July 12, 2011
Some common customer issues
• Working with large data sets
• Joining data
• Selecting features using attribute queries
• Distributing and sharing maps and data
• Making attribute field calculations
Troubleshooting: Working with large data sets
• Two types of large data sets:- Large number of features
- Large number of vertices per feature
• Symptoms:- Slow drawing
- Slow editing
- GP tools fail or take excessively long to complete- Out of memory errors
Troubleshooting: Working with large data sets
• How to determine how many features you have:- Go to last record in Table View
- Get Count GP Tool
• Enhancements at 10 to deal with extremely large number of features:- Spatial Join
- Select By Location
- Base Maps
Troubleshooting: Working with large data sets
• Large number of vertices are often more impactful on performance.
• Avoid reading or creating extremely large single features.- E.g. Dissolve All
- Size of single features DT can handle is based on available memory
• New tools at 10 to deal with large number of vertices:- Dice tool
- Blog Post: Dicing Godzillas
(features with too many vertices)
- Generalize tool
Troubleshooting: Joining data
• One of the most common customer issues is “Help my join didn’t work!”
• At 9.3.1 and earlier, Troubleshooting was dependant on user’s knowledge of data types.
• ArcGIS 10 introduces a new Troubleshooting tool -Join Validation.
Join Validation
Help Topic: Essentials of joining tables
Troubleshooting: Attribute queries
• Use the SQL reference help topic
• Useful functions:- “IN” comparison operator:
"STATE_NAME" IN ('Alabama', 'Alaska', 'California', 'Florida')
- Sub Queries: "GDP2006" > (SELECT MAX("GDP2005") FROM countries)
- Date Queries with Joins
• Demo
Troubleshooting: Attribute queries
• Finding (and deleting) duplicate records- At 9x, required a complex
query
- New GP tools at 10
- Can find duplicate attributes or shapes
• Demo
Troubleshooting: Distributing Maps and Data
• Map Packages (.mpk) new at 10
• Solutions to 9x workflows:- Sharing data and maps
- Clip and ship
- Putting data onto CDs, DVDs
Troubleshooting: Distributing Maps and Data
• Creating and unpacking a map package at 10
• Sharing map packages from ArcGIS.com
• Demo
Troubleshooting: Making field calculations
• Most calcs can be performed with a few common functions
• Use the help!
• The 9x VBA tool has been replaced with Python / VbScript GP tool @ 10- Advantages
- Migration issues
• Results Tab for debugging
• Demo
