A vector-based illustration application is an absolute necessity for making professional-looking transit maps. I use Adobe Illustrator CC (2015), which is the choice of professional designers and map makers. If you can’t afford the hefty price tag of Adobe applications, many enthusiasts use Inkscape, an open-source (free) vector illustration application. It doesn’t have the same polish as Illustrator, and some of its functionality is implemented differently, but — from what I’ve heard — it’s a very competent editor. If you use a Mac, I’ve also heard good things about Affinity Designer, a newcomer to the graphic design and vector illustration world. At just $50 for a full licence (the same as just one month of an Adobe Creative Cloud subscription), it’s definitely worth checking out. Bitmap editors like Photoshop or MS Paint are really totally unsuited to the precise work required to make a transit map, and I really recommend you don’t even try. I offer lots of tips and tricks that I’ve picked up from making my own transit maps over the years on the site. Simply browse the “tutorial“ tag! Also, something I often recommend for people just getting started with transit map design is to find a PDF of a real map you like and open it up in Illustrator. Play around with it and see how it’s been put together. Sometimes official PDFs are password-secured against editing, but it’s worth a try! Sure! Send me a JPG of your map via the Submissions page (be sure to select “Photo” from the drop-down menu at the top left of the form) along with some details about it. Let me know if you want me to publish the map on the site or if you’d just like some private feedback. Be sure to add your email address if you want me to write back! I’ll admit that my scoring is totally subjective and probably inconsistent, but it’s generally a “gut feeling” score based on my own personal criteria, including, but not limited to: informational hierarchy, aesthetic qualities, technical excellence, uniqueness of the map, my mood that day and the phase of the moon. 0 = Absolutely no redeeming qualities. Technically deficient, difficult to understand or just plain hideous to look at. I started Transit Maps as a personal design exercise — to analyse maps from around the world and see what made them tick so that I could understand them more fully and make better maps myself. My reviews are simply my own opinion and you don’t have to agree with me — in fact, I encourage you to comment on the site and put forward your point of view. Every design problem has multiple solutions and some of them will appeal to some people more than others. Transit directions are beyond the scope of this site — try Google or the website of the transit agency you’re after. Source.
