Horizon Mapper - Free Isochrone Maps (Professional Decision Packs Coming Soon)
Professional travel-time, population, and accessibility analysis — free core map, with professional Decision Packs coming soon.
What is Horizon Mapper?
Horizon Mapper is a professional-grade web application for generating and analyzing isochrones (travel time zones). Core map use stays free, including population and accessibility overlays. Decision Packs — coming soon — will add saved, exportable reporting for commercial, consulting, and planning decisions.
Key Features
Interactive Isochrone Generation
Create travel time zones for driving, biking, and walking with duration ranges from 5 to 60 minutes. Visualize accessibility from any location worldwide.
Custom Drawing Tools
Draw, edit, and manage custom polygon areas on the map. Perfect for defining service areas, exclusion zones, or areas of interest.
Geometry Operations
Perform advanced spatial operations including union, subtraction, and intersection of polygons to create complex analysis zones.
Real-time Analytics
Calculate area (km²) and perimeter (km) for individual zones or combined geometries with instant updates as you draw and edit.
Export Options
Export your maps as GeoJSON files (with zone metadata) or high-quality PNG images for use in presentations, reports, or GIS software.
Shareable URLs
All zones and geometries are encoded in the URL, making it easy to save your work or share maps with colleagues and stakeholders.
Free Core, Professional Outputs Coming Soon
Horizon Mapper keeps the acquisition engine generous:
- Free - Isochrone generation, population rasters, accessibility overlays, map viewing, basic share links, and basic watermarked image export
- Coming soon - Decision Pack PDF reports, no-watermark exports, saved report history, branded report pages, and advanced appendices
