freemap.sk is a free, non-commercial OpenStreetMap-based web map application developed by Martin and the Freemap Slovakia team (a Slovak local chapter of the OpenStreetMap Foundation). It is a full-featured outdoor map portal with a detailed map for hiking, cycling, cross-country skiing and horse riding covering much of Europe (roughly 46 countries), with extra detail for Slovakia and the Czech Republic, and internationalization support.
Freemap is available directly in the browser and also works as a Progressive Web App (PWA), including offline capabilities.
Features
Map & layers
A single Outdoor base map renders marked hiking, cycling, cross-country skiing and horse-riding trails together across Europe (there are no longer separate per-activity base layers).
Other base layers: OpenStreetMap standard, Aerial/Satellite imagery (Esri worldwide; GKÚ/NLC and ČÚZK ortophoto for SK/CZ), Public transport (ÖPNV), several terrain and surface shading variants (SK, CZ), and MapLibre vector styles (OpenStreetMap Vector, Streets, Dataviz, Outdoor).
Integrated WMS layers (Slovakia): Cadastre, Tree Composition, Forest Types, Geological and Hydrochemical maps.
Overlay layers: interactive data layer, community photos, Wikipedia articles, Wikimedia Commons photos, NLC forest tracks, and parametric terrain shading.
Support for custom map layers (TMS/XYZ tiles, WMS, MapLibre styles).
High-resolution (retina) display support.
Layer shortcuts and full map state stored in the URL (easy sharing).
Route planner
Routing engines: GraphHopper (Car, Car 4WD, Motorcycle, Racing bike, Mountain bike, Walking, Hiking) and OSRM (Car, Bicycle, Walking); a "Straight line" option provides fully manual routing.
A route can contain multiple midpoints; individual midpoints can be marked "manual" for a user-drawn path segment.
Routing modes:
- GraphHopper: Ordered, Roundtrip, Isochrones
- OSRM: Ordered, Visiting places, Visiting places (roundtrip)
Premium waypoint-order optimization (GraphHopper "Ordered" with 3+ points).
Elevation profile for planned routes, plus colorize-by (elevation, steepness, heading).
"Route from/to here" directly from the map context menu.
Map interaction & tools
Drawing tools: points, lines and polygons with custom color, fill, width, dash, line cap/join, label and marker icon.
Measurement tools: distance, area, perimeter, elevation, coordinates and azimuth.
"Project point" tool (distance and azimuth from a selected point) and line simplification.
Convert planned routes or search results into drawings.
Persistent annotations saved in the URL or user account.
File import & track viewer
Import GPX, KML, KMZ, TCX and GeoJSON files by upload, drag & drop onto the map, or by URL. Multiple files are merged into one view.
Track viewer with elevation profile (total climb/descent) and colorize-by (elevation, steepness, speed, heart rate, cadence, power, temperature, time, heading).
Tracks can be saved to a personal map, refilled with elevation from the terrain model, or converted to editable drawings.
Map details
Detailed information about any clicked location:
- Nearby OpenStreetMap objects (via Overpass API)
- Reverse geocoding (via Nominatim)
- Administrative/geographic areas containing the point
- WMS GetFeatureInfo results from active WMS layers
Full object details including tags and links to OSM (element, history) and editors (JOSM, iD).
Search
Search by place name (Nominatim), Point of Interest category, or raw coordinates; also OSM elements and WMS feature info.
Results can be highlighted, used as route start/destination, or converted to drawings.
Objects (POIs)
Overlay selected POI categories on the map as interactive icons, with a configurable marker style (shape and color).
Photos & gallery
User-contributed geolocated photos, mostly in Slovakia.
Photo filtering (author, rating, season, upload/capture date, premium, panorama, tags) and marker colorizing.
360° panorama support.
Photo upload with metadata (title, description, shooting direction, capture time, tags) and a per-photo Creative Commons license (CC0, CC BY, CC BY-SA (default), CC BY-NC, CC BY-NC-SA), with an optional premium-only flag.
Rating, commenting and an author leaderboard.
Live tracking
Real-time tracking of personal or shared (watched) devices, with per-device watch tokens.
Display as points, line or line + points, with colorize-by (elevation, steepness, speed, time, heading, battery, GSM signal) and an elevation profile.
Integration with external tracker apps (e.g. OsmAnd, Locus, Traccar).
Sharing
Full map state encoded in the URL:
- Position, zoom and active layers
- Drawings
- Planned routes (including transport type and parameters)
- Imported tracks (by URL) and gallery filters/selected objects
"Copy page URL" function and "Share / Open in external app" (OpenStreetMap, Mapy.com, Google Maps, Geocaching, F4Map, Peakfinder, Mapillary, Waze, JOSM, iD and Slovak services).
Saved maps ("My maps")
Logged-in users can save complete map setups:
- Layers and map position
- Drawings and annotations
- Planned routes
- Imported tracks
- Live-tracking configuration
Saved maps can be updated, renamed, deleted, shared with co-editors, and flagged "Available offline". The saved-map ID is reflected in the URL.
Export & download
Export own features (route, POIs, photos, drawings, live tracking, imported track, highlighted feature) to GPX, GeoJSON or KML/KMZ, to a file, Google Drive, Dropbox, or Garmin Connect (route as a course).
Export the visible map area (or a drawn rectangle) as PNG, JPEG, SVG or PDF, with optional server-rendered overlays (contours, shaded relief, hiking/bicycle/ski/horse trails).
Offline map export as MBTiles or SQLiteDB (download link emailed).
Instructions to obtain maps for GPS devices (Garmin/BaseCamp, Locus, OruxMaps, BackCountry Navigator, BikeComputer, XCTrack).
Generate embeddable map code for websites.
Offline support
Progressive Web App (PWA) installation with offline use.
Offline tile caching of selected map areas.
Saved maps flagged "Available offline" are kept in the browser (IndexedDB) and refresh when the server copy is newer.
Login via Apple, Facebook, Google, OpenStreetMap (OAuth) or Garmin; multiple providers can be linked to one account.
Premium (yearly) subscription:
- Removal of the ad banner
- Access to premium photos
- Higher zoom levels on selected map layers
- High-resolution elevation data in supported countries (Slovakia, Czechia, Austria, Switzerland, Italy, Slovenia, Spain, Sweden, with more added); elsewhere a global 30 m model is used
Credit system (credits currently used for offline map export).
