A browser-based vector map editor for orienteering allows cartographers to draft competition-grade maps directly in a web tab using standard symbols, without installing desktop applications. Gratic runs in your browser, pulling elevation tiles and open vector data from national mapping services directly into orienteering symbols like roads and contours. It supports scanned map georeferencing and exports files that open in OCAD, requiring nothing to license.
How vector cartography operates inside a browser tab
Vector cartography inside a browser tab processes geometric coordinates and symbol definitions using web vector engines rather than compiled desktop binaries. The editor renders point, line, and area features directly onto an interactive canvas, recalculating line ticks, border casings, and colour priorities on the fly as you pan, zoom, and draft across survey areas.
Drawing accurate orienteering maps demands fine pen control that adheres to strict international standards such as ISOM and ISSprOM. In traditional setups, clubs rely on standalone packages like OCAD or OpenOrienteering Mapper installed on specific desktop machines, which introduces operating system compatibility barriers and local file management overhead. Gratic runs on any modern browser across Windows, Linux, and macOS without requiring local binaries or client installation. You sign in with your email address, enter the code that arrives in your inbox, and begin working immediately on your survey sheet without configuring database backends. Our drawing tools replicate the tactile pen behaviours cartographers expect, enabling you to place knolls, plot complex boulder fields, and trace intricate path networks with standard line weights.
Because cartography relies on strict colour tables and layering hierarchies, our browser editor manages symbol priorities automatically during layout work. When you adjust a feature or modify a symbol definition, the vector parser updates every associated feature across the entire drawing canvas simultaneously. If a fence tick orientation or track casing requires correction, updating the master symbol adjusts every corresponding vector object on the active sheet instantly. Scanned maps from legacy printings or previous club competitions can also be uploaded and georeferenced directly within the active canvas. This browser-based approach keeps the entire production cycle within a single application window, reducing setup time for technical directors and club mappers preparing terrain sprints or forest relays.
How base data ingestion and symbol conversion work online
Base data ingestion in a web editor combines server-side spatial data aggregation with client-side symbol assignment. By selecting a geographic bounding box over your terrain, the editor queries elevation tiles and national mapping service APIs, transforming raw vectors into standard orienteering line features, watercourses, and terrain contours on the screen.
Building an orienteering map historically required downloading raw shapefiles, lidar point clouds, or digital elevation models from national survey portals, followed by extensive geoprocessing inside standalone GIS suites. Gratic alters this pipeline by maintaining direct connections to external vector and elevation data providers across multiple regions. We publish both halves of what Gratic pulls in: the elevation data we hold tile by tile, and every national mapping service from which the editor imports vector data. When you drag a selection rectangle over your chosen forest or park, the system fetches the underlying terrain geometry and converts roads, water features, and contours directly into orienteering symbols. Cartographers bypass hours of manual contour tracing and layer tagging, starting their editing work directly from structured vector geometry.
| Technical Attribute | Desktop Standalone GIS Pipeline | Browser-Based Cartography Workflow |
|---|---|---|
| Software Delivery | Local desktop installation requiring specific operating system versions | Accessed directly by opening an active tab in any web browser |
| Licensing Model | Per-seat commercial workstation keys or complex open-source setups | Web access requiring nothing to license or activate |
| Data Ingestion | Manual downloading and reprojection of raw national agency files | Bounding box selection importing elevation tiles and open vector sources |
| Symbol Assignment | Manual styling, rule-set scripting, or layer mapping configurations | Automatic conversion of imported roads and streams into IOF symbols |
| Interoperability | Native proprietary extensions or generic exchange formats | Direct export to files that open smoothly in OCAD software |
Data access depends on national licensing frameworks, and our platform maintains total transparency regarding source availability. Where a national mapping service restricts vector access or imposes prohibitive terms, we document the licence status and the measured technical reason directly in our catalogue. This openness allows technical officers to verify data provenance before commencing a mapping project. By consolidating raw terrain ingestion and vector drawing into one screen, the workflow between survey planning and field verification remains compact and verifiable.
How browser drafting integrates with standard orienteering workflows
Browser-based drafting integrates into standard orienteering workflows by exporting clean files that open directly in desktop software like OCAD for course setting and prepress work. Cartographers georeference satellite images and scanned historical maps directly in the browser canvas, creating a verified spatial foundation that matches established printing specifications.
Orienteering clubs operate across diverse software environments, where competition planners, event controllers, and mapping coordinators frequently use different operating systems. Drafting in Gratic does not lock your files into an isolated format or force club members into proprietary licensing cycles. Once you finish tracing vegetation boundaries, adjusting contour intervals, and positioning point features, the editor compiles vector data into standard formats compatible with downstream event preparation. Files created in our browser editor open directly in OCAD, allowing course setters to lay out controls, design legs, and format event overprints using their existing competition software. This export pipeline maintains precise geometric relationships and symbol attributes, preventing distorted line weights or shifted coordinates.
Preparing sheets for fieldwork and print
Preparing a map for print requires strict adherence to sheet layouts, scale requirements, and standard legend blocks. Within Gratic, you lay out the map sheet, set the operational scale for forest or sprint standards, and configure the drawing frame directly in the tab. You can trace new terrain features over high-resolution satellite imagery or align imported contours with georeferenced survey sketches compiled by field checkers. The pens provide immediate visual feedback on minimum symbol dimensions, ensuring that gaps between impassable crags and marsh lines remain readable at speed. When the draft is complete, the map can be sent directly to local digital presses or commercial printers with accurate color representations, fulfilling club competition requirements efficiently.
Frequently asked questions
Do I need to buy a nothing to license to use Gratic?
No. Gratic requires nothing to license and nothing to install on your computer. You simply visit the site, enter your email address to receive an email sign-in code, and open the vector editor immediately in your browser tab without buying individual workstation seats or paying maintenance fees.
Can Gratic open and export files for use in OCAD?
Yes. Gratic produces files that open directly in OCAD. This enables sports cartographers to generate and refine vector maps online while maintaining complete interoperability with club course planners who rely on desktop software for race organisation.
What base data can the editor import automatically?
Gratic automatically imports elevation data held tile by tile and vector features sourced directly from open national mapping services. When you select a bounding box over your terrain, the platform pulls in roads, streams, and contour lines, rendering them directly in standard orienteering symbols.
How does Gratic handle areas where national mapping data is restricted?
We document and publish every national mapping service that Gratic imports data from, including their licensing terms. If a national agency blocks vector extraction or imposes restrictive conditions, we openly publish the specific measured reason and licensing limitation within our data provider catalogue.
Can I georeference scanned paper maps inside the browser?
Yes. Gratic includes built-in georeferencing tools that allow you to load scanned paper maps or historical competition sketches directly into your browser tab. You can align these rasters to real-world coordinates and trace vector features accurately over the underlying imagery.
