swisstopo, from the Federal Office of Topography swisstopo, is Switzerland’s official mobile mapping application for precise geographic reference and navigation across Switzerland and Liechtenstein. It delivers national topographic maps and high-resolution aerial imagery for on-device exploration and research, with map layers spanning multiple scales and archival map material for historical comparison. Key capabilities include offline map downloads, a camera-based Panorama AR mode, and linked public-transport timetables. The app targets outdoor enthusiasts and professional users needing authoritative, privacy-conscious mapping.

What is swisstopo used for?

Built from the federal surveying programme, the app provides precise, agency-grade geodata that professionals reference for planning and documentation. It exposes map layers at cartographic scales intended for workflows where map provenance and coordinate accuracy matter, such as geological surveys or municipal planning, rather than casual consumer navigation focused on simple turn-by-turn directions.

How accurate and analysis-ready is the mapping data?

Accuracy depends on surveyed datasets and elevation models supplied in the official map stacks; the app includes recording tools that preserve track metadata for later review. Tour recording functionality produces elevation profiles and allows pace adjustment during a recorded route, enabling post-field analysis and exportable tracks that support reproducible geographic work.

What are the storage and platform requirements?

Map packages for mobile use vary widely; the developer documents size tiers for offline storage and the app runs on recent iPhone and iPad hardware, with an Android version also available. The interface does not require a user account and the design limits personal-data collection to preserve privacy during field operations. That local-first approach reduces external data dependencies during remote fieldwork.

• Installer: ~50 MB
• Base Map: ~5 GB
• Full national maps: ~18 GB

Is swisstopo appropriate for aviation and regulated workflows?

The app supplies aeronautical charts, delineated airspaces and UAS awareness zones as reference layers to inform pre-flight assessment; these datasets are presented for situational awareness rather than as regulatory clearance. It supports preparatory research by drone operators and aviators, but users remain responsible for ensuring that any operational use complies with applicable platform terms and local aviation regulations.

Best suited to professionals and committed outdoor users needing verified map provenance

swisstopo is a practical choice for professionals and committed outdoor users who require documented cartographic sources and reproducible reference material for fieldwork or research. Users should account for applicable platform terms and local regulations when using location-sensitive layers. For workflows where provenance and source traceability matter, the app represents a focused, professionally oriented mapping resource.
