The best maps are still to come, and you’re going to make them.
Mapmaking requires no formal training or credentials. I learned by trial and so will you.
The best contemporary mapmakers taught themselves: Eleanor Lutz is a bio PhD and learned cartography on her own. Illustrator Mike Hall sketched maps in his notebook during shifts as a security guard, and now has an agent to handle his map deals. Alex McPhee studied geophysics, decided he needed to map his native Alberta, got some open source geo-software and made one of the best modern reference maps.
Cartography is like cooking: you pick what you like to eat, and improve by trial. You’ll over-salt a few dishes, ruin a few pans and come out a master. You just have to pick some Territory to commemorate.
Just draw one!
Cartography is making the infinite Territory legible to humans, which gives you many ways to get to the same point.
Find some Territory you care about: your yard, your street, your neighborhood, your town, your favorite patch of woods. Get a pencil and paper. Mark what you care about. You’re now a cartographer. If you stopped reading and drew a map on a paper towel, I’d be satisfied.
You can make a map with charcoals and an easel, a stick and some sand, a pencil and graph paper, a grid computing cluster, some hideously expensive software, some there’s-no-way-this-is-free software, a drone with a camera, a satellite with a radiometer, all ways to the same end. There’s no “correct” way to make a high-effort map.
If you still want to use the computer to make a nice-looking map, read on.
I learned cartography at close range from Daniel Huffman. if possible close this tab, get a desk next to a cartographer, pester with questions for 1+ year.
Every cartographer has their own idiosyncratic way of making maps; this is only what I can get my head around. If this doesn’t work for you please check out other ’tographer tutorials at the bottom, they might click better.
My entire toolkit:
⓿ Getting started
Here’s my map workflow, you’ll find yours soon enough:
▼ There’s a big directory of links at the bottom of this page; if you need data, a tutorial, some inspo, check down there first. ▼
❶ Install some free software
Install click-around map software
QGIS – download QGIS, an open source geographic program. Lets you manipulate geodata with relative ease and export an SVG/PDF to cute up in Illustrator.
QGIS tutorial 1 – getting started with QGIS.
QGIS tutorial 2 – more QGIS tutorials.
Install type-around map software
You’re gonna install GDAL (Geospatial Data Abstraction Library), a command-line tool that lets you edit geodata without clicking around in QGIS. Learning to type your way through changing projections, cropping images, filtering data etc. will greatly speed up your mapping. It might feel awkward at first but it’s very useful; I hate coding and I still love command-line tools.
Using a Mac?
❷ Find some geographic data
You’ll encounter dozens of arcane file types but here are the main ones to look out for. All of these get worked over in QGIS and GDAL.
Where to get geographic data
Need something else? Time to start sifting the resources page down there ▼.
❸ Design your map
So now you have QGIS and GDAL installed, plus a folder full of geographic data. How do you turn that into a map? Someday you’ll get an end-to-end account (it’d take like 30,000 words and good screencasts) but for now you join the grand tradition of “follow a tutorial (check the resources pile at the bottom of this page ▼), ask your computer pals at The Spatial Community for help when you get stuck.”
For now, some general guidelines:
Reproject your data
Whatever coordinate system you project your data into, you gotta apply that same projection to all the other data in your map. It’s all gotta match!
Vector data is easy to reproject in QGIS. Raster stuff like imagery and elevation data is a bit more involved:
Make the terrain
Once your data’s cleaned up and you’re left with what you want to show on your map, you export an SVG/PDF out of QGIS and make your vectors look nice in Illustrator or Inkscape. For the rasters (e.g. terrain and satellite imagery) export a TIFF from QGIS/GDAL and edit them in Photoshop or GIMP. There are tools that make this more convenient, like the wildly expensive MAPublisher plugin for Illustrator, but they’re not necessary.
Find some maps you like and see how close you can get; I think of ’tography as more craft than art, so you can get real far by copying the masters. Raid the inspo column down there ▼.
Now you’re in the art zone: compositing in Illustrator, labeling, futzing with colors, upsetting back-tracks to your original geodata, adding cute ephemera like north arrows and legends, illustrations. Make it look nice. Real nice. I can’t wait to see your map ♡.
