US geographic names 2017-06-01

A text database of named places in the United States. <br>The US Board on Geographic Names controls the database of official names of places in the US, and the US Geological Survey (USGS) maintains the database. This is a copy of the 2017-06-01 database, which I am using to create an R package for textual analyses of geographic content, to ensure this version remains. The original source was from: https://geonames.usgs.gov/domestic/download_data.htm (which is a very slow server).<br>I have chosen CC0 for the license because, as a creation of the US government, I don't think the database can be copyrighted (and CC0 is the closest match).
