With 895,000 records and 1,115,000 names, the Getty Thesaurus Of Geographic Names Online lets you look up position and hierarchical data for geographic features around the world:

Lookup can be by name only, or limited by type of geographic location and nation; Boolean and wild-card operators are supported.

It’s a shame for geoinformation resource.
