I guess I also need a database of the cities coordinates. Where could
I find one?
You can download US data here:
http://geonames.usgs.gov/domestic/download_data.htm
These are tables of geo entities with a number of columns, including
lat/long. NGA (formerly NIMA) has similar data for non-US entities:
http://earth-info.nga.mil/gns/html/cntry_files.html
Note that these data sets include =lots= of entities, not just cities -
we've combined them into a DB with about 6 million items, and only
about 2.5 million are population centers (by our scheme). Each of the
data sets has feature type columns that you can filter on, though.
