GeoNames is massive geographical database that contains "over 10 million geographical names and consists of over 9 million unique features". GeoNames integrates geographical data with place names in various languages, physical features (area, elevation, longitude/latitude), and social statistics (population, currency, postal codes, national flag). GeoNames is a collaborative project that encourages user participation by allowing users to "manually edit, correct and add new names using a user friendly wiki interface". GeoNames is a worldwide initiative that is managed and maintained by ambassadors around the globe who lend their help and expertise to the project's development.
