Summarize the following:
Some people are better at reading maps than others, and these people tend to also do better when given directions that are the verbal equivalent of looking at a map — called “survey perspective.” These are the kind of people who are good at “getting their bearings” and telling which way north is without a compass, and have a good “feel” for estimating that they just drove for two miles. In this case, your directions will sound like the following: “Drive north on Hamilton for a little over 3 miles (4.8 km), then head east on Church Street…” Include units of distance in every step of your directions. For example, specify how many miles or kilometers the person will stay on a specific road before turning or getting to their destination.  City blocks and highway exits are also an acceptable unit of distance to use, even though the exact distance between them varies: “Go two blocks north, then get on the freeway and head west to the fourth exit…” A rough estimate is better than not giving any sense of the distance from one point to another. While it’s always a good idea to mention whether something is on the right or left, you should also provide cardinal directions (north, south, east, and west) when you explain a route to someone in survey perspective. And even people who do better with route perspective (following landmarks) often have a vehicle or smartphone equipped with a digital compass, and many road signs (like U.S. interstates) indicate a cardinal direction. So: “Turn right at the the light onto 5th street and go south for half a mile, then merge onto route 35 South…” If you’re having trouble verbally communicating directions to someone who understands directions better in map format, just sketch out the route for them. A map will allow the person to visualize where they’re going. You’ll also be able to include details, such as the location of landmarks, on your map. In addition, the map will give the person something to hold on to so they don’t forget your directions. The rudimentary map doesn’t need to be to scale, but you should write in general mileages and use a general map orientation (that is, with north to the top).

Summary:
Create a mental map of the route, and share it. Specify distance from point to point. Refer to the cardinal directions. Draw a map.
