What is the sci-fi map editor?
The sci-fi map editor is a JDR Ninja tool for drawing science-fiction location maps: ship decks, orbital stations, outposts, underground complexes. You draw rooms, link them with corridors, place symbols (airlocks, consoles, reactors, weaponry) and annotate each room.
A map can contain several decks: each deck or floor has its own plan, reachable through tabs. The snap grid aligns everything cleanly, and an optional sub-grid lets you place details at a quarter of a cell.
When your plan is ready, you export it as an image at the right cell size for your virtual tabletop: Roll20, Foundry, D&D Beyond, Owlbear, Fantasy Grounds. Your maps are yours: use them in play, share them or sell them without restriction.
Draw freely
Rectangles, polygons, circles or free shapes for rooms; straight, angled or curved corridors to link them. The snap grid keeps everything aligned.
Multiple decks
A ship has several decks, a station several floors. Each deck has its own plan; switch between tabs and export them separately.
Ready for your VTT
Export to PNG, JPEG or WebP at your table's cell size: Roll20, Foundry, D&D Beyond, Owlbear. Import the image as a map background and it is ready to play.
