A dedicated web app for editing terrain and orienteering maps runs vector drawing tools directly inside a browser tab, converting geographic base data into standard cartographic symbols. Gratic provides this workflow by coupling tile-by-tile elevation models and national mapping service vector feeds with standard orienteering symbol sets. You trace features, georeference scanned map sheets, and export files that open in OCAD without installing software or managing licences.
What cartographers should look for in a browser-based map editor
A browser-based map editor must support standard vector symbol specifications, run on any operating system without plugins, and import open spatial data. It must provide drawing pens adapted to cartographic line snapping, handle scanned map georeferencing directly in a tab, and maintain file compatibility with desktop standards like OCAD.
Terrain cartographers require precision pens that reproduce complex symbols according to strict International Orienteering Federation specifications such as ISOM and ISSprOM. General-purpose vector drawing packages fail this requirement because their lines lack specialized behaviour, including automated dashed outlines, standardized tick spacing, and regulated symbol hierarchies. A dedicated cartography tool running in a browser tab gives you access to these specialized drawing behaviours instantly. Field surveyors working across different laptops or operating systems can draft roads, contours, and vegetation boundaries without compiling code or configuring system dependencies. You sign in with your email address, receive a verification code, and begin drawing immediately.
Operating system independence is another practical requirement for sports cartographers, rogaining clubs, and event organizers. Traditional mapping programmes like OCAD and OpenOrienteering Mapper rely on local desktop installations that tie projects to specific workstations or require complex cross-platform emulation. Gratic operates uniformly on Windows, Linux, and macOS, removing machine-specific constraints from the club workflow. When survey teams switch between office desktops and portable laptops, their vector layers and custom symbols remain identical. Storing cartographic data in standard coordinates means your map geometry remains accurate across different devices and viewing resolutions.
Handling legacy cartography is equally vital when updating older event grounds. Cartographers frequently rely on historical paper sheets that require spatial alignment before new fieldwork begins. Editors with built-in georeferencing allow you to upload an image of a scanned map and pin its control points to geographic coordinates. You adjust the positioning against satellite basemaps directly inside the editing tab. This alignment enables rapid digitisation of unrecorded boulders, crags, and distinct trees without jumping between multiple GIS utilities.
How web map editors ingest terrain and vector base data
Web map editors ingest base data by querying remote elevation tiles and public survey vector endpoints across a selected bounding box. The server pipelines process the terrain contours and feature geometries, mapping them to standard symbols like roads and streams so cartographers can draft immediately without configuring external GIS databases.
Starting a new terrain map once meant finding raw digital elevation models, reprojecting shapefiles, and manually styling every line type. Modern web editors replace this multi-step configuration by publishing connections to open sources and regional survey archives. Within Gratic, you define a boundary rectangle over your terrain to fetch elevation held tile by tile. The platform queries connected national mapping service APIs to retrieve surveyed road networks, watercourses, and land-use boundaries. The vector parser converts these raw geometry feeds into orienteering symbols immediately, providing workable contours, path networks, and waterlines from the first minute.
Data transparency remains essential because open data availability changes significantly between administrative regions and national borders. When a national mapping agency restricts vector distribution, our data catalogue publishes the measured reason and licensing status openly. Mappers understand precisely which layers originate from official lidar surveys and which require ground verification. Tracing over high-resolution satellite imagery fills gaps where public vector layers remain incomplete or blocked. Combining verified elevation contours with aerial layers ensures that sprint or forest cartographers draft over reliable geometric baselines.

Full print preparation and desktop export in browser cartography tools
Browser cartography tools handle print preparation by applying strict symbol specifications, managing colour layering, and structuring vector coordinates to export cleanly into desktop formats. Cartographers can design complete map sheets in a browser tab and open the resulting files in OCAD for final competition verification or club printing.
Event organizers cannot compromise on international cartographic print specifications when preparing race materials. Orienteering maps require precise colour tables, defined overprint orders, and exact line thicknesses to maintain readability at running speed. If an online editor alters standard symbol dimensions during rendering, the printed sheet violates competitive regulations. Gratic enforces standard symbol rules directly within the vector canvas, ensuring that fences, contour intervals, and impassable cliffs retain their correct dimensions. Club mappers can adjust symbol sets or design custom point and area patterns to match local terrain variations.
Export compatibility safeguards your cartographic work within existing sports workflows. While modern editing takes place online, clubs frequently archive their files in established desktop formats or send them to commercial printing presses configured for desktop software. Gratic produces map files that open directly in OCAD, ensuring that course planners and event directors can import your work without geometry loss. Linework, point symbols, and layer hierarchies translate cleanly between environments. This direct interchange ensures that your browser-based drafting integrates with established event management software and competition workflows worldwide.
Layout tools inside the browser editor complete the production chain from raw ground data to the physical page. You orient the map sheet, set the magnetic declination, and arrange technical marginalia alongside competition titles. Because the editor manages both elevation and surface vectors, adjusting sheet margins or rotating bounding boxes happens without reprojecting data layers. You inspect the finished layout on screen and prepare it for printing without leaving the browser tab.
Frequently asked questions
How do users sign in to Gratic without a password?
Gratic uses an email sign-in code sent directly to your inbox. You enter your email address on the sign-in page, receive a verification code, and enter it to access your projects. This approach removes the need to store passwords or manage account credentials while keeping your maps accessible across any browser.
Can I georeference scanned paper maps directly in the browser?
Yes, you can upload scanned maps as image layers and georeference them against modern basemaps inside the editing tab. You place reference points on recognizable features to stretch and rotate the historical survey into true geographic coordinates. This creates an aligned reference layer for tracing features or updating older terrain.
What happens if a national mapping service restricts vector access?
Gratic publishes the operational status and specific licence terms for every national mapping service connected to the editor. If an agency blocks automated vector feeds or restricts distribution, the platform lists the measured reason clearly. Cartographers can then use tile-by-tile elevation and trace remaining terrain features over satellite imagery.
Do map files created in Gratic open in desktop software like OCAD?
Yes, Gratic generates vector files that open directly in OCAD. The symbol definitions, layer structures, and coordinate references transfer cleanly, allowing sports cartographers and course planners to move projects between the browser editor and traditional desktop tools without converting geometries.
