The %GCBATCH macro sets
the input parameters for the batch geocoding program. The macro accepts
the following information:
-
the name of the address data set
to geocode
-
the variable names in the address
data set
-
the name of the map entry
-
the library in which to store geocoding
data sets, and whether new copies of the data sets are created
-
the name of an alternate ZIP code
centroids data set that is used instead of SASHELP.ZIPCODE
-
the names of any additional polygonal
composites to add to the address data set.
The %GCBATCH macro has
the following general form. The elements within the %GCBATCH macro
can appear in any order, but they must be separated by commas.
%GCBATCH(
<GLIB=geocoding-library,>
<ZIPD=ZIP-centroids-data-set,>
GEOD=address-data-set,
<NV=name-var,>
AV=address-var,
CV=city-var,
<SV=state-var,>
<ZV=ZIP-var,>
<P4V=ZIP+4-var,>
MNAME=map-entry,
<PV=area-composite-list,>
<NEWDATA=YES|NO> );
where
specifies the name
of the variable that stores the complete street address in the address
data set that you want to geocode. This includes the house number,
street name, and street type (for example, 3922 Oak Avenue). This
parameter is required.
specifies the name
of the variable that stores the city name portion of the address in
the address data set that you want to geocode. This parameter is required.
specifies the address
data set that you want to geocode. This parameter is required.
specifies the libref
for the SAS library where all of the sorted and summarized chains,
nodes, and details data sets that are created for the geocoding process
are stored. This parameter is optional.
Note: The SAS library that you
specify for the GLIB= argument should be on a volume that has a large
amount of free space because the geocoding data sets might be quite
large. Also, to take full advantage of the geocoding facility, you
should specify a permanent SAS library. The default for this variable
is WORK, but data sets in the WORK library are deleted when the SAS
session is terminated, so the geocoding data sets are lost. If geocoding
data sets already exist in the specified library at the start of the
geocoding process, the geocoding facility checks their creation dates
against the creation date of the chains data set. The geocoding data
sets are created again only if the chains data set has a more recent
creation date. The first time you geocode with a particular chains
data set, the process takes considerably longer because these geocoding
data sets are being created, sorted, and indexed. Subsequent geocoding
times, however, are much faster as long as the parent chains data
set has not been modified.
specifies the name
of the GISMAP entry for the SAS/GIS spatial database (the chains,
nodes, and details data sets) that you are using for geocoding. The
geocoding process uses the projection information in the map entry
to ensure that the X and Y coordinates that are returned for the address
will be in the same coordinate system as the spatial data for the
map. The MNAME= argument should use the form libref.catalog-name.entry-name. This parameter is required.
specifies whether the
geocoding lookup data sets are created again if they already exist.
The default is NEWDATA=NO. If you set NEWDATA=NO, the geocoding facility
searches the SAS library that you specified with the GLIB macro variable
for geocode data sets that were created for the spatial entry. The
geocoding facility checks the creation date of existing geocode data
sets against the creation date of the spatial entry. If the creation
date of the geocode data sets is more recent than the creation dates
of the spatial entry, the geocoding facility uses the geocode data
sets. Otherwise it creates new geocode data sets.
Use NEWDATA=YES to
force the geocoding facility to build new versions of the geocoding
data sets. You should specify NEWDATA=YES if the existing geocoding
data sets were created with an earlier version of
SAS/GIS software.
This parameter is optional.
specifies the name
of the variable that stores the name portion of the address in the
address data set that you want to geocode.
This parameter is optional.
specifies the list
of polygonal (area) composite values that you want added as variables
to the address data set along with the X and Y coordinates of the
address. By default, no other variables are added. Use spaces to separate
composite names in the list. For example, the following specification
adds the county and census tract and block values along with the address
coordinates:pv=county tract block, This parameter
is optional.
specifies the name
of the variable that stores ZIP+4 postal codes in the address data
set that you want to geocode.
This parameter is not
required, but the accuracy of the geocoding process might be reduced
if you omit it.
specifies the name
of the variable that stores the state or province name portion of
the address in the address data set you want to geocode.
This parameter is not
required, but the accuracy of the geocoding process might be reduced
if you omit it.
ZIPD=
ZIP-centroids-data-set
specifies a data set
that contains the coordinates of the centers of ZIP code zones. (If
an address includes a ZIP code and the street address cannot be matched,
the geocoding facility supplies the ZIP code centroid coordinate instead
of the address coordinate.) The default is ZIPD=SASHELP.ZIPCODE, which
specifies the SASHELP.ZIPCODE data set that is supplied with SAS software.
Updated data sets are available from the SAS Maps Online area at http://support.sas.com.
This parameter is optional.
specifies the name
of the variable that stores the ZIP code portion of the address in
the address data set that you want to geocode.
This parameter is not
required, but the accuracy of the geocoding process might be reduced
if you omit it.
