GeoNames is a free and open source geographical database. Primarily for developers wanting to integrate the project into web services and applications, it integrates world-wide geographical data including names of places in various languages, elevation, population, and all latitude / longitude coordinates. Users are able to manually edit, correct and add new names with a user-friendly wiki interface. The data is accessible through a number of webservices and a daily database export.

Autodesk recently announced plans to donate its coordinate system (CS) and map projection technology to the Open Source Geospatial Foundation (OSGeo). The software, acquired from Mentor Software will help users to more easily support geographic coordinate conversions and allow accurate and precise geospatial analysis. This planned donation joins several previous Open Source donations by the company, including the web mapping MapGuide and the geospatial data access technology (FDO) software, both donated last year.
