Using Color in Maps

Using Color in Maps
Using Color in Maps 1 - Plan on Purpose Before you select colors for your map, it is important to understand who will be reading it, and how it will be used. In the following steps, you will choose an appropriate color scheme and then a color palette to best communicate the information you are trying to convey to the reader from the data included in your map. Particular color dimensions suggest particular characteristics of your data. Color hue suggests qualitative differences, color value ordered, quantitative differences. These guidelines apply to point, line, and area map symbols (Krygier 2011). 2 - Choose A Color Scheme START Does map show ranked data? Qualitative Scheme Favorite Pie — Cherry ---Lemon — Boysenberry — Sweet Potato — Pistachio — Blueberry Does the ranking have a “center” or “middle”? NO Sequential Scheme Poverty Rate (%) ----50 or more — 40-49 — 30-39 — 20-29 — 10-19 --- less than 10 Do the data values trend inward? YES--> Converging Scheme black: mystery, strength, heaviness

Projections and Distortion in the News A colleague today brought in a newspaper clipping from the weekend edition of the Wall Street Journal for 13-14 April, 2013. It was a map depicting the extimated range of North Korea’s Musudan missile. A couple of things were immediately interesting about this. How The Rainbow Color Map Misleads Colors are perhaps the visual property that people most often misuse in visualization without being aware of it. Variations of the rainbow colormap are very popular, and at the same time the most problematic and misleading. The rainbow color map is based on the colors in the light spectrum, and is sometimes done correctly, sometimes the colors are in the wrong order. Quick, name the colors in the rainbow in order!

Map design: a list of helpful online resources Whether they’ve been making maps for 20 years or two weeks, just like any designer, cartographers need inspiration when starting their latest project. Inspiration can come from many places and take many forms. Here at Ordnance Survey we use a range of resources and we want to share some of them with you.

Map coloring Map coloring is the act of assigning different colors to different features on a map. There are two very different uses of this term. The first is in cartography, choosing the colors to be used when producing a map. The second is in mathematics, where the problem is to determine the minimum number of colors needed to color a map so that no two adjacent features have the same color.

The Map Academy › Design for Beginners › Lesson 2 Ugly maps, like the one we showed you at the end of the last lesson, are not hard to find. You can probably think of several maps you’ve seen that make you cringe. At the same time, you can likely think of many beautiful maps. Our Favorite Maps of 2013 The digital maps we loved in 2013 didn't simply illustrate novel or useful information (how people travel, where they live, what it means to live without much money). They did it in ways we'd never seen before, manipulating time, dimensions, perspective, even the atmosphere. These maps weren't just interesting in content; they were innovative in design. That's our new bar for 2014.

Color Theory and Mapping Originally published by Miranda Mulligan, executive director of Northwestern University Knight Lab, and formerly design director for digital at the Boston Globe, on Source under a Creative Commons Attribution 3.0 licence. Of all the forms of non-verbal communication, the most instantaneous method of conveying messages and meaning through visual cues is color. In our design work, we use white space, typography and color theory to create and support the information architecture of a composition or a story. Information layering—organizing large amounts of data into short, digestible chunks—is a method for providing multiple points of entry into a story package, presentation, or layout.

Favourite maps from 2013 Everyone and their dog tends to publish their own 'best maps of...'. Given I spend most of my time on this blog haranguing bad maps during the year I thought I might try it myself this year so here goes, in no particular favourite 10 maps of 2013. For those that are counting, there's 11 but here goes... NYCHenge by Andrew Hill Ten Things to Consider When Making a Map What makes a good map? When done well, a map is a vehicle for effective communication. There are many cartographic principles to help guide effective map making.
