We deliver the bases for planning, construction and maintenance, from the point cloud of a station to the volume of a gravel pit, always with proven accuracy and in the format of your software.
Every project starts with a concrete question. Here are the most common ones, and what we deliver for them.
For upgrade and maintenance projects we capture track systems and engineering structures without contact, in the required railway reference frame such as LV95 SBB. High-precision point clouds, terrain models and true orthophotos are verified at independent check points and handed over directly to your alignment systems.
Periodic flights provide auditable proof of volumes for extraction, backfill and fill bodies on a given date. From difference models between dates we quantify the movement of material transparently and keep changes traceable over the years.
From classified LiDAR point clouds we analyse the trees along high-voltage lines and detect conflicts with the defined safety clearances automatically. This serves as a planning basis for targeted cutting back and reduces the risk of supply failures.
High-resolution camera systems document piers, load-bearing structures and soffits that are hard to reach, as well as pylons with their insulators and bolted connections, without contact. Crack patterns, traces of corrosion and material break-outs are captured below a millimetre and provided as a georeferenced basis for damage assessment.
High-resolution true orthophotos and point clouds capture cracking, rutting, deformation and markings with high precision, without obstructing traffic. The data form the objective basis for systematic asset management and for accepting completed works with evidence.
Periodic flights document the state of construction on a given date in high-resolution orthophotos, textured 3D meshes and immersive Gaussian splats. Clients, planners and contractors identify deviations from the plan early and settle the earthworks carried out transparently.
For conversion and repair projects we merge terrestrial laser scanning and drone flights into one complete, georeferenced dataset. From it we model precise, IFC-compliant BIM and CAD models for architecture, structure, interiors and the surrounding terrain.
We combine photogrammetry and LiDAR laser scanning from drones, helicopters and terrestrial systems into one homogeneous dataset. This unites the highest spectral image resolution with dense geometric coverage of demanding objects.
Every project is fitted into the Swiss national network using ground control points measured by total station or GNSS and verified at independent check points. We document the accuracies achieved statistically in a transparent test report.
As a certified operator we fly in the «specific» category of the Federal Office of Civil Aviation (FOCA). We take care of the entire permit management and coordinate operations in control zones and above critical infrastructure.
Point clouds, true orthophotos, terrain models and 3D meshes come from a single coordinated flight plan. That avoids discrepancies in time between the datasets and guarantees they fit together geometrically.
Classified point clouds from photogrammetry and LiDAR, with proof of accuracy.
Terrain and surface models for planning, volumes and natural hazards.
True-to-scale aerial images as true orthophotos, in natural colour and colour infrared.
Detailed images of bridges, pylons and roofs, without scaffolding or rope access.
Volumes, changes, clearances and vegetation, analysed from aerial images and point clouds.
As-built models of buildings and sites for conversion, renovation and operation, inside and out.
Building models of an entire municipality with roof shapes, newly created or updated.
Textured 3D meshes of buildings, neighbourhoods and entire cities.
Vegetation indices and thermal images that show what the eye cannot see.
High-resolution drone survey of Zurich Tiefenbrunnen station in the LV95 SBB reference frame as a planning basis for the 2029 track renewal.
At the Reichenau-Tamins RhB station, we merged drone imagery, airborne LiDAR and terrestrial scans into one point cloud and verified its accuracy.
As a certified operator we fly with an authorisation from the Federal Office of Civil Aviation (FOCA) in the «specific» category, based on SORA risk assessments. Every operation is agreed in advance with the client, the railway or grid operators and with Skyguide for flights in control zones. We obtain all official authorisations and operational clearances beforehand.
The accuracy that can be achieved depends on the sensor resolution, the flying height and the connection to ground control points. On demanding infrastructure projects we achieve mean deviations at independent check points of a few millimetres to less than one centimetre. We define the accuracy required for each project in advance and document the values achieved in a transparent test report.
Sovereign tasks of official cadastral surveying are reserved for licensed surveying engineers entered in the Swiss register of surveyors. We act as a specialised technology and data partner for surveying and engineering offices and deliver high-precision aerial images, LiDAR point clouds and terrain models. The data are fitted directly into the official reference frames and cadastral systems.
We hand over point clouds as LAS, LAZ or E57 and true orthophotos and elevation models as georeferenced GeoTIFF or XYZ rasters. Three-dimensional building solids are provided as CAD and BIM vectors (DWG, DXF, IFC) and as 3D meshes (OBJ, FBX, 3D Tiles). We match tiling schemes and coordinate systems exactly to your target systems, including Swiss national coordinates (LV95 with LN02) and railway reference frames such as LV95 SBB.
Yes. For engineering, geology and surveying firms we take on the survey flight and processing as a subcontractor. We deliver orthophotos, point clouds and elevation models in your coordinate system and format, so you can use the data directly in your project. The professional assessment and the responsibility towards the client remain with you, and on request we do not appear towards your client.
We are happy to advise you on the right services for your project.
