Student orienteering clubs sharing field laptops can edit competition maps directly in a browser tab using Gratic. Instead of managing workstation seats, transferring per-computer activations, or configuring local desktop compilers, mappers sign in with an email code on any operating system. We provide native ISOM symbol sets, direct vector and elevation data imports, and OCAD-compatible file exports with nothing to install and nothing to license.
Which web tools support competition cartography on shared hardware?
Browser-based vector tools let student clubs draft and maintain competition maps without local installation rights or machine licences. We built Gratic to run entirely in a standard browser tab across Windows, macOS, and Linux, giving mappers direct access to ISOM 2017-2 symbols, elevation tiles, and vector imports from national mapping services.
Shared student hardware introduces distinct constraints for sports cartography. University IT departments routinely lock down pool machines, preventing students from running administrative installers or storing persistent settings. Traditional desktop programs like OCAD require dedicated per-seat licensing, which prevents members from swapping machines freely between field surveys. Open-source desktop alternatives such as OpenOrienteering Mapper eliminate licensing costs, but they still demand local operating system installations, manual library management, and local file storage on machines that may be wiped between club sessions.
We designed Gratic to address shared access by operating entirely at my.gratic.app. Rather than entering complex passwords or machine-bound registration keys, members receive an email sign-in code to open their projects immediately. Because the editing canvas, symbol libraries, and rendering engine execute inside the browser tab, cartographers retain full drawing capability on locked university laptops, borrowed Chromebooks, or personal computers.
Cartography Software Architecture
- Local installation required
- Machine-bound software licences
- Manual symbol library linking
Browser-Based Architecture
- Runs inside standard browser tab
- Email sign-in code access
- Standard symbol sets loaded automatically
General browser mapping services process coordinate data or raster backgrounds, but sports cartography requires specific vector constraints. Competition maps adhere to the International Orienteering Federation (IOF) specifications, which define exact line gauges, gap dimensions, and symbol geometry. When student clubs prepare sprint or forest competition maps, their tooling must render these standard vector definitions directly on the sheet rather than general-purpose GIS point markers.
How do shared web editors handle base layers and symbol sets?
Modern browser editors load authoritative base data and standardised vector symbols directly into the working document upon creation. In Gratic, dragging a bounding box over the competition terrain queries integrated national mapping service vectors and elevation tiles, rendering raw geography directly into standard IOF symbology without third-party converters.
Preparing a base map traditionally consumes hours of manual GIS preprocessing. Surveyors must source digital elevation models, trace vector roads, and reproject shapefiles before drafting terrain features. Gratic pulls external spatial datasets directly into the editor. For areas covered by connected agencies, our service queries national endpoints directly: the land survey in Finland, PDOK in the Netherlands, IGN in France, and the cadastre in Cyprus. For terrain elsewhere, OpenStreetMap covers global infrastructure, paired with elevation data imported tile by tile.

Symbol handling on shared field laptops often leads to broken symbol paths or missing club fonts. Gratic eliminates external symbol file dependencies by embedding the full symbol specification inside the active map document. When you initialize a map, symbols and print inks for ISOM 2017-2 exist natively in the file. Additional standards for sprint orienteering (ISSprOM), mountain bike orienteering, and ski orienteering load automatically on demand.
Selecting a specific symbol instantly configures the appropriate pen behavior. Choosing a contour line activates smooth curves, while selecting an artificial structure or building switches to constrained angles. Cartographers can also build custom club symbols or import existing sets from legacy files. Because symbol sets belong to discrete layers, a club-specific marker layer and an official international competition layer coexist in a single document without identifier collisions.
| Technical Architecture Model | Operating Requirements | Symbol Management | Hardware Portability |
|---|---|---|---|
| Local Desktop Binaries | Administrative privileges and native OS compilation | Separate configuration files and external symbol tables | Machine-dependent local file storage |
| Web Browser Runtime | Standard browser engine with network connection | Embedded vector standards stored inside active map | Runs uniformly across Windows, macOS, and Linux |
| General Web GIS | Web browser session with general shapefile imports | Generic GIS styling without IOF orienteering rules | Standardised browser session without cartographic inks |
Can multiple students collaborate on the same competition map?
Two mappers can draft and revise features on the exact same map simultaneously using Gratic's real-time collaborative workspace. Our browser engine prevents conflicting edits by indicating active selections to collaborators, eliminating the need to pass versioned files back and forth between different members of the club mapping team.
Student clubs typically experience version-control breakdown when multiple mappers survey different sections of the same forest. On desktop tools like OCAD or OpenOrienteering Mapper, fieldworkers save distinct local files named with initials and survey dates. Merging those disconnected files back into a master copy requires meticulous manual copying, which frequently introduces misplaced control points or accidentally overwritten contours.
Gratic replaces local master files with a unified web canvas. When two surveyors work on the same terrain simultaneously from separate field laptops, edits synchronize across both screens. If one student drags a boulder or reshapes an earth bank, the surrounding geometry flags as busy, preventing the second mapper from pulling the same line in a conflicting direction. The club maintains a single, verified version of the map throughout the entire fieldwork campaign.
Print preparation remains strictly faithful to traditional press mechanics. Gratic structures map colours as CMYK printing inks rather than arbitrary RGB display values. You control the vertical overprint order in the ink table, matching physical press behavior where yellow and green interactions depend strictly on which ink covers the other. When laying out the final printed page, map windows sit directly on a sheet measured in true millimetres. Insets function as live magnification windows linked to the base terrain rather than static screenshots, ensuring that line weights, control circles, and pattern intervals scale accurately for high-visibility sprint enclosures or complex terrain details.
Once mapping concludes, student organizers can export vector files directly into OCAD format, ensuring full interoperability with course-setting packages such as Purple Pen or Condes. Alternatively, clubs can generate production-grade PDFs directly from the browser window. Because our rendering engine uses an identical drawing list for the interactive display and the final export, printed sheets reflect the browser tab layout without typographic shift or line distortion.
Frequently asked questions
How does Gratic support clubs that use older laptops with limited storage?
Because Gratic operates entirely inside a browser tab, club laptops do not need large local hard drives or high-performance graphics hardware. The editor processes vector data and elevation tiles directly through the browser without saving heavy spatial databases to the physical machine.
Can our club use custom non-standard symbols alongside official IOF specifications?
Yes. Symbol sets in Gratic belong to individual map layers rather than the global file. You can maintain a custom club symbol set on one layer and standard ISOM 2017-2 symbols on another layer in the same map document without numbering conflicts.
How do we transfer existing club maps from OCAD into Gratic?
Gratic directly imports files from OCAD and OpenOrienteering Mapper. When importing an existing map file, the browser interface presents a preview of all recognized symbols, mapping existing objects directly into editable vectors while preserving your original symbol definitions.
What happens if our competition terrain falls outside national survey API coverage?
Where dedicated national mapping service integrations are unavailable, Gratic ingests elevation tiles and OpenStreetMap spatial data globally. Cartographers can also import scanned historical paper maps or aerial imagery directly into the browser tab and georeference them against real-world coordinates.
