Feature Service
What is a Feature Service? 3 Client renders features
•
Added in ArcGIS 10
•
Designed for web editing -
Push changes into the geodatabase over the internet
•
Also excellent for querying -
Fetch geometries and attributes
-
Client renders features (Thematic mapping, maptips…)
•
Stateless, quick, RESTful service

How Feature Services work? (Simplified)
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

Feature Service usage web editing patterns I
• Render features in the client (Feature Layer) • Fetch all at once (Snaphsot mode) • Or as needed (On demand mode)
• Subset of ArcGIS symbology • No more than a few hundred features in display* • Careful with large polys/polylines • Take advantage of maptips (popups)
* Be smart about using scale dependencies, generalize, filter…

• Render features in the server (Map service) • Refresh map after every update • Features being edited displayed in client •

Through FeatureLayer Selection mode
• Full symbology • Many and complex features • Use MSDs whenever possible

Sophisticated Web Editing
What is the Geometry Service? Web Browser
• An ArcGIS Server service for geometry manipulation • Enhanced in ArcGIS 10 & 10.1: • Offset, Trim/Extend, Reshape, AutoComplete •
Cut, Difference, Intersect, Union
•
REST interface only
•
Use in combination with Feature Service • To aid in editing workflows • Cut, Reshape… • Also validating business rules!

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 •

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
Internet Editing for ArcGIS Desktop tool For sophisticated editing or ‘disconnected’ scenarios
• A Map Service that you can edit from Desktop

Q&A
Editing native spatial types in databases Web Browser
•
Feature service against non versioned data
•
Last-in wins
•
Changes directly applied on database
•
Use Spatial Data Server
Feature Service
Not Versioned Data
Geodatabase
Versioned editing Web Browser
•
Feature service on a particular ‘web edits session’
•
Last-in wins
•
Updates from feature service validated before posting to master version
•
Typical in intranet or ‘safe’ environments where contributions are not trusted
Edits on version X Feature Service
Periodic validation And Post
Geodatabase
Isolated editing Web Browser
•
Web edits against an isolated geodatabase (in DMZ or off-site deployment)
•
Changes validated and synchronized to geodatabase
•
Crowd-sourced data (internet)
Edits on version X Feature Service
Periodic validation And Post
