TRIGIS uses flying drones in combination with high-resolution measuring cameras and heat image cameras.
The drone thus closes the gap between terrestrial surveying and aircraft supported aerophotogrammetry.
Survey and detailed photographs
The bird's eye view enables large-scale overviews allowing the recognition of existing structures, documents the ACTUAL status even for inaccessible locations, and delivers fast aerial maps and orthophotos.
Services
Survey and detailed photographs (inspection, marketing, building documentation, surveying, etc.)
We evaluate acquired photographs photogrammetrically.
This requires the determination and evaluation of control points for the exact orientation of the photographs in a position and elevation reference system. Following this step, the pixels of the aerial photographs are exactly evaluated geometrically and transferred to the CAD system.
High-resolution orthophotos
Orthophotos with topography

Infrared images
Infrared images are ideally suited for the detection of hot spots on buildings, such as cold storage areas and storage depots, or for controlling solar collectors, transformers, etc.
Services
