  1. July 12, 2011 Tips and Tricks for Troubleshooting ArcGIS Desktop 10 Todd Stuber, Chris Fox

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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.

  7. Join Validation Help Topic: Essentials of joining tables

  8. 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

  9. 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

  10. 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

  11. Troubleshooting: Distributing Maps and Data • Creating and unpacking a map package at 10 • Sharing map packages from ArcGIS.com • Demo

  12. 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

  13. Summary: 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
