The renegade cartographer

Dave Imus challenges the murkiness of modern mapmaking.

"I wanted to express the basic geographical arrangement of the U.S.," Imus says. "What's the elevation of Denver, Colo., and of Minneapolis, Minn.?" Physical details like these shape everything about their locations -- life at 8,000 feet is very different from life at 80 -- which is why understanding them is so important, he says.

The field of cartography has undergone massive changes over the last few decades, moving from a labor-intensive process involving specialized drafting pens, sheets of Mylar and industrial-sized lights and cameras -- to one that's digital and software-driven. Imus produced his last hand-drawn map, of Oregon, in 1999. "You can go to the Brownsville Historical Museum and see the tools I was trained on," he says.

Now, computer technology makes the drafting process much easier, cheaper and faster and enables cartographers to devise increasingly sophisticated maps. They have access to loads of already-compiled geographic data and can make once-tedious revisions with a few clicks.

Despite this, the overall quality of mapping has declined, mapmakers say. Many mapmaking corporations don't allow their employees time to craft anything beyond the status quo. "An awful lot of what's called mapping now is really just data display -- just display the data and you're done," Allan says. "You've got to pay someone who knows the trade to spend a lot of time making it better, and it's the Walmart-ism of American life -- we don't want to spend that money."

Creating a map is a winnowing-out process for most cartographers. Imus, however, prefers to start like a painter, with a blank canvas. To create his U.S. map, he selected data points from a comprehensive digital file. First, he used a mouse to redraft coastlines, smoothing out detail that came across as gnarled when viewed at his 1:4,000,000 scale. Then he selected rivers, fine-tuning each and every bend. He added relief shading to indicate landforms, background colors to signal land cover and lines of varying thicknesses to mark boundaries.

Next, he chose the cities to include -- 10,000 from the 100,000 in his data file. Then he selected the 1,000 landmarks -- including Haight-Ashbury, the Arctic National Wildlife Refuge and the site of the Wounded Knee Massacre -- he felt most important to the country's culture and identity.

He placed each type label to ensure the lettering did not overlap anything important and excluded anything that compromised clarity, foregoing the town of Golden, Colo., for example, in favor of the Red Rocks Amphitheatre, and waiving some St. Louis suburbs for the Gateway Arch and Anheuser-Busch Brewing Company.

In a field dominated by algorithms, the presence of a person with a vision making educated decisions about which data points to include, and how, can mean the difference between a lackluster map and one that inspires awe, says Daniel Huffman, a cartographer and map critic in Madison, Wis. "Maps are spatial stories, not neutral collections of facts," he says. "Something that looks very lived in and very personal is what I appreciate most."

Geographical awareness connects us to the world and attunes us to other people's realities, equipping us to make better decisions about politics, economics and the environment. But above all, it's just plain fascinating. "Imagine your life without music," Imus says. "That's what I think people's lives are like without geography. They're missing a huge chunk of what's interesting and enriching."

Imus believes so strongly in promoting geographic awareness that he plunged $117,000 into debt over the two-year period he spent creating and printing his map. The public did not take notice, however, until January 2012, when a Slate article proclaimed his work "the greatest map of America you'll ever see." In the month following the article's appearance, Imus raked in half the money he's earned in his lifetime. ("That's not saying all that much," he qualifies.)

Nearly two years later, Imus estimates he's sold perhaps 35,000 maps. "I'm really convinced that the potential market has barely been scratched," he says.

Imus would like one of his next projects to be reference maps of each of the 50 states, something he estimates would cost $50 million. Also, he would like to get his U.S. map onto more walls -- which, given my own living room revelations, I think would benefit everyone.

"To me, something like the United States viewed at the distance of a map is the most colossal and elegant art that's ever been conceived," Imus says. "It's like a giant tapestry of interwoven elements, and if you pay attention, you're like, 'Oh my God, that's exquisite.' It's just thrilling that I'm somebody who gets to put it all out there and be like, 'Here it is folks -- this is the world we live in.'

Thanks for helping keep the art alive. As a fellow cartographer working for a large consulting firm (officially my title is GIS Analyst which I find unbearable) I understand the frustrations of producing a map with no soul. I miss the freedom of being able to spend time creating something visually appealing and useful.

Again, thanks for keeping the art and science of cartography alive! I'm a cartographer too, working in my own little shop, and while the independence is really fine, the economics of competing with the large corps is just devastating. Now with mapping going to the internet there is very little true cartography involved. Just data display supported by code programming. I was very heartened to see David Imus' maps and know that artistic cartography is still alive in the hearts of some.

Like botanical illustration, cartography is an identification art. Botanical illustration allows users to identify wonderful things like flowers, while cartography allows users to identify the dazzling patterns of the world in which we live. There is more to the art of expressing geographic patterns than most cartographic organizations have the budget to attend to, because like all good identification art, good cartography takes a lot of time to create. I am fortunate to have had the deep time needed to make maps to the best of my abilities. Thank you Christina and HCN for telling my story.

Another "GIS Analyst" here, but maps are my love. Thanks for keeping the beauty alive.

Wow, it is really good to read this story and to validate my belief that Cartography is very important . As a Geographer/GIS Analyst I often times run into conflict with my managers over time spent producing effective cartographic representations. Displaying data via mapping software is easy, producing meaningful maps that are clearly readable is not. Cheers to you Mr Imus!

Interesting that other cartographers are dominating this discussion... I too have my own home-based cartography company, Map Metrics, mapmet.com and do spend the time to move labels were they will work best and be readable from one direction. Still I think of maps as an index to time and geology and think the hyperlink is the quintessential artifact of the Internet age. Beautiful maps can be the beginning of an understanding of place populated by ties created by others who pay attention to where they are. Like other innovations bent to the corporate will, they can be awful, but there is a lot of potential to communicate beyond the surface of the map.

Even in a crisis, maps can take us to a different level of information. Exceptional map maker Evelyn Backman Phillips produced amazing maps of wild land fires that threatened the Wood River Valley (Sun Valley) Idaho. The most recent was the Castle Rock Fire this summer. Although inciweb, the government site, had a map, it could not compare to Evelyn's for details about fire involvement for the beloved canyons, rivers, trails, and the Sun Valley ski mountain itself. The map is available online at the site of the Idaho Mountain Express, where she published updates throughout the fire. Mr. Imus map will join our collection not only because of its beauty and information, but because talent like his and Ms. Phillips needs to be noticed and nurtured!
