A roadbook editor for the desk

For a month the roadbook program has been building its foundations: a data model that carries the official FIM/FIA structure, an exporter that real rally readers accept, a symbol library drawn glyph by glyph, a print module measured off the FIA's own Diagram 1. Today the last and largest piece ships: a full roadbook editor in EpicRide, and with it the whole pipeline — from any GPX to a printed, regulation-shaped book — is live.

What you edit is what prints​

The editor shows your book as the official page: the 148 mm Diagram-1 rows with the distance, tulip and description boxes at their measured widths, the red danger frames, the green close-note boxes, the orange speed-zone frames, the comma decimals. A splitter zooms the paper without ever distorting it, because the same millimetres drive the A5, FMI and moto-roll print layouts — now led by a proper page-1 cover with the event block, the day's waypoint radii and the change log.

Behind every edit sits the same server engine that generates and bakes the TET books. The editor never re-implements a rule: change a danger level, paint a speed zone, drop a note — the book comes back renumbered, re-measured, and re-linted, with the findings panel (one DSS, !!! needs a safety waypoint, no box over 400 m…) one click away from the row it names.

Ride it at the desk​

The flow we ended up loving: open any GPX, start a blank book, and walk the route. A cursor steps along the track — or jumps straight to the next bend — and each add note drops a vignette that then populates itself from the data underneath: the generator reads the stretch around it and fills in the junction tulip, the crossing roads, the road name and surface, the exit heading, the terrain stamps. You decide; the machine does the drawing. One re-split pass afterwards inserts the regulation continue notes into whatever gaps remain.

Every piece of the vignette is hand-editable too: the tulip's arms and branches (click a handle, point it), the full 144-symbol lexicon in four abbreviation dialects, waypoints with regulation radii, CAPs, free text. Arm change tracking and your edits become versioned MODIF / NEW NOTE records, the way an opening car issues them.

The track is a first-class citizen​

Roadbooks live and die by geometry, so the editor owns the track as well as the book: snap a hand-drawn GPX onto the road network (stretches with no map data keep their shape), drag vertices where reality disagrees, and — only when you say so — re-measure the book's distances from the corrected line. By default the authored distances stay untouched: they come from the road's true arc length and are usually better than any GPX chord sum.

Keep it, carry it, hand it over​

Books save to a per-account library on the server and reopen exactly as left — track included — or travel as a single portable project file. Getting a book out is one click: OpenRally GPX for Piste, DMD2 and the rest of the reader ecosystem, or the print book for paper and roll holders.

The full walkthrough lives in the guide: the roadbook editor.
