Geocoding is the process of adding
location information to an existing data set that contains address data. Location information is the X and Y coordinate data for the street
addresses on a map. The geocoding facility in SAS/GIS software attempts to
match each address in a SAS address data set to a location on a map. If a
match is found, the X and Y coordinates of the address are added to the address
data set. Other attribute information about the matched location can also
be added to the address data set.
SAS/GIS software provides an interactive interface for
geocoding through the GIS Geocoding window. The window is convenient for
geocoding individual address data sets. However, if you have a large number
of data sets or a data set with a large number of observations that you want
to geocode, you might find the batch geocoding facility to be
more convenient. The batch geocoding facility in SAS/GIS allows data to be
geocoded without invoking SAS/GIS, without user intervention, and with improved
performance. For example, you can set up a program to run overnight to geocode
address data sets without user interaction.
