Onx

onX is a digital mapping platform developed by onX Maps LLC that provides navigation tools and location data for outdoor recreation. The service offers mobile apps and a web portal designed to help users plan trips, locate land features, and navigate unfamiliar terrain. It is widely used by hunters, hikers, anglers, and outdoor professionals to access property boundaries, public lands, and other map layers in real time.

Core features include offline maps, downloadable map packs, and the ability to search for places, tracks, and coordinates. Map layers cover topo, aerial, and hybrid views, with some products offering 3D terrain perspectives. A key data layer displays land ownership with parcel boundaries and landowner names, alongside public land and state land boundaries. Users can mark waypoints, record tracks, plan routes, and share locations with others. Specialized products add hunting-specific data, backcountry navigation tools, or off-road routing.

onX products are available on iOS and Android devices and via a web interface. Access to most map layers and offline functionality requires a paid subscription. The company markets several product lines—onX Hunt for hunting, onX Backcountry for backcountry travel, and onX Offroad for off-road vehicle use—each with its own subscription option.

Data coverage and sources: the platform aggregates land ownership and boundary data from public land surveys and multiple private data sources. Coverage is strongest in the United States, with additional data available in other regions where partnerships and licensing allow.

Reception and use: users value offline access, convenient boundary visualization, and integrated navigation for field activities. Critics note potential inaccuracies in boundary data and emphasize verifying critical ownership information with official sources before making legal decisions.
