The GMAP Procedure

Using FIPS Codes and Province Codes

The map area identification variable in some SAS/GRAPH map data sets contain standardized numeric codes. The data sets for the United States contain a variable whose values are FIPS (Federal Information Processing Standards) codes. The data sets for Canada contain standard province codes or census division codes. When you use the GMAP procedure with a traditional map data set, the variables that identify map areas in your response data set must have the same values as the map area identification variables in the traditional map data set.

If both a feature table and a response data set contain FIPS Codes or Province Codes, then once both data sets have been sorted, an SQL or DATA step MERGE can be used to merge the two data sets using the variable containing the codes. However, with the merged response and feature table, the identification variable used in the GMAP procedure must be the $GEOREF formatted variable that contains the spatial information. See $GEOREF format for more information.

If the map area identification variables in your response data set are state or province names or abbreviations, convert them to FIPS codes or province codes before using the response data set with one of the map data sets supplied by SAS. U.S. FIPS Codes lists the FIPS codes for the United States and Canadian Province Codes lists the standard codes for Canadian provinces.

Note: Alternatively, you can convert the FIPS code or province codes in your map data set to match the names in your response data. [cautionend]

The MAPS.CNTYNAME data set contains a cross-reference of names and FIPS codes for all counties in the United States. The MAPS.CANCENS data set contains a cross-reference of census district names and codes for Canadian provinces.

Base SAS software provides several functions that convert state names to FIPS codes and vice versa. The following table lists these functions and a brief description of each. See SAS Language Reference: Dictionary for more information.

FIPS and Postal Code Functions
Function	Description
STFIPS	converts state postal code to FIPS state code
STNAME	converts state postal code to state name in upper case
STNAMEL	converts state postal code to state name in mixed case
FIPNAME	converts FIPS code to state name in upper case
FIPNAMEL	converts FIPS code to state name in mixed case
FIPSTATE	converts FIPS code to state postal code
