I have a list of lat/lon points in a kml file which I would like to group into world regions. How can I use the World Borders Dataset or some other dataset to generate a "region" tag for each point?

if you can find a data which contains "region" column as administrative areas or boundries in polygon, you can union them in qgis. with this way you will get region parameter for all your point..

Vector > Geoprocessing Tools > Union

you will see the changes when you look at your attribute table..

union

i hope it helps you....

Sorry, but I'm not sure what you're suggesting here. I don't think you can Union two layers with different types of features. –  Micha May 17 '12 at 10:38
    
you are merging attributes not features. i am wonder whether trying or not? –  Aragon May 17 '12 at 10:49
    
I don't really understand your suggestion, and I'm also looking for a way to achieve this programmatically, is this possible with Quantum GIS? I've not used it before. –  Globalkeith May 21 '12 at 13:45
    
yes, it is possible with Quantum GIS and pls give detailed information in your que. you dont specify to achieve this programmatically that how can understand your needs. i hope it helps you.. –  Aragon May 21 '12 at 14:19
