Geonames is a geographical database with web services that let users extract useful information about different places, such as weather, timezone and post codes. The GeoNames geographical database covers all countries and contains over eight million placenames that are available for download free of charge. Users can edit, correct and add new names using a wiki interface.
Geonames provides a suite of 36 Webservices covering the following categories:
The APIs use RESTful protocol and responses vary in format between XML, JSON, RDF, CSV, TXT, RSS and KML.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
