Feature Services in ArcGIS From simple sketching to sophisticated web editing

What is a Feature Service?

• 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

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

Web Editing Scenarios

• Attachments • Editor tracking

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)

Feature Service usage web editing patterns II

• 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

What is the Geometry Service?

• An ArcGIS Server service for geometry manipulation

• Enhanced in ArcGIS 10 & 10.1: • Offset, Trim/Extend, Reshape, Auto-

Complete • 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?

• 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

Summary

• ArcGIS Server 10 features built-in web editing capabilities

• Enabling many exciting applications - Crowd sourcing, geocollaboration, web editing…

• New Feature Service • Out of the box editing clients

- ArcGIS.com Viewer - ArcGIS Viewer for Flex

• ArcGIS Web Mapping APIs • Geometry Service and Server Object Extensions

Agenda

Editing native spatial types in databases

• Feature service against non versioned data • Last-in wins • Changes directly applied on database • Use Spatial Data Server

Not Versioned Data

Feature Service

Versioned editing

• 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

Isolated editing

• Web edits against an isolated geodatabase (in DMZ or off-site deployment)

• Changes validated and synchronized to geodatabase
