How do cartographers (map-makers) deal with changes in landscapes over time that make their maps obsolete? Atlas Obscura has an interesting story this week on what cartographers do to deal with changes in Arctic sea ice maps as well as changes in coastlines caused by rising sea levels and warmer oceans. Of course other things like revolutions that cause changes in the names of countries and human endeavors like dam-building also cause changes in maps, but cartographers are trying to make their maps relevant for longer time periods than in the past. You can read the story here.
