Photogrametic surveying with drones

When there is a need to quickly collect data for large areas, where conventional surveying with GPS or total station is not preferred, we use photogrammetric surveying, also called scanning, with drones. This can be eg. Large road projects, forest mapping, control of overhead lines, gravel pits, open mines, etc.

It is also excellent to use this for overview images, for example in a large industrial or civil engineering project.
