Ranking the total coastline coverage by country, from highest to lowest.
Coastline Coverage is the complete coverage of land access to open deep water sources. Lengthy coastlines require a larger financial and material commitment concerning self-defense and, as a result, many nations have developed amphibious assault forces and specialized coastal patrol craft to minimize a concentrated attack from the sea. For the purpose of the GFP ranking, a lengthy coastline coverage requires a dedicated commitment to homeland defense and, as such, island nations are particularly vulnerable to invasion from the sea.
Land-locked nations, such as Austria, are not penalized for lacking a coastline.
