I was searching for a list of neighboring/bordering/adjacent states for each USA state.
I asked on StackOverflow but I had no luck: http://stackoverflow.com/questions/12402673/get-the-neighboring-states-of-a-given-usa-state
I wasn’t able to find any open data.
So, I finally decided to create my own list using the following sources:
=> Feel free to verify, contribute and reuse my file: neighbors-states.csv
- The SQL script was created for SQL Server 2008.
- Add a column called “IsApproximativeNeighbor” in the table “NeighborStates” to define properly the relation between Alaska and Washington state even if there is no common border.
- At first, I wanted to use MySQL but I discovered that MySQL constraint implementation still is incomplete: “the CHECK clause is parsed but ignored by all storage engines”. See http://bugs.mysql.com/bug.php?id=3464 and http://dev.mysql.com/doc/refman/5.1/en/create-table.html.
- Maybe some of you remember the song from this cartoon: Animaniacs video of Wakko’s famous 50 State Capitols song.
- By the way, I never been to the USA and this list give some motivation to visit USA!
