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..
you will see the changes when you look at your attribute table..
i hope it helps you....
