I am very new to ArcGIS and have the following question: I have a shapefile with around 1500 regions worldwide and want to calculate for each region the (average) distance up to the coastline of its own country (or if the country has no access to the ocean, the nearest coastline).
I thought about creating national coastlines (I have a shapefile with worldwide coastlines, however, they are not country-specific) and then calculate the respective distances to these line segments.
Would that work? And if so, how can I create national coastlines?
Thanks for your help :-)
