I have a map of Australian postal codes (technically a postal code shapefile downloaded from the Australian Bureau of Statistics (ABS) Web Site) and I want to use this map to construct a higher level map using proc gmap in SAS.
For example, a number of postal regions will form a larger region and I only want to show this larger region.
Is this possible?
The reason I need to do this is that the ABS does not provide a map for this higher level region and so I need to do this myself.
Of course, this is possible in MapInfo, but I want to do it in SAS.
