Mapping/GIS Services
We use drones (small unmanned helicopters and planes) for aerial surveys and mapping.

This is achieved by combining low altitude aerial photography with geometrically calibrated cameras and a technique called photogrammetry. With these pictures we create 3D digital elevation and terrain models as well as orthophoto mosaics.

First of all drones are very quick to deploy as they can even be flown with cloud cover.

The results are also better, both in resolution and accuracy, as the pictures are taken much lower than conventional aerial photography.

The individual images can be adjusted for the elevations in the terrain corrected for color differences due to changing weather conditions.

All the pictures can then be joined into a seamless orthophoto mosaic.

As the image is fully to scale it can then be imported directly in a CAD or GIS as a backdrop and used for measuring or mapping.

A picture says a thousand words: with photography we are increasingly reaching limits in terms of perspective. Now the perspective from which the picture is taken is as important as the subject itself.

Unlike planes and helicopters, where the costs quickly mount, micro drones and UAVs allow you to capture breathtaking aerial shots quickly and inexpensively.

Thanks to the GPS-Position-Hold technology, blur-free images can be achieved even in strong winds.

With data transfer to the Ground Station taking place in real time, the camera can be set optimally for the subject, to achieve the best result possible.

To ensure the best possible picture quality, we use only single-lens reflex cameras from established manufacturers.
