Welcome to Map Practical, where the cartography gets done. These are the cartographic trenches, the domain of greasy hands, busted knuckles, and sore mouse fingers. This is the home of techniques, tutorials, and tricks of all things map. Here’s how we do it;

Projecting Natural Earth Rasters

The folks over at Natural Earth Vector have created a great free resource for making maps at 1:10m, 1:50m, and 1:110 million scales. The beautiful natural color reliefs generated by Tom Patterson, of the National Park Service, have been complimented with a set of vector data that cover the entire globe. Nathaniel Von Kelso, of the Washington Post, has created world coverages of rivers, cities, borders, and much more. While the vector layers are ready to go, the raster layers require projection before they will align in the GIS. It’s a simple process outlined here in a lab from my Intro to Cartography class. Once the geographic coordinate system is set, the data can be reprojected to your heart’s desire from within the Data Frame, all at within a few clicks. Check it out!
