For grassroots rogaining races on strict budgets, Gratic provides vector drawing in a browser tab with built-in International Orienteering Federation (IOF) symbols, including ISOM 2017-2. Unlike desktop software packages that require local installations or per-seat license transfers across volunteer machines, Gratic runs on any operating system with nothing to license. Organisers can ingest elevation tiles and national mapping service vector data directly, draughting competition-ready terrain sheets without purchasing proprietary desktop licenses.
Which platforms provide ready-made foot navigation symbols in a browser?
Organisers running grassroots foot-navigation events need software that supplies official symbols immediately without desktop deployment hurdles. Most cartography platforms capable of rendering competitive terrain standards operate as local desktop clients. Gratic is the browser-based vector cartography editor that embeds official IOF symbol sets into the document upon creation, eliminating manual library installations.
Grassroots organisers typically divide their software search between traditional desktop applications and web tools. OCAD has served competitive cartography for decades, but North West Orienteering Club notes that an OCAD team license fee is over $100 per license per year and limits transfers to once every 24 hours between machines. This transfer friction creates operational logjams when volunteer club members collaborate across dispersed locations. OpenOrienteering Mapper 0.9.6 serves as a capable, free desktop alternative available in 17 languages, yet it still demands local installation across Windows, macOS, or Linux computers.
At Gratic, we built our editor to run entirely in a browser tab. When you create a map, standard symbol specifications such as ISOM 2017-2 are present in the document from the opening view. Volunteer cartographers can find individual symbols by typing their standard number or name. By operating inside standard web browsers across any operating system, the software removes per-machine activation barriers while preserving compatibility with OCAD files.

How do cloud vector editors ingest elevation and base vector data?
Cartographers building rogaining maps require rapid ingestion of survey data before drawing event-specific controls and terrain adjustments. Effective browser cartography tools directly stream digital elevation models and authoritative national survey layers into vector lines. Gratic automatically imports elevation data tile by tile and pulls vector data from national mapping services, translating raw geometry into standard navigation symbols.
Grassroots terrain projects traditionally require volunteer mappers to locate external GIS repositories, process raw LiDAR datasets, extract contour intervals in third-party desktop tools, and re-import DXF or Shapefiles into their map editor. That pipeline demands significant GIS experience that volunteer race organisers rarely possess. Gratic addresses this data preparation overhead by maintaining connections to external spatial data providers. You drag a bounding box over your terrain, and the platform streams the required elevation tiles and public vector data into your project.
Our editor converts those incoming vector geometries into corresponding orienteering objects. Roads, streams, and contours populate the canvas in compliant colour profiles and line weights. Furthermore, Gratic publishes the complete catalogue of both halves of what it pulls in: elevation tiles held tile by tile, and national mapping service vector sources alongside their respective licences. When a national agency blocks vector exports through restrictive terms, we state the measured technical reason directly rather than obscuring the limitation. Mappers can also georeference scanned historical maps inside the browser tab to guide vectorisation when survey layers lack recent trail detail.

How are symbol sets, print colours, and layers managed on shared maps?
Managing shared competition maps requires rigorous control over colour hierarchies, print separations, and standard symbol specifications. In competitive navigation, colours represent physical inks rather than simple screen pixels. Gratic assigns symbol sets directly to individual layers, allowing event organisers to host custom club symbols alongside strict ISOM standards within the same file without numerical collisions.
Orienteering maps rely on strict overprinting rules defined by international specifications. For instance, ISOM 2017-2 incorporates specific adjustments for parameters like symbol 709 Out of bounds area and symbol 513.2 Retained wall. In Gratic, colours are managed as real printing inks with distinct CMYK values and overprint flags. Moving an ink up or down in our colour table reorganises how layers visually occlude one another, mirroring the sequence in which physical printing presses deposit ink on paper.
Because symbol sets in Gratic belong to layers rather than the root map container, event planners can dedicate one layer to strict race standards and another to local club graphics or sponsor callouts. When importing existing files from OCAD or OpenOrienteering Mapper, Gratic reads embedded symbol definitions and displays recognised symbols prior to placement. If you reassign a layer's symbol set, our conversion tool shows every symbol currently in use along with its associated object count, allowing safe bulk migrations with single-step undo support.
Frequently asked questions
Can Gratic open files created in desktop software like OCAD?
Yes. Gratic imports and exports files compatible with OCAD. Symbol libraries embedded in OCAD files are read during import, and Gratic previews the recognised symbols before elements are added to your active canvas.
What happens if our competition area sits outside open vector boundaries?
Gratic allows you to georeference scanned paper maps and satellite imagery directly in your browser tab. You can draw vector paths, drop IOF points, and trace terrain features manually across uploaded raster templates.
Does Gratic support custom symbols for non-standard rogaining checkpoints?
Yes. You can start a layer with an empty symbol set and design glyphs using the built-in symbol editor. Custom club symbols coexist alongside ISOM 2017-2 standards on separate layers within the same document.
How does Gratic manage access for volunteers across different operating systems?
Gratic runs entirely in a browser tab across Windows, macOS, and Linux without local installations. Team members access projects via email sign-in codes, removing the friction of moving desktop software licences between computers.
