Why can't I open GeoNames documents and document-links in Safari browser?

By default Safari blocks Pop-up windows. Go to Settings, Safari, and uncheck Block Pop-ups. Refresh the GNSHome website in Safari.

When I open .csv geographic names files in Excel, the characters aren't rendering correctly. How do I fix that?

The .csv files are generated with UTF-8 character encoding, but unfortunately, Excel doesn't always recognize that encoding by default (this varies by Excel version and your own personal settings). To fix the issues, you need to import the .csv into Excel and specify that UTF-8 encoding is used. Open Excel. Import the .csv data using Data –> From Text/CSV and click Import. On the Import options window that appears, be sure to specify the File Origin field as Unicode (UTF-8) before choosing to load data.

Why do certain points/features appear to be gridded?

From the initiation of foreign geographic names collection in 1947 through the introduction of GIS in 1993, locations of named features were collected according to the gazetteer standard, which is to the nearest minute of latitude and longitude. This was the required accuracy level for the production of gazetteers.

The filter by visible extent option in the search application isn't giving me the "right" number of records.

Visible Extent is the map-area NOT covered by Attribute Table and Geographic Names Search controls. Sometimes one might have to zoom-in or zoom-out to see the entire collection of features in the application.

Why do some features have more than one name associated with them, and which one should I use?

Many countries have two or more official languages. These languages may be official nationwide or only in certain areas. We collect names in all official languages whenever possible. In addition, some features may have a conventional name in addition to an approved name. In these cases both the conventional and approved name are equally correct and either or both may be used.
