The Place-Names of America
John Nelson recently noticed that navigable passages between mountains in the USA have lots of different names. Some are called passes, others are called gaps and some are even called notches, or saddles. Being a cartographer John wondered whether there could be any regional variation in the use of these names for navigable valleys. He therefore mapped out where these place-names are used in the USA and released the results in the Gap, Pass, Notch and Saddle story map.
To examine the regional variations in the words given to navigable valleys in the USA Nelson downloaded and mapped every named place from the U.S. Board of Geographic Names. The result is a fascinating map of 2.3 million place-names in America. As you scroll through the Gap, Pass, Notch and Saddle story map you are shown how place-names in the USA concentrate where humans settle along coastlines, along transportation routes and in major conurbations.
As you progress further though the Gap, Pass, Notch and Saddle story map the non-valley place-names are removed from the map. The different navigable passage place-names are then each given a different color. The result is a map which reveals the regional variations in how these passages are named throughout the USA.
If you are interested in carrying out your own toponym research John has included a link to download the huge place-name database from the U.S. Board of Geographic Names. Alternatively you could be lazy and play with Places! instead.
Places! allows you to map the relative density of place-names in different countries around the world. Using the application you can enter place-name prefixes or suffixes and view a map showing the geographic distribution of place-names containing those terms.
For example, in the USA we can enter the prefix of -Las to see where towns and cities have names starting with the Spanish word for 'the'. In the UK we can view where place-names include the suffixes -thorpe and -thwaite to see where the Vikings settled in Britain (the resulting map shows that these two place-name endings are popular throughout the area that was once known as the Danelaw, following the Viking invasions of the ninth century).
The Places! application uses OpenStreetMap for the place-name data. The application includes a number of options which allow you to adjust the size of map, circle points and an 'advanced' option which allows you to carry out 'regular expression' searches.
You can have hours of fun with Places! For example in the USA if you are interested in where Spanish plays a large part in local place-names you could also search for the distribution of the San- or Santa- prefixes. On the other hand the suffix -ville might be a good indication of where French immigrants originally settled in the USA.
