integer.
- Edit the properties of the field by clicking the cell to the right of Domain and choosing Type. This specifies that the field only accepts the values defined in the Type domain you created earlier in the tutorial.
- In the Field Name column, click the cell below the TYPE field and type COMMENTS.
- Specify the data type of the COMMENTS field to be Text.
- Click Finish.
Your feature class is created and automatically added to the table of contents.
Create feature attachments
In this section, you'll add feature attachments to your feature class. An attachment is a media file, such as an image, PDF, or video, that can be associated with a feature when it's created or edited. For example, when a user adds a shoreline bird sighting to the database, they can attach a photograph of the bird for additional context. When the feature is clicked, the attachment displays.
- In the Catalog window, expand the connection to your enterprise geodatabase.
- Right-click the shoreline_birdsightings feature class and choose Manage > Create Attachments.
ArcMap adds a new table to contain the attached files and a relationship class to manage the link between the features and their attachments.
Define layer renderer and symbology
In this section, you'll define a layer renderer and symbology for the various bird types in your database. The way you symbolize your features is important, since features display on the web using the symbology defined in the map document.
- In the ArcMap table of contents, click List by Drawing Order .
- Right-click the shoreline_birdsightings feature class and click Properties .
- On the Layer Properties dialog box, click the Symbology tab.
- On the Show dialog box, click Categories > Unique values. This specifies that you'll use a unique value renderer for all the features in your database.
- In the Value Field drop-down list, choose type.
- Click Add All Values. Each bird type is added to the list.
- Uncheck the check box next to the <all other values> symbol.
- Double-click the symbol next to the Alcid/Pelagic bird type.
- On the Symbol Selector dialog box, type alcid in the search field and click Search .
- Select the Alcid/Pelagic Bird symbol and increase its size to 25.
- Click OK. The symbol is applied to the Alcid/Pelagic bird type.
- Based on the following criteria, use the symbol search to specify the symbology for the remaining bird types:
- When you're finished specifying the symbology, click OK on the Layer Properties dialog box. The symbology displays in the ArcMap table of contents.
|Bird type||Search criteria||Symbol||Size|
question mark (In the results list, choose the ESRI_Optimized style.)
Add a basemap for context
For context, you'll add a basemap to your map document from ArcGIS Online.
- From the main menu in ArcMap, click File > Add Data > Add Basemap.
- Choose Light Gray Canvas as the basemap and click Add. The basemap is added to your map display.
- Zoom in to an area of interest, for example, a familiar coast or shoreline and save your map document.
Add features to your map
Now that you've symbolized your features appropriately and added a basemap for context, you'll set up the proper editing environment and add features to your map.
- In ArcMap, display the Editor toolbar by choosing Customize > Toolbars > Editor from the main menu.
- On the Editor toolbar, click Editor > Options.
- On the Editing Options dialog box, click the Versioning tab.
- Since the data in your geodatabase is nonversioned, uncheck Edit a version of the database with the ability to undo and redo. Disabling this option allows you to edit data that is nonversioned.
- Click OK.
- On the Editor toolbar, click Editor > Start Editing. A default feature editing template is created based on the symbology of the editable layers in your map document. You'll use this feature template in the next step to add features to your map.
- On the Editor toolbar, click Create Features .
- In the Create Features window, select a bird type and add it to the map.
- On the Editor toolbar, click Attributes .
- In the Attributes window, add a comment and attachment to the feature you created. You can search the web for a picture of the bird you chose, save it as an image, and add it as an attachment.
- In the table of contents, right-click the shoreline_birdsightings feature class and choose Open Attribute Table.
- In the Table window, verify that your feature and comments are included in the table. Close the table when you're finished.
- Repeat steps 7 through 12 to add another bird sighting to your map.
- On the Editor toolbar, click Editor > Stop Editing. When prompted to save your edits, click Yes.
- Save your map document.
Prepare your enterprise geodatabase for publishing
Now that you've created and edited your map document, you're ready to prepare your data for publishing. In this tutorial, nonversioned data is used. To prepare the data, you'll need to do the following:
- Add Global IDs
- Enable archiving
- Remove the basemap layer from the map
- Connect to ArcGIS Server
- Register your database with the server
Add Global IDs
Global IDs need to be added to your data to use your feature service locally in a client application. This allows the edits made to your database to be uniquely identified.
- Double-click your geodatabase connection in the Catalog window to see its contents.
- Right-click the shoreline_birdsightings feature class, and choose Manage > Add Global IDs.
- In the Confirm Add Global IDs dialog box, click Yes.
