This is probably an obvious question.
I have an Australia Shapefile (can be found here http://www.abs.gov.au/AUSSTATS/abs@.nsf/DetailsPage/1259.0.30.001July%202011?OpenDocument) and some custom data which contains latitudes and longitudes for a number of people.
How can I join the shape file to the custom data using latitude and longitude so that I can create a population distribution map and colour the segments of the map accordingly?
Thank you.
