  1. /Transform/Recode into same variable. Select your factor or other variables, recode missing data to -99.
  2. Use /Graphs/Legacy drawings/Scatter Dot/Simple Scatter/Define. Then make Latitude the Y axis and Longitude the X axis, and put your map variable (binned or low-integer variable) in the "Set markers by" window.
  3. Double left click the legend element "-99" and a new window will open with the graph. Then click "-99" again. Click "Properties" (or in some cases "Markers"). Reduce the size to 1. Close this window.
  4. Repeat for each specific value (1,2,3,4) this time under "Properties" and "Markers" change the fill color so that the colors contrast to mark out what you want.

There may eventually be another way to do step one once the problem with Spss 16 is fixed, as documented in http://www.spssforum.com/viewtopic.php?p=4677&sid=9221325dfc5fbfa53a53efeb1939deab