Since the data in your database is nonversioned, you'll need to enable archiving for your feature service to be used locally by client applications. Archiving records changes made to the data, which allows the local data to be synchronized back to the feature service.
To enable archiving, right-click the shoreline_birdsightings feature class, and choose Manage > Enable Archiving.
Remove the basemap layer
- In the ArcMap table of contents, right-click the basemap and choose Remove.
- Save your map document.
Connect to ArcGIS Server
- In the Catalog window in ArcMap, expand the GIS Servers node.
- Double-click Add ArcGIS Server .
- Choose Publish GIS services and click Next.
- For Server URL, type the URL of the ArcGIS Server site you want to connect to. The default is http://gisserver.domain.com:6080/arcgis. If you or your server administrator installed ArcGIS Web Adaptor, the URL varies depending on the Web Adaptor configuration. See Components of ArcGIS URLs for additional URL examples.
- In the Server Type drop-down list, make sure ArcGIS Server is selected.
- For the purposes of this tutorial, accept the default staging folder location.
- If your server administrator has enabled security for your site, provide your user name and password. Click Finish.
A publisher connection to ArcGIS Server is created in the GIS Servers node.
Register your database with ArcGIS Server
Since your map document references data residing in an enterprise geodatabase, you'll need to register the enterprise geodatabase with ArcGIS Server. Registration provides ArcGIS Server knowledge about the location of your enterprise geodatabase and the data referenced by your map document. This helps you validate that you're ready to publish.
- In the Catalog window, right-click your publisher connection to ArcGIS Server and select Server Properties.
- On the ArcGIS Server Properties dialog box, next to the Registered Databases panel, click Add .
- On the Register Database dialog box, provide a unique name for the registered database. Names can be alphanumeric and contain spaces, for example, Shoreline Bird Sightings GDB.
- Next to the Publisher database connection section, click Import.
- On the Browse for a Database Connection dialog box, click the Look in drop-down list and choose Database Connections.
- Select the connection to your database and click Select.
- In the Server database connection section of the Register Database dialog box, make sure the check box next to Same as publisher database connection is checked. This specifies that both ArcMap users and web users accessing the feature service can view and manipulate the data in the bird sightings geodatabase simultaneously. For more information, see About registering your data with the server.
- Click OK. Your enterprise geodatabase is registered with the server and appears on the Registered Databases dialog box.
- Click OK to close the ArcGIS Server Properties dialog box.
Publish a map service with feature access enabled
Now that you've done the work of preparing your database, you can publish your map document with the Feature Access capability enabled. This creates a feature service endpoint to your map service through which clients, such as a web application, can access and edit the features in your map.
As part of this step, you'll also enable the Sync capability. This allows the data in your feature service to be used offline in client applications.
- From the main menu in ArcMap, choose File > Share As > Service.
- In the Share as Service window, choose Publish a service. Click Next.
- In the Publish a Service dialog box, choose the publisher connection to ArcGIS Server you set up earlier in the tutorial.
- By default, the name of the map document dictates the service name. Instead of using the default, type Shoreline_BirdSightings. Click Next.
- By default, services are published to the root folder (root) of ArcGIS Server. Accept the default location and click Continue.
The Service Editor dialog box displays. Use Service Editor to choose what users can do with your feature service and take fine-grained control of how the server exposes your feature service.
- Click the Capabilities tab.
- By default, mapping and KML are enabled. Choose Feature Access. Enabling this option creates an associated feature service with your map service that allows clients to perform feature editing over the web.
- In the left pane of the Service Editor, click Feature Access.
- In the Feature Access dialog box, enable the Sync capability.
- In the left pane of the Service Editor dialog box, click Item Description, and enter the following summary and tags for your service:
- Summary: The Shoreline Bird Sightings feature service allows users to add common shoreline bird sightings to a map, attach photographs to sightings, and input comments.
- Tags: shoreline, bird, sighting
- Click Publish .
Your feature service is published to ArcGIS Server. When the publishing process completes, you're ready to consume your shoreline bird sightings feature service in client applications. You can also use a client application to create a local copy of your features for offline use.
Leverage the sync capability
ArcGIS clients and developer SDKs will progressively add support for the sync capability in feature services, which was introduced in ArcGIS 10.2.1. The first clients to support working with maps while offline are Collector for ArcGIS and ArcGIS Runtime SDKs. You cannot enable the sync capability on feature services published prior to ArcGIS 10.2.1.
Other clients can access the sync capability through the ArcGIS REST API.
If you use ArcMap to edit feature services that are part of an offline editing workflow, be sure to keep the ArcMap editing option to Automatically save changes after each edit enabled. If you disable this option, synchronization from any other client will be blocked until you close your edit session.
