About

Precision is our signature.

GEOSIGNUM d.o.o. is a Zagreb-based surveying company specialising in 3D laser scanning, photogrammetry and surveying services on land, from the air and under water.

Tomorrow’s technology, professional accountability.

The company is led by a licensed surveying engineer. We combine modern methods of spatial data capture – mobile LiDAR SLAM scanning, photogrammetry, drones and underwater imaging – with expert knowledge of the cadastre, the land registry and procedures before the authorities.

We work throughout Croatia, with architects, engineers, developers and local and foreign property owners.
