The new Geonames Tools toolbox is available for download from Arcgis.com. The Geonames Tools toolbox is an Esri Defense toolbox for intelligence analysis. The zip file contains the tools and a template geodatabase with the schema needed to create a gazetteer style locator from National Geospatial-Intelligence Agency (NGA) UTF-8 encoded tab-delimited geonames text files.
The package includes two tools, with supporting scripts, and instructions for using the tools to create your geonames gazetteer locator. The first tool loads data from a UTF-8 encoded, tab-delimited geonames text files into a feature class, updating the Admin, Country, and Feature codes in the process. The second tool creates a gazetteer style locator from the feature class. This locator can be used on a local machine, or published via ArcGIS for Server for use by multiple clients.
This toolbox is designed to work with the files from NGA, available at:
Geoname files from other sources with different formats are not supported.
