Map editing software for adventure racing organizers must assemble varied backcountry terrain, ingest elevation contours, and output clear sheets for trekking, paddling, and cycling legs. Traditional desktop tools require local installation, per-seat licensing, or complex GIS conversion pipelines before drawing begins. At Gratic, we run a browser-based vector cartography editor that imports elevation tiles and national mapping service vector data directly, eliminating licensing overhead while maintaining full compatibility with OCAD workflows.
What tools do organizers use to assemble adventure race maps?
Adventure racing organizers generally select between specialised desktop cartography platforms, general-purpose GIS packages, and browser-based vector editors. The discipline demands broad wilderness extents rather than compact sprint parks, requiring editors that ingest regional elevation datasets, display vector layers clearly, and export standardized layouts that course setters can mark with controls.

For decades, desktop suites like OCAD have served as the core production standard for orienteering and rogaining cartography. According to OCAD technical documentation, the 32-bit software allocates up to approximately 3.5 GB of RAM, requires 100 MB of free disk space for local installation, and uses 70 MB of RAM with no map open. Desktop installations carry strict operating constraints: files reside on local drives, and software keys must be managed across separate volunteer machines. When multiple race directors collaborate on course legs across different operating systems, synchronising proprietary desktop installations creates administrative barriers.
Open-source desktop tools offer an unlicenced alternative for community mapmaking. For instance, OpenOrienteering Mapper release 0.9.6 runs on desktop systems and Android devices, giving volunteer cartographers basic tools to draw standard sport layouts. However, maintaining dependencies across mixed operating systems still requires every volunteer to download and configure software locally before reviewing course files.
Course-setting tools like Purple Pen and Condes focus on overprinting race controls and course legs on top of finished base maps. While essential for defining control descriptions and leg sequences, they do not function as full vector cartography editors. Organizers still require an underlying cartography tool to prepare the base layer, adjust terrain symbology, and generate clean background graphics.
At Gratic, we designed our editor around a different model. Because Gratic runs entirely in a browser tab with nothing to install or license, adventure racing committees can access the cartography canvas on Windows, macOS, or Linux through a simple email sign-in code. Standard symbol sets—including IOF specifications like ISOM—are built into the document, so organizers can assemble course terrain immediately without configuring desktop environments.
| Tool Category | Architecture | Base Data Acquisition | Symbol Handling | Output Compatibility |
|---|---|---|---|---|
| Proprietary Desktop Cartography | Locally installed binary requiring software activation | Manual file import of external DEMs and shapefiles | Full IOF specifications and custom symbol tables | Native format, standard vector exchange, raster prints |
| Open-Source Desktop Cartography | Downloaded installer built for target OS | Manual import of spatial files | IOF specifications and user-defined signs | Open formats, cross-compatibility with desktop suites |
| Standalone Course-Overprint Software | Lightweight desktop application | Underlying base map linked as background graphic | Sport control symbols and course overprint lines only | Overprinted graphic exports, event course files |
How does elevation and vector ingestion work for wilderness terrains?
Assembling an adventure racing map requires pulling together large boundaries of wilderness terrain from public survey data without manually redrawing every contour line. The process involves defining the bounding box, querying public elevation tiles and vector services, converting raw lines into sporting symbols, and verifying the resulting layers against georeferenced raster scans.
- Define race bounding box across target backcountry area
- Query tile-by-tile elevation sources for regional contours
- Fetch vector data from available national mapping services
- Automatically map raw features into standard cartography symbols
- Georeference scanned historic maps or aerial imagery for verification
In standard desktop GIS packages, pulling regional contours demands significant manual configuration. A cartographer must locate digital elevation models (DEMs), configure projection systems, generate contour lines at 5-metre or 10-metre intervals, and manually assign vector styling to each output. For an adventure race covering thirty or eighty kilometres of backcountry, this workflow consumes substantial preparation hours before any race-specific course design begins.
Gratic automates this pipeline directly inside the browser tab. An organizer drags a rectangle over the target forest, and the editor pulls in the elevation we hold tile by tile alongside vector data from supported national mapping services. Roads, streams, and contours arrive directly converted into standard orienteering symbols, providing a viable terrain map within minutes. When a national mapping agency's licence blocks vector imports, Gratic indicates the measured restriction rather than masking data availability.
Organizers also frequently need to incorporate existing local cartography or historic route surveys. Gratic allows users to georeference scanned maps directly in the browser window, placing raster sheets beneath the vector layers. Cartographers can trace over satellite imagery or scanned maps to add critical adventure racing features—such as single-track bike trails, portage routes, or unmapped logging roads—using vector pens that behave as cartographers expect.
How can distributed race teams collaborate without licensing bottlenecks?
Distributed adventure racing teams face coordination hurdles when base mapping files are tied to proprietary desktop seats. When volunteers cannot open or adjust race cartography on their personal computers without moving software keys, updating race boundaries or sharing trail edits across dispersed event staff slows down.
Gratic removes this bottleneck by keeping the symbol editor, colour table, and map geometry in a single browser tab. The editor runs on any operating system, so organizers on Linux, macOS, or Windows work on identical map documents without platform-specific rendering discrepancies. When drawing for an event, the custom symbol set travels directly inside the document layer rather than remaining tied to an individual cartographer’s computer.
Sport cartography relies on press colour separations rather than arbitrary screen palettes. In Gratic, map colours are defined as print inks rather than screen shades: users add an ink, set its CMYK values, enable overprinting, and position it within the print order table. Moving an ink up or down re-renders the map on screen according to that exact sequence, reflecting how an offset press applies inks to paper so that watercourses, contours, and vegetation screens overlay legibly.
Downstream compatibility remains vital because event directors export their final base maps into dedicated course-setting software. Gratic imports and exports files compatible with OCAD, while also importing files from OpenOrienteering Mapper with their symbols intact. Race organizers can import legacy project files, adjust terrain features online, and export files that open in OCAD for course designers using desktop overprinting tools.
Frequently asked questions
How does Gratic convert public spatial data into standard orienteering symbols?
When you drag a bounding box over your terrain in Gratic, the editor imports elevation data tile-by-tile and pulls vector features from supported national mapping services. It automatically translates raw road, water, and elevation geometry into standard ISOM orienteering symbols, giving you an editable vector base map inside the browser tab.
Can organizers import existing course maps created in OCAD or OpenOrienteering Mapper?
Yes. Gratic imports files from both OCAD and OpenOrienteering Mapper, displaying recognised symbols before drawing begins. The original symbol sets remain bound to their specific layers, allowing organizers to preserve legacy event graphics while drawing new course segments.
How are print colours managed for waterproof map production?
Gratic treats colours as CMYK printing inks rather than standard screen hues. Users can assign overprint attributes and reorder the ink table directly; changing an ink's position re-renders the map in that precise press sequence, ensuring race sheets match the exact physical overprint rules needed for navigation legibility.
Which types of mapping organizations fit Gratic less well?
Gratic is designed specifically for sports cartographers, rogaining and adventure racing organizers, and orienteering clubs. It is not intended for general-purpose GIS and municipal mapping departments, nor is it designed for commercial web and turn-by-turn navigation map developers.
