Distance measurement tools indicate how far map elements are apart. In this video, learn how to enhance map analysis using distance measurement tools.
- [Narrator] Businesses often deliver products to customers in cities, so minimizing the distance their drivers have to travel can save significant amounts of money every year. In this movie, I will show you how to visualize the number of locations within a given distance from a central point, which could be a warehouse, bakery, or other facility. My sample file is 1203 distance and you can find it in the chapter 12 folder of the exercise files collection. In my visualization I have a map that shows a variety of locations in and around the Washington, D.C. area, so the idea is that my warehouse location is here. That's zip code 20918, and I want to find the radius of the circle between this point and the farthest point, which appears to be here, up near Baltimore. To do that I hover my mouse pointer over the map and then I have my toolbar, vertical toolbar that appears here. I'll point to the rightward pointing triangle and then click the radial selection tool. I want to find the radius of the circle from this mark here, 20918. If I were to click and drag while I had my mouse pointer directly on that mark, then it would change its position. So instead I want to move it so we're just slightly to the side and then start dragging, and you can see that I have a circle with a radius measurement that is appearing on my map, so I'm going to drag until we are right at the circle on the outside, the farthest one away of this group and I see that the radius of the circle there is 28 miles. If I want to find the distance to the second point, the second farthest which is in the opposite direction, then I can drag down and I can see it's 17 miles. When I release the left mouse button, you see that the items below are still selected. When I click away, everything in the visualization comes back. Don't worry, if you are following along and you didn't see the distance measurement circle the same way that I did. Whether it appears or not depends on the zoom level of your map and also the resolution and size of your display. That also means if you planned on using that tool as part of a presentation, make sure you practice on the equipment you'll be using at the same settings so that you'll be certain it will work.
