Identifies the
variable or variables in the input data set(s)
that define map areas.
Requirements: |
At least one id-variable or geo-variable is required.
|
ID id-variable(s) | geo-variable;
|
-
id-variable(s)
-
identifies one or more variables in the
map and response data sets that define map area. This argument is used only
when map and response data sets are specified. If a feature table is specified,
then specify a geo-variable instead.
Every variable that is listed in the ID statement must
appear in both the map and response data sets. The variable identified by
the id-variable(s) argument can be of type numeric
or character and should have the same name, type, and length in both the response
and map data sets.
Note: If the ID variables in the response data set and map data set
do not have the same length, then your map areas might not be drawn correctly. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
-
geo-variable
-
identifies the $GEOREF formatted variable
in the feature table containing the spatial geometry information for the map.
The variable identified by the geo-variable argument
must be of character type.
