Maps and mappers of the 2020 calendar: Daniel Fourquet, July


Q: Tell us about yourself

A: For most of my life I have been fascinated with maps, both studying them and making them myself. As a child I would fill folders with detailed maps of an imaginary country and would spend too many hours playing games like SimCity and Civilization on the computer (ok, I do that as an adult sometimes too!). These interests would eventually lead me to studying geography at Old Dominion University in Norfolk, VA and begin a career doing GIS work. Recently I’ve become interested in programming and am now enrolled in the University of Wisconsin-Madison’s online GIS and web map programming masters program. I’m currently a GIS Analyst at the Virginia Department of Transportation in Richmond.

Q: Tell us the story behind your map (what inspired you to make it, what did you learn while making it, or any other aspects of the map or its creation you would like people to know).

A: I became interested in using 3D rendering software in cartography when I stumbled on some of the beautiful maps created by Owen Powell (@owenjpowell) last Spring. While doing research to learn how to make 3D maps of my own, I discovered the work of Daniel Huffman (@pinakographos) and Scott Reinhard (@scottreinhard), both of which were also influential. I experimented with terrain maps for a couple months before deciding to try creating an urban map using lidar data. I chose the US Capitol because it’s such a well known landmark.

My decision to design this map in black and white was inspired by Daniel Huffman’s NACIS talk ( about the challenges and advantages of mapping in monochrome. I initially planned on designing the map in color, but then I realized that removing color created a more formal tone that is fitting for a map of the buildings where such important decisions are made.


Q: Tell us about the tools, data, etc., you used to make the map

A: Data Used:

– The Lidar data was downloaded from the USGS National Map.

– I used land cover data from the Chesapeake Conservancy.

Tools Used:

– WhiteboxTools ( is a collection of GIS tools that allowed me to process the lidar data via Python to prepare it for rendering in Blender.

– ArcMap was used to organize and prepare the data.

– Blender was the 3D software used to render the Lidar data.

– GIMP was used to add the land cover data. I also manually brushed in the trees, which was time-consuming, but resulted in a much better map than relying on the trees from the land cover data.

– Illustrator was used for labelling and finishing the map. 


Maps and mappers of the 2020 GeoHipster calendar: Megan Gall, June


Q: Tell us about yourself.

 A: I started my career as a shovelbum, digging holes and mapping Fort Ancient Indian villages in West Virginia. We used survey equipment to inform the hand drawn maps, but one day I went into the office and someone had turned my hand drawn map into an image on a computer. My imagination caught fire. I’ve been a sociologist since I was 5 years old, noting and questioning patterns I saw in the ways humans behave and organize themselves. I knew that GIS would give me a foundational set of hard skills to build a career doing what interested me most — thinking about and studying group behavior. I looked for people who were using maps to study living people and current problems, and I found critical mentorship in them. 

Since then I’ve used spatial analytics to research and inform policy makers and non-profit groups on issues around homelessness, justice reform and crime, education inequality, housing discrimination, and historical predicates of current racial and ethnic inequality. I’ve been working in voting rights for years now. I draw maps for redistricting, but that’s only a sliver of what spatial folks can do in this field. I use spatial analyses to support the work of the civil rights lawyers ensuring compliance with the Voting Rights Act of 1965. I use the same types of analyses to support the work of advocates who want to understand voting and demographic patterns.

We need more spatially-minded people working on civil rights and social justice issues. This is a serious issue throughout the civil rights space but is particularly acute in voting rights. I invite folks who are either starting or re-inventing their careers to think about contributing their skills and considering this path. Please reach out to me via Twitter (@DocGallJr) if you want to explore ideas, ask questions about the nitty gritty of the work, or just chat about this type of spatial work. I’m always happy to talk shop.

Q: Tell us the story behind your map (what inspired you to make it, what did you learn while making it, or any other aspects of the map or its creation you would like people to know).

A: One day a friend asked me for a map of Prince shows. This was obviously a great idea. I’d used the final data set for several iterations of a Tableau viz (the latest, not quite done version here), but I also wanted to use these data for a static image because it presents new and interesting challenges for visualization. I’d been working with these data for years now, so this was a new take on how to use them. The GeoHipster calendar seemed like the perfect impetus and avenue for that goal.

Q: Tell us about the tools, data, etc., you used to make the map.

A: I originally consulted two unofficial tour listings from princetourhistory and princevault. I geocoded shows to the venue. When a venue address wasn’t available, I geocoded to the city – the only other geography I had. Because of that, I had to add some jitter to the mapped data. I used R programming and the tmap package, by Tennekes et al, for the final product. I initially tried to make the map with the ggplot2 package, by Wickham et al, but had more aesthetic control with tmap so switched over at some point in the creation process. Although I was trained in GUI based GISystems, I taught myself to code in R several years ago because it adheres to the notion of scientific reproducibility in ways that GUI GISystems can’t. This map took about 50 lines of code – fully reproducible. Again, an invite, I’d love to hash out the differences between ggplot2, tmap, leaflet, and other spatial packages in R. Please reach out if that sounds like a great time to you, too!


Update on the 2020 calendar

On November 26th, we at GeoHipster were informed of a dispute regarding potentially incomplete credits for one of the maps in our 2020 calendar. In the following days, we entered into discussions with the involved parties in an attempt to reach a satisfactory resolution. As a result of these discussions, on December 2nd we created a Second Edition of the 2020 calendar by substituting a map from Miguel Marques. Miguel’s map ranked highly among the original submissions, and will be included in all calendars ordered after our update. The Second Edition also includes an updated cover with Miguel’s name listed among the authors.

Please join us in congratulating Miguel for becoming part of this amazing product!

On #PostGIS Day, We Unveil Our 2020 Calendar

2020 GeoHipster Calendar

Let us here at GeoHipster be some of the first to wish all of you GeoJSON lovers out there a happy #PostGIS Day, just in case you don’t have our 2019 calendar to give you a handy reminder. And this year, we’ve actually had our act together well enough to be able to release our 2020 calendar to mark the occasion!

Support GeoHipster and independent publishers: Buy our calendar on Lulu.

If you absolutely can’t wait to get your own, the button above will take you to the calendar on Lulu. (Order by December 10 in the US if you want it by Christmas with regular shipping.) But, some of you are also wondering who the lucky map authors are! So without further ado, here are the amazing cartographers that have been selected for our 2020 calendar:

Congratulations to all the map authors! And, special thanks to everyone who submitted a map for our competition; you all made the voting very difficult! We’d also like to thank Bill Dollins for leading the charge on this effort, Jonah Adkins for the finishing touches, our Editorial Board for judging, and this year’s guest judges: Eben Dennis, Daniel Huffman, and Sophia Parafina.
