Cheap Geocoding: SAS/GIS and Free TIGER Data
Geocoding is the process used to convert address data to map coordinates.
This presentation, given at SUGI 30, introduces geocoding and examines several techniques
for geocoding address data using SAS/GIS and free data.

Randomly Scatter Geocoded Centroids
Geocode Addresses with Bad ZIP Codes
Plot Geocoded Points with PROC GMAP
Street Level Geocoding
Geocoding Examples
PROC GEOCODE ZIP+4 Lookup Data
PROC GEOCODE is a new procedure in SAS/GRAPH. It performs geocoding using ZIP/ZIP+4 postal codes and also by city/state.
This zip archive contains a SAS transport file of nationwide data for US geocoding, a ReadMe file with instructions and a SAS program to cimport the transport file into a SAS data set. The ZIP+4 centers are based on the 2006 Second Edition TIGER/Line files from the US Census Bureau.
This file has been updated with a better index. The ZIP+4 X/Y values did not change. NOTE: This is used by the PROC GEOCODE product for geocoding by ZIP+4. This product is available with SAS 9.2 Phase 1.
This is a large file and downloads slowly. The zipped file is 300 Mb. Unzipped it requires 1.7 Gb of storage.

SAS/GIS Lookup Data, Maps and Examples
The zip archive contains pre-built nationwide data used by SAS/GIS for
street level geocoding in the US. The street data are based on
TIGER 2000 Line files. It also contains a sample geocoding program and
a US map.
This is a large file and downloads slowly. The zipped file is 900 Mb. Unzipped it requires 3.5 Gb of storage.
