Photorealistic 3D scenes

Gaussian Splats

Explore your project as a walkable 3D scene. Photorealistic, from every angle. Ideal for presentations, documentation and decisions based on real-world impressions.

Request a project

Explorable 3D scene as a Gaussian splat, buildings and surroundings in detail from an oblique view

Millimetre-accurate models with texture

3D Models & Meshes

Millimetre-accurate 3D models with realistic texture. Ready to use in CAD, GIS and visualisation software. Ideal for digital twins, urban planning visualisation, volume calculations and structural analyses.

Request a project

Textured 3D mesh of a Swiss city from the air, railway station, office buildings and streets with finely resolved mesh geometry

Aerial imagery without distortion

True and CIR Orthophotos

True-to-scale aerial images without perspective distortion. Every pixel precisely georeferenced. The foundation for planning, documentation and analysis.

CIR orthophoto (colour infrared), vegetation appears red

RGB CIR

Digital terrain and surface models

Elevation Models, Environmental Monitoring and Planning

Digital terrain and surface models for environmental monitoring, simulations, construction planning and volume calculations.

Request a project

Digital terrain model (DTM) of the Tamins area with elevation colours and hillshade, showing the Rhine valley, slopes and terrain edges

Millions of classified measurement points

Classified Point Clouds

Dense point clouds in which every point is assigned to a category. Ground, vegetation, buildings, bridges and more. The basis for engineering surveying, terrain and building models or detailed analyses.

Request a project

Classified point cloud from the air, vegetation green, buildings red, bridge yellow, power line and ground separated by colour

See what the eye cannot see

Multispectral and NIR Imagery

Specialised sensors also capture light outside the visible spectrum. This makes it possible to reliably detect vegetation health, soil moisture, environmental changes or defects in solar installations.

Request a project

Multispectral NDVI analysis from the air, vegetation vitality in false colours, crops, soil and woodland clearly distinguishable

Safe and efficient from the air

Inspections, Detail Imagery and Corridor Mapping

Infrastructure and structures such as roads, high-voltage lines, roofs or hard-to-reach facilities can be inspected and surveyed safely from the air, individually or along corridors. High-resolution images, point clouds and 3D models enable precise capture.
