Drone surveying Zürich

We calculate in CHF based on effort. A single flat roof in the Glatt valley, driven by the Energy Act, is cheaper than a terraced hillside on the Gold Coast, which needs more ground control points and flight lines because of the topography – and if a site lies within the permit-required zone around Kloten, the clearance lead time at Skyguide is factored in as its own item. After a brief description we give you a transparent quote in CHF, with no hidden items. An initial consultation is non-binding.

Both are possible. For sites in the city of Zürich and the canton we come on site within our service radius, fly ourselves and deliver the finished model – flight and processing from a single source, billed in CHF. If your site is beyond the on-site radius, or you are a planning or surveying office and already have your own drone images, you upload them and we build the dimensioned 3D model from them.

Large parts of the city lie within the control zones of Kloten and Dübendorf. Within roughly 5 km of the airport a permit requirement applies – this is not an absolute ban, but flying there is allowed with clearance from Skyguide or the airfield operator. Inside the wider CTR the flight height is reduced to 150 m for drones over 0.5 kg. We check each geo-zone on the BAZL drone map and obtain the required clearance – whether a site can be flown is confirmed bindingly before the appointment.

The models are georeferenced and measurable; accuracy results from the site, flight height and method. For the flat commercial roofs in the Limmat and Glatt valleys, standard georeferencing usually suffices, while for the demanding topography of the Lake Zürich hillsides we apply a higher density of ground control points or RTK/PPK. Every dataset is manually checked for dimensional accuracy before delivery.

You receive a dimensioned 3D model, a georeferenced orthophoto and an area measurement in m². On request, additionally a point cloud (LAS/LAZ/E57), DXF/DWG, OBJ/GLB, IFC, plus volume, mass or shading analysis. Delivery is in your target software's format – PV*SOL, AutoCAD, Revit, ArchiCAD or QGIS.

Yes, especially for the large, partly shaded commercial flat roofs in the Limmat and Glatt valleys, which are under PV pressure from the Zürich Energy Act and the ewz solar drive. You receive real roof geometry, an area measurement in m² and a shading analysis as the basis for the layout in PV*SOL – the clean foundation for any robust photovoltaic plan.
