Sample 56332: Annotate points on a U.S. map using the MAPSGFK.US_STATES data set
The sample code on the Full Code tab illustrates how to use an annotate data set to place points on a map using the MAPSGFK.US_STATES map data set. The PARMIN and PARMENTRY options are used in the PROC GPROJECT statement to project the annotate data set to match the MAPSGFK.US_STATES data set.
