Drones are ideally suited for documenting changes to large construction projects, open-cast mining systems or other surfaces. Aerial photographs can be created from exactly the same angle and exactly the same position at regular time intervals with aircraft used by SPECTAIR. In this way, progress can be inspected and recorded for insurance purposes.



The observation of processes and changes to larger areas plays an important role, particularly in major construction projects. Building companies and insurance companies can reconstruct the exact location of cables, pipes, etc. using photographs from the various stages of the construction process and after completion of the project. The causes of the damage can be easily ascertained in this way.


The use of small aircraft and balloons for aerial photographs of larger areas is complex and costly. Furthermore, these can only fly over the terrain from a relatively high distance to take the aerial photographs. The creation of images at exactly the same points and at exactly the same angles with a satisfactory resolution is hardly possible.


Drones are particularly well suited for taking high-resolution aerial photographs from exactly the same position and at exactly same angle. The drones used at SPECTAIR are equipped with application-specific sensor systems and are ideal for systematically logging operations and processes. Progress can be recorded and documented with progression analyses, for example for large construction projects (progress monitoring).


The documentation, analysis and monitoring of spatial change processes is not only useful for construction projects but also for applications in the field of environmental and vegetation monitoring, in open-cast mining projects and other surface changes.



The team at SPECTAIR is experienced in the production of aerial photographs with drones. In addition, the drone pilots used are professionally trained for surveys, volume calculations, change and progress monitoring and other fields of application. The company has specialists such as geographers, engineers and geometricians, who can be deployed depending on the individual demands of each respective project.


The SPECTAIR experts take on responsibility for the project management, the technical preparation, the surveying of terrain with drones, the documentation and the data analysis. You thus obtain an all-round solution for your project. The approach is tailored to the project in each respective case. Of course, you will receive comprehensive advice from the professionals at SPECTAIR both before and during the project.
