Best Options for Maps in SAS 9.2

Is there a better way to display maps and the concentration of population in SAS 9.2 than to use proc gmap?  This documentation covers gmap http://support.sas.com/sassamples/graphgallery/PROC_GMAP.html

It is very simple to display counties. 

data va; set maps.counties;  if (state=51) then output; run;  /*Subset VA*/

proc gproject data=va out=VAprj; id state; run;

proc gmap data=VAprj map=VAprj; id county; choro county; run;

You will need to change the DATA variable in GMAP to whatever you want.

Note, i wouldn't display counties for the US map because it will be too cluttered.

Also note that MAPSGFK are better maps to use if you are running 9.4.  But you cannot use them with 9.2.

Are you looking for US maps?

There were some neat maps floating around the past month or two that use a hexagon representation of the data - it uses lat/long as X/Y so not a geographical representation but it was in the shape of US and illustrated the data quite well.

I’m looking for three maps, US, Virginia, and Global.


Can you post the link?

This is useful.  I’m not sure how to display counties on the state map though.
