GeoNames

"The GeoNames geographical database is available for download free of charge under a creative commons attribution license. It contains over 10 million geographical names and consists of over 9 million unique features whereof 2.8 million populated places and 5.5 million alternate names. All features are categorized into one out of nine feature classes and further subcategorized into one out of 645 feature codes. (...) The data is accessible free of charge through a number of webservices and a daily database export.

Place Name Authority List

"The Places name authority list (NAL) or Common Authority Table (CAT) is a controlled vocabulary listing locations relevant for the descriptive metadata used at the Publications Office and the core metadata used in the data exchange between the institutions involved in the legal decision making process. This NAL is maintained by the Publications Office of the EU in its Metadata Registry (MDR)."

Earth Observation Thesaurus

"The project aims at developing a controlled and structured terminology system related to GIS and remote sensing. The first phase corresponds to the identification of potential sources of terminology, the selection of proper terms, their extraction and the creation of a terminology database. Terms have been classified according to the EARTh upper structure. The semantic classification foresees the allocation of each term in a relation tree starting from the more general concept represented by the category. The result is a terminology system containing about 3.500 terms.
