Freemap.eu - open-source OSM-based outdoor map & tools by the Slovak OSM community

Communities Norge (Norway)

Hello,

I’d like to briefly introduce Freemap, an OpenStreetMap-based project developed and operated by Freemap Slovakia, the Slovak local chapter of the OpenStreetMap Foundation.

The application is available at: https://www.freemap.eu

The project started more than a decade ago as a community effort to provide a high-quality outdoor map for hiking and cycling in Slovakia, built entirely on OSM data. Over time, it evolved into a full-featured web mapping application and today covers most of Europe with a consistent outdoor-focused cartographic style.

What may be interesting for the OSM community:

  • Outdoor-oriented map rendering (hiking, cycling, ski touring, etc.)

  • Strong emphasis on terrain: hillshading and contours, recently improved using newer global elevation datasets where higher-resolution local data is not available

  • High zoom detail (up to z20) with careful cartographic generalization

  • Minutely map updates, reflecting OSM changes very quickly

  • Multi-language user interface

  • OSM login support

Web tools useful for both users and mappers:

  • GPX track viewing and export

  • Route planning

  • Measurement and drawing tools

  • User-saved maps (drawings, notes, custom content)

  • Support for custom user map layers (TMS, WMS, and similar services)

  • Live tracking

  • Map exports (PDF, SVG, PNG, GeoJSON)

  • Community photo gallery built from user-contributed photographs linked to map features

All components of the project are fully open source:

  • the web application

  • server backend

  • outdoor map renderer and cartographic styles

  • and various supporting tools

Source code is publicly available at: https://github.com/FreemapSlovakia

The project is actively developed and continuously improved. Contributions and volunteering are very welcome, whether in development, map styling, testing, documentation, or community feedback.

Feedback from other local OSM communities is very welcome, especially regarding data quality, rendering, or features relevant to outdoor mapping in your region.

Best regards,
Martin
