U.S. States by Coastline
Which states have the longest coastline? Until now, there has been no accurate source for state coastlines. Wikipedia has two separate lists, both of which are very inaccurate. I decided to make a better list.
Methodology
This is based on original research by me, the JetPunk quizmaster. I wrote a script to calculate the coastline of each state based on this original data source from Natural Earth.
Notes
- This does not include lakeshore
- It does, however, include oceanic inlets such as Puget Sound and Chesapeake Bay
- The length of coastline depends on the resolution of the data source. The higher the resolution, the longer the coastline.
- The source data is not 100% perfectly accurate but it, is in my opinion, the best data source available
