Road Ahead – Analysis Capabilities (ArcGIS 10.1)
Jian Lange

2. Spatial Analysis in 10.1 Make it Easy Make it Accessible
Improve the Science

3. Agenda New Analysis tools and enhancements
Spatial Statistics
Geostatistical Analyst extension
Improvements in Network Analyst Extension

4. New Analysis Tools and Enhancements
Identify space-time clusters
(Considering both space and time in Hotspot analysis)
3000 meters in space combined with 3 weeks in time moving window for hot spot analysis
Identify features neighboring in space
As well as neighboring in Time!

5. New Analysis Tools and Enhancements
Group Similar Features
Foot and Mouth outbreaks in 2001

6. New Analysis Tools and Enhancements
Find appropriate scale of analysis
(Incremental spatial autocorrelation )
1 Mile Radius
¼ Mile Radius
½ Mile Radius
Available in ArcGIS 10 for as a Sample Script

7. New Analysis Tools and Enhancements
Exploratory regression
Available in ArcGIS 10 for as a Sample Script

8. New Analysis Tools and Enhancements
Areal Interpolation
Obesity by school zone
Obesity surface and error surface
Obesity by census block
Cast data to a different geometry
School zones to census tracts
Model and fill-in missing data
What it does. (cast data)
Uses geostatistical methods.
Important for many analyses that need all of your data to be in the same geometry.

9. New Analysis Tools and Enhancements
Empirical Bayesian Kriging
Spatial relationships are modeled automatically
Very easy to use (few parameters)
Available as a GP tool
Results often better than traditional kriging
Uses local models to capture small scale effects
Doesn’t assume one model fits the entire data
How many have used GA?
What GA does…
Loads of flexibility…
How many of you take the defaults?
… so the GA team built EBK… fits the data to a geostatistical model for you… but also (!!) subsets your data and fits each subset to a model so if the spatial relationships you are modeling change across the study area, these differences will be captured and, ultimately, you get better predictions
Eric initially didn’t think this would do as good a job as using the GA wizard to carefully optimize model parameters… in fact, he was very pleased with the results.

10. Faster Network Analysis
Significantly faster service area solver
Service Area

11. Routing with Historical and Real-Time Traffic
Point to point routes
Optimize stop sequence
Time windows
Time aware

12. All Solvers Are Time Aware
Can use historical or real- time speeds
Solution is different based on time of day
Provides better or updated ETAs for existing routes
To perform time aware analysis, specify…
Traffic aware cost attribute
Time of day

13. Enhanced Restrictions
Frequently requested enhancement
More flexible restriction model
Managed using restriction attributes with parameters
Roads can be:
Preferred
Avoided
Prohibited entirely
Examples:
Prefer truck routes
Avoid toll roads

14. DEMO Find route that avoids toll roads
Find route that uses designated truck route roads

15. New Network Analysis Services in ArcGIS 10.1
Use network analysis services from ArcGIS Online
Easily publish your own services using tools in Server toolset
