Greetings
I'm doing a small tool to calculate distances between cities. I mean, I
enter City of origin geographic position and city of destination
geographic position and I calculate distances. The thing is, everytime I
have to check at GOOGLE Earth a city position and it's getting to be a
long a heavy task to do.
I realized that, this guys
http://www.assemblysys.com/dataservices/db_details.php?db=3 are
distributing a database with cities geographic positions but this is
PAID :( . What I wanted to know is if there is any
tool/software/database free, open source where I can do exacly the same
without having to pay for that. And even, maybe add a few cities
positions and contribute to the project
http://www.openstreetmap.org/
Also http://geonames.org
Which has an API and downloadable database of placenames.
