MapEX Studio
A local-first planning workspace for turning GTFS rail networks into editable, compiler-backed schematic maps.
Overview
MapEX Studio is a private Electron and React planner built around the existing Python MapEX compiler. The compiler turns GTFS inputs into schematic rail maps; the Studio makes that process visible and editable without introducing a second generation pipeline.
The workspace keeps one authoritative MapSpec and one displayed MapEX SVG, so the planner and the rendered artifact remain aligned.
Core workflow
- Use the Build surface to run the existing GTFS-to-rail-map compiler and inspect its progress.
- Use the Map surface to work with the generated system map through its authoritative MapSpec.
- Make undoable edits while preserving a single displayed SVG as the visual source of truth.
- Render edits with
mapex render-specinstead of rerunning GTFS generation.
Current verification
Current checks cover the typed application build and tests, generation from a real WMATA GTFS feed, and rendering from MapSpec. These checks support the integrated workflow, but they are not evidence of uniform behavior across every transit system; feed-specific validation remains ongoing.
