Meet Purple Lizard

Purple Lizard Maps is an independent cartographic design firm dedicated to making beautiful maps of special places for people who love the outdoors. We have been publishing our unique brand of maps since 1997.

The Mission

Creating extraordinary maps for people who love to explore the outdoors is our passion, our mission and our reason for being.

How We do What We Do

Many people ask if our maps are made from the internet, as if the internet is something we can pick up and work with. 

Purple Lizard is not an armchair map company. Our approach blends the best aspects of old world map making with all the advantages of high tech data. We immerse ourselves in the landscapes and communities we map. We gather information from all sources and sort out what's true and what's not, carefully selecting the information that our users, outdoor recreation enthusiasts of all types, are seeking. The result is a highly curated map tailored to outdoor adventure, and one we consider to be the best map we can make.

Our immersive approach allows us to create maps that are exceptionally curated and beautifully designed, offering users the perfect level and type of detail for their outdoor adventures. This approach also allows us to connect with and learn from the people living and working in the communities we map. We don't focus on any single type of outdoor recreation, so our maps show all the options in an area that are open for public access - by foot, bike, horse, motor, air or water. The end result of our mapmaking process: The most detailed and beautifully designed outdoor recreation map ever produced of that region.

Our commitment to ground-truthing and real-world map making allows our customers to really explore the forest and communities we map in a way that creates a connection to the place. We care about the communities and the landscapes. Purple Lizard believes in protecting and preserving public lands and beautiful natural environments. We are a member of 1% for the Planet, and we work with environmental non-profits within the communities we map to support preservation efforts, trail building, river clean-up efforts, trailhead access improvement, interpretive media projects and other needs on a very local level.

We are trail users, backpackers, mountain bikers, history buffs, environmentalists and map makers. We are Purple Lizard, and we are not like any map company you've ever met. 

Where We Map

Purple Lizard was born in the mountains of Central Pennsylvania, but has grown a lot since then. We publish maps of Pennsylvania, West Virginia, Ohio and Puerto Rico.

Michael Hermann: Lead Cartographer and Founder 

Purple Lizard Maps was founded in 1997 by award-winning cartographer, Michael Hermann, with a mission to push the boundaries of modern recreational map design and publish beautiful trail maps to help people make their own adventures.

Michael received his B.A. in Geography from Penn State with a focus on digital cartography and launched his career as a Digital Cartographic Specialist with Trails Illustrated/National Geographic Maps in Colorado. Today, Michael is among the leading cartographers in the industry. He has received numerous design awards from the American Congress on Surveying and Mapping and the Cartography and Geographic Information Society. In addition to his work with Purple Lizard, Michael served as the lead cartographer with the Canadian-American Center at the University of Maine where he led the development of the award winning Historic Atlas of Maine. That atlas received the Globe Book Award for Public Understanding of Geography and Best Atlas of 2016 from CaGIS. Michael is a past president of NACIS (North American Cartography and Information Society) and past president of the Osher Map Library and Smith Center for Cartographic Education at the University of Southern Maine. Purple Lizard gets their hands in a few other projects as well - they mapped out the first IMBA Epic Mountain Bike course in Pennsylvania in the 1990s; they design and produce the Maine Appalachian Trail Maps, and they produce maps for the Leadville 100 Race Series in Colorado.

Lizard Contributors 

Purple Lizard Cartographic Contributors include a small group of some of the best cartographers and adventurers anywhere who share our passion for exploring the outdoors. Below is a bit of info about some of our regular contributors who work with us on special assignments to help bring Purple Lizard's Maps to life.

Erin Greb of Erin Greb Cartography has always had a close connection to the outdoors and exploring. Growing up with acres of woods in her backyard in western Maryland and driving cross-country every year with her family on vacations, maps always played an important part in her life.

Erin Greb Cartographer

As a second year art major who loved to hike in the mountains near Penn State, the lightbulb went off one day that she should transfer into Geography (’99) and learn to make maps like the ones she used in the woods (including the original Rothrock Purple Lizard map!). She then earned her MA in Geography at CU Boulder (’02) where she continued to hike and mountain bike in the foothills and Rocky Mountains. Now she continues to explore and design maps and enjoys traveling around the country for trail races. 


Dave Gantz: Trail Guru

Dave Gantz: Purple Lizard Maps Trail Guru

Dave Gantz does more than his fair share of hiking - see to get a sense of what he does or where he may be headed. Dave’s main passion and his goal in his work are to introduce and reconnect people with the natural world.

Dave has done a lot of on-the-ground recon for Purple Lizard to help figure out what is really there and how the trail systems come together.
