Feature
Service
• Feature Template based editing: Well defined Information Model
• Feature Service: An editing web service for your geodatabase
• Edit from many clients

11. What are Feature Templates?
• A shortcut to the things that people edit
• Feature Template defines:
- Symbol
- Editable and read-only attributes
- Default values
- Preferred drawing mode
• Authored in ArcMap, used by all clients
• Structured data collection with an
intuitive user experience

12. What is a Feature Service?
3 Client renders

• New in ArcGIS Server 10
• Designed for web editing 2 Query

- Push changes into the geodatabase over the internet Attributes

• Also excellent for querying Delete

- Fetch geometries and attributes
- Client renders features (Thematic mapping, maptips…)

How Feature Services work?
(Simplified)

13. How to create a web editing application?

your data Feature
Application
and templates Service

14. Preparing your data
• Define your geodatabase model
- Feature types (geometry, attributes, attachments)
- Not supported: Dimensions, TINs, Rasters…
- Business rules
- Default attributes, domains, subtypes, relationships…
• Make sure it can be edited
- Must be registered within an ArcSDE geodatabase
- Grant read-write permissions
- No need to version your data
Tip: If ArcMap cannot edit it, a Feature Service will not either

15. Authoring your map document for editing
• Define your feature templates in ArcMap
- Field visibility, field-name aliases, read-only fields, default attributes
- Symbology (not all renderers and symbols are supported. See next slide)
- Preferred drawing mode: Freehand, polygon, rectangle…
• Refine your map document
- If versioned, select the version to edit
- Eliminate unnecessary data from your map document
- Author, credits, summary etc

16. Feature Services and ArcGIS symbology
• Supported renderers:
- Simple, Unique Value, Class Breaks
• Symbology:
- All symbols are supported, but your client may downgrade*
- Simple Marker and Picture Marker symbols
- Simple Line symbols
- Simple and Picture Fill supported
* Well… there are ways to prevent that. We will see that later!

17. Feature Service symbology demo

18. Publishing your Feature Service
• Feature Service is a capability of a map service
• Must publish a map service, then enable Feature
Access
- Tip: Ideally publish from an MSD. Not an MXD
• Securable like any other service
From ArcGIS Desktop
From ArcGIS Server Manager

19. If things go wrong…
• Common reasons why a Feature Service will not
start:
• ArcGIS SOC user cannot access the data
• No editable ArcSDE workspace in your map
• More than one ArcSDE workspace in your map
• Renderer not supported
• Look at the logs!
Symbology downgrades will show as warnigns, but your service will publish.

23. Agenda
• Overview of Editing in ArcGIS
• The basics of Web Editing in ArcGIS Server 10
• Web Editing scenarios
• Typical Architectures
• Q&A

24. Web Editing Scenarios
• Web Editing with the Viewers
• Attachments
• Handling complex symbology/geometries
• Attribute Edits
• Sophisticated Web Editing

25. Web Editing with the Viewers
Configurable out of the box applications
• Configurable app
• Look and feel
• Capabilities
• Map content
• Ideal for the creation of proofs of concept and as a basis for
focused applications
• Extensible/Customizable
• You host it, you control it

26. What are geodatabase attachments?
• A file associated to a feature
• Video, picture, pdf, zip…
pdf,
• Stored in the geodatabase as a BLOB
• 1 to many relationship
• One feature, many attachments
• Retrieve and edit from Desktop and the Web

27. DEMO
Attachments

28. Handling complex geometries and symbology

29. What is a feature layer?
• It’s the client counterpart to the Feature Service
• Manages how features are:
• Fetched to the client
• Snapshot, On demand, Selection only
• Rendered
• Used in combination with
• Attribute inspector, Template Picker, Attachment Editor
• Editor widget
Template picker
Attribute
inspector

30. Feature Service usage web editing patterns I

• Fetch all at once (Snaphsot mode)

• Subset of ArcGIS symbology
• No more than a few hundred features in display*
• Careful with large polys/polylines
• Take advantage of maptips (popups) Feature

* Be smart about using scale dependencies, generalize, filter… Render features client-side

31. Feature Service usage web editing patterns II
Rendering features server-side
• Render features in the server (Map service)
• Refresh map after every update
• Features being edited displayed in client 1 Get Map
• Through FeatureLayer Selection mode Get Feature 2

35. What is the Geometry Service?
Web Browser
• An ArcGIS Server service for geometry manipulation
• Enhanced in ArcGIS 10:
• Offset, Trim/Extend, Reshape, Auto-Complete
Auto-
• Cut, Difference, Intersect, Union
• REST interface only
• Use in combination with Feature Service
• To aid in editing workflows
• Cut, Reshape…
Geometry Feature
• Also validating business rules! Service Service
Geodatabase

36. What are Server Object Extensions?
Web Browser
• That’s how you extend ArcGIS Server
• With new web services
• To access fine grained ArcObjects
• Implement business logic on your server
• Accessible via REST and SOAP
• Multiple applications for editing
• Validating topology
• Rebuilding network datasets
• Implementing validation rules

37. The challenge is the user experience
• Adding many tools is an easy and often unnecessary part
• Build focused editing apps
• The necessary tools, no more
• The workflow drives the design, not the opposite!
• Start by selecting the right client
• Do not reinvent the wheel
• Do not push the technology beyond its comfort level
• Or your users!
• Develop if needed
