If you’re like me, most-likely, you’re sheltering in place and doing your part to flatten the curve and keeping your loved ones, neighbors, and community healthy and safe. That comes with some downtime, and that downtime is the perfect moment to dabble in a cartography project! So, with that in mind, over the weekend, I put together another free brush set for you to use in your projects.

All my Map Tools will always be free. Want to help support this work?

This is Janssonius, a topographical brush set with a nautical flair based on Johannes Janssonius’ 1650 nautical chart of the Bay of Bengal, and I could see it being excellent for a wide variety of projects.

Often historical cartographers would use symbols familiar to their viewers no matter where a map was set. Hills and mountains were rendered similar in appearance to those at home. Here, however, Janssonius incorporated local floral and landforms giving his chart a more tropical flair. It sets the symbols on these charts apart from his contemporaries like Joan Blaeu, and it adds a nice touch to the overall map.

I can’t wait to see what you create. Before now, I haven’t based a set on nautical charts. So this round, I made sure to incorporate a whole host of maritime symbols—rocks, sounding marks, shallows, and a whole bunch more. This will be handy if you’re telling a tale set on the high seas or just want to add a flash of authenticity to the coasts of your maps. The full set has 275 brushes and includes the following:

  • 5 Individual Tents
  • 7 Grouped Tents
  • 25 Towns
  • 10 Cities
  • 6 Forts [Note: These could be symbols for mills, but taking into consideration the nature of the map, I believe they’re most likely fortifications.]
  • 25 Trees
  • 25 Palm Trees
  • 10 Palm Tree Groups
  • 8 Forests
  • 6 Fields
  • 20 Hills
  • 30 Mountains
  • 10 Mountain Ranges
  • 3 Anchorages
  • 2 Shipwrecks
  • 20 Rocks
  • 4 Shallows with Rocks
  • 10 Small Shallows
  • 5 Shallow Textures
  • 30 Sounding Marks
  • 5 People Cartouches
  • 3 Map Cartouches
  • 6 Ship Cartouches

The button below links to a ZIP file that contains a Photoshop brush set (it’ll also work in GIMP and with Affinity Photo) as well as a set of transparent PNGs in case you’re using a program that doesn’t support Adobe brush files. I’ve separated them by type: Settlements, Flora, & Landforms, and Nautical Symbols & Cartouches. They’re black, and they’ll look broken if viewed in Chrome, but trust me, they’re all there.


As with all of my previous brush sets, Janssonius is free for any use. I distribute my sets with a Creative Common, No Rights Reserved License (CC0), which means you can freely use this and any of my brushes in commercial work and distribute adaptations. (Details on this decision here.) No attribution is required. Easy peasy!

Enjoy Janssonius? Feel free to show me what you created by sending me an email or finding me on Twitter. I love seeing how these brushes get used, and I’d be happy to share your work with my readers. Let me see what you make!
