  1. July 23 - 27, 2012 Geocoding – An Introduction Miriam Schmidts Agatha Wong

  2. Agenda • What is geocoding? • ArcGIS geocoding components • Geocoding workflow

  3. What is Geocoding? Lake St. LakeESRI • Geocoding: A GIS operation to transform a description of a location—such as a pair of coordinates, an address, or a name of a place—to a location on a map.

  4. What is Geocoding? • Geocoding: A GIS operation to transform a description of a location—such as a pair of coordinates, an address, or a name of a place—to a location on a map.

  5. Demo • Interactive • Reverse

  6. Ways to do Geocoding Reverse Interactive Batch

  7. Ways to find locators for geocoding ArcGIS OnlineGeocode Services StreetMap PremiumProducts from Esri Geocoding can be done with locators or geocode services from various sources Build your ownlocators with ArcGIS Desktop Users’ locators sharedat Arcgis.com

  8. Address Locator Geocoding Components Table of Addresses Geocode services Geocoded features

  9. Geocoding with a geocode service Table of Addresses Geocode services Geocoded features

  10. Geocoding with a geocode service • ArcGIS Online (arcgis.com)

  11. Geocoding with a geocode service • Geocode services published with ArcGIS Server

  12. Address Locator Geocoding with a locator Table of Addresses Geocoded features

  13. Geocoding with a locator Build or obtain reference data Determine addresslocator style Build anaddress locator Locate addresses

  14. Reference Data • Many sources • StreetMap data • Government data • Data vendors • Data shared on ArcGIS.com

  15. Geocoding Work Flow Build or obtain reference data Determine addresslocator style Build anaddress locator Locate addresses

  16. What is an Address Locator Style • Template containing geocoding properties • Choose style based on properties of: • Address data: address information to geocode • Reference data: geometry and attribute values Locator styles can be customized to support international addresses

  17. Locator Style Example US Address - Single House Reference Data = Points or Polygons

  18. Geocoding Work Flow Build or obtain reference data Determine addresslocator style Build anaddress locator Locate addresses

  19. Address Locators in ArcGIS • Defines the process for geocoding • Self-contained dataset • stores address attributes, indexes, and queries • independent from the reference data • Stored in a File folder or geodatabase Create new address locator

  20. Demo • Create an addresslocator • Modify the locator properties

  21. Composite Locator • Combines multiple locators • Geocode against multiple datasets • Cascade/Fallback geocoding • Spatially disjointed datasets

  22. Demo • Create a composite locator

  23. Geocoding Work Flow Build or obtain reference data Determine addresslocator style Build anaddress locator Locate addresses

  24. Geocoding Toolbar A quick way to geocode address Review/Rematch Address Inspector Use map extent Geocode Addresses Address Input box (Find address in a single-line format) Manage Address Locators (List of default locators)

  25. Find Tool • Choose locator • Specify address • Show all candidates • Use Map Extent • My Places

  26. Geocoding an address in ArcMap

  27. Additional Fields in Output Feature Class • Status • Score • Match_type • Addr_type • Side • Match_addr • Arc_Street / Arc_ZIP

  28. Demo • Geocode addresses

  29. Summary – Geocoding with ArcGIS 10.1 • What is geocoding? • ArcGIS geocoding components • Geocoding work flow

  30. More… If you want to learn more about: • The geocoding engine • How to manage performance • How to fine tune locators • Sharing/packaging locators Please stay and attend the Geocoding – Advanced Techniques workshop.

  31. Resources and References • ESRI Resource Centers http://resources.arcgis.com/en/communities/geocoding
