Something nautical
Ever wonder wonder what a raster chart was? Yeah me neither. How about how mariners navigate the waters? They use radar, right? Well, that’s just to see what’s around you so you don’t hit anyone. How do you know where you’re going when there are no roadsigns? You use charts. They’re like roadmaps of the ocean based on latitude and longitude instead of landmarks. The electronic version of this is a raster chart. Relying on Marine VHF is much better than getting lost at sea, that’s for sure!
