The GMAP Procedure

PROC GMAP Statement

Identifies the map data set and the response data set that contains the variables associated with the map. Optionally causes the procedure to display all map areas and specifies annotation and an output catalog.

Requirements: Both a map data set and a response data set are required.

PROC GMAP MAP=map-data-set
<DATA=response-data-set>
<ALL>
<ANNOTATE=Annotate-data-set>
<GOUT=<libref.>output-catalog>
<IMAGEMAP=output-data-set>;

Required Arguments

MAP=map-data-set

names a SAS map data set that contains the Cartesian coordinates for the boundary points of each map area. The map data set also must contain the same identification variable or variables as the response data set.

Options

PROC GMAP statement options affect all of the graphs that are produced by the procedure.

ALL

specifies that all maps generated by the procedure should include every map area from the map data set, even if the response data set does not include an observation for the map area. When ALL is used, the map areas that are not in the response data set are empty (no pattern fill) and are outlined in the foreground color. To change the outline color of an empty area, use the CEMPTY= option in the MAP statement.

If you omit this option, the GMAP procedure does not draw those map areas in the map data set that have no corresponding observations in the response data set. This is the default behavior.

When you use the ALL option with BY-group processing, the maps that are generated for each BY group include every map area from the map data set.
