Countries by Coastline

Which countries have the longest coastline? Wikipedia has two separate sources both of which I believe to be flawed. I decided to create my own list, which I believe to be the most accurate currently available on the internet.

Methodology

This is based on original research by me, the JetPunk quizmaster. I wrote a script to calculate the coastline of each country based on this original data source from Natural Earth.

Notes

  • This does not include lakeshore
  • It does, however, include oceanic seas and inlets such as the Black Sea, Mediterranean Sea, Puget Sound, etc..
  • It does not include the Caspian Sea
  • The coastline for Israel does not include Gaza
  • The coastline for each country includes overseas regions, dependencies, and autonomous areas. For example, the number for Denmark includes Greenland.
  • 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

Wow! I wish I knew how to do such scripts... can you calculate the length of lake shorelines of each country?!

It looks like the numbers are downgraded compared to the usual numbers. Local info is of course pretty much useless for comparison, so just as curiosity:
Croatian sources say 526 km in a straight line, 1777 along the mainland coast and 5835 km with islands (74% of Adriatic coast)
Slovenia is usually given between 42 and 48, most often as 46.6 km. Especially when it's so small, it's easy to look at a detailed map or satelite photo and wonder why this bay or that wouldn't be included – in this blog you can see an image illustrating how you can arrive at different values. Further complicated (at this scale) by the port piers/docks and salt ponds.

This list is not perfect, that's for sure. But I trust the data since I know where it came from. Other lists seem like they draw data from different sources that use different methodologies.

If you look at this list: https://web.archive.org/web/20120419075053/http://earthtrends.wri.org/text/coastal-marine/variable-61.html you will see that they do not draw data from different sources that use different methodologies, which you will find out if you check their technical notes.

This appears to be an archived version of a low-authority site that appears at first glance to have the same data as the World Factbook and references a 1989 U.S. military map with no notes on how the shoreline was calculated. But, wait, it's not the same as the World Factbook. Check Denmark, for example. We still have no idea how the World Factbook gets its numbers.
