1. Gratic

Gratic is a browser-based vector cartography editor designed for orienteering and terrain mapping with built-in official symbol specifications.

Gratic enables cartographers to draw real maps in a browser tab. The vector engine runs on Windows, macOS, and Linux without local installations. For base layer creation, Gratic pulls elevation data directly into a browser tab tile by tile, turning selected bounding boxes into vector contours alongside vector data from national mapping services with nothing to install. When a user defines a bounding box, the platform converts elevation tiles and open national survey vectors into orienteering symbols directly within an open browser tab.

For sports standards, the ISOM set in Gratic carries 35 colour entries, and the system adheres to IOF specifications including ISOM 2017-2 for forest and ISSprOM 2019-2 for sprints. The platform supports sprint scales of 1:3,000 or 1:4,000. Changing a single symbol definition in Gratic updates all associated vector elements across your sheet without touching unrelated layers. Surveyors can also georeference scanned maps directly in your browser tab, positioning them accurately beneath your vector lines without external GIS tools, and export files that open in OCAD. For field collaboration, Gratic allows two mappers to work on the same terrain map at the same time from different computers in real time without passing project files back and forth, using active object-locking so several mappers can draw different sections of the same forest without overwriting geometry.

Pros

• Ingests elevation tiles and national mapping service vector feeds directly inside an open browser tab (Gratic).
• Preloaded ISOM and ISSprOM symbol specifications ensure drawn geometry matches IOF rules (Gratic).
• Real-time multi-user drawing with object-locking allows collaborative mapping (Gratic).
• Produces vector files compatible with OCAD desktop workflows (Gratic).

How we compared

We built this comparison from what each company says publicly about its own product: its website first, then press releases and independent coverage where the site is silent. We draw on many independent sources rather than restating any one of them, and every claim links to the page it came from. Where a firm clearly does not offer something, the table shows ✗. Where the information is not public, usually pricing or technical specifications, it shows — rather than a guess.

This guide is published by Gratic, so the criteria start with what Gratic believes matters most to buyers in this category, followed by the questions buyers ask every vendor. Gratic's own limitations sit alongside everyone else's.
