/*
Importing Nacogdoches county Texas into something sas/graph gmap can use ...

Run sas in DMS mode
Type 'gis' in sas command window
File -> Build Census Tract Maps
In Geography tab:
Select state=texas, county=347 Nacodoches
Select ">" to move into "selected counties"
In Features tab:
Hilight 'Census Tract Boundaries' and move back to left "<"
Hilight 'Highways' and move to the right ">"
Hilight 'Rivers' and move to the right ">"
In Output tab:
Map Entries - sasuser, tgrmaps, nac
Spatial Data Entries - sasuser, nac
Click 'create' to generate the map.
Click 'ok'.
Click 'display' button.
Checkmark Highway, Rivers, and County.
Exit out of gis, and save the map.

Went to the following page
http://support.sas.com/rnd/datavisualization/mapsonline/html/tools.html
And downloaded gisexport.zip
Unzipped it into the current directory.

% unzip gisexport.zip

  inflating: Readmecpt.txt           
  inflating: ReadmeSAS.txt           

Then, in the same sas session, I run the gisexport.sas code with the
following settings/variables to create the sas/graph map dataset, 
and the annotate dataset (for roads and rivers) ...
