[Qgis-us-user] I am a beginner GIS person....HELP

[Randal Hale]

So there's one other way to tackle this - and I guess that depends on 
your data.

**IF** the areas have a field for Disaster Preparedness training - as in 
you open the attribute table for your data and you have a "training" 
column and in that column there is a "yes" or "true" - you can symbolize 
the data on that field. Which would sorta make your "selection" somewhat 
permanent.

Which may not make sense....Could you share a copy of your data? That 
might help. You're almost there it sounds like. You could send it over 
email just to me and tim or share it through dropbox. We'll delete it 
when done!

Randy
