Simply clarify with us in a preliminary discussion what kind of modeling you want based on our aerial photos. By using the most modern software for evaluation and modeling, we provide you with precise and meaningful image material that fulfills your purposes 100%.

Surveying with drone - your benefits

Accurate measurement results

Thanks to state-of-the-art drone technology and the use of a high-resolution camera, you are assured of precise measurements. The precision is in the range of a few centimeters even for large measurement projects.

Easy accessibility

Our drones (UAV) reach hard-to-reach areas effortlessly and create images that would not be possible with conventional methods. There is no need to interrupt work on your construction site or in your industrial plant for the drone survey.

Effortless replication

Thanks to our GPS station and intelligent flight planning, drone measurements can be repeated exactly at a later time. This offers you great advantages for detecting defects or for target/actual comparisons.

Diverse use of data

Whether orthophoto, 3D model or digital terrain model, we are happy to process our measurement data for you using CAD, GIS and other industry-standard software. This ensures immediate further use for your purposes.

What is a drone survey?

In drone surveying, a drone or UAV is used to survey a piece of land, a building, a roof, and so on. Different sensors such as lidar, RGB cameras or multispectral cameras can be used. However, the most common method is to use drones with high-resolution RGB cameras, where the area of interest is photographed several times from different angles. The images are assigned coordinates and processed in special software to create a 2D orthophoto or a 3D photogrammetric model.

During analysis, the photos showing the point of interest from different angles are combined to create a 2D or 3D map. The photogrammetry software can use the survey drone data to create high-resolution orthomosaics, elevation models (topographic maps), or 3D models of the point of interest. These maps can then be used to produce accurate information on distances, areas, or even full volumetric calculations.

A major advantage of drones for surveying compared to manned aerial vehicles is that they fly at much lower altitudes and can therefore capture images with much higher resolution and very accurate data. Another big advantage is that these images are much more economical and faster to create.

What are the advantages of drones in surveying?

During a single drone flight, thousands of measurements are taken compared to conventional methods, creating a point cloud in a new dimension. This data can be output in various formats such as orthomosaic, point cloud, DTM (Digital Terrain Model), DSM (Digital Surface Model), contour lines or even for volume calculations.

Cost reduction through surveying with drone (UAV)

The acquisition of topographic data is many times faster than previous methods and requires fewer personnel. In mountainous or difficult-to-access areas, the risk to personnel is also reduced. For high-precision maps, additional control points are set with a GNSS reference station, which then serve as reference points on the photos.

Mapping of otherwise inaccessible areas

A survey drone can take off and fly in difficult conditions and at high altitudes thanks to modern technology. This enables the exploration and mapping of inaccessible areas in the mountains, precarious steep slopes or very rough terrain without danger to personnel.

What are drones used for in surveying?

Here are some examples of how drones are used in surveying:

Land management and development

Surveying drones greatly simplify land management and planning. Aerial photos taken with drones can quickly and accurately create data such as orthophotos, 3D photogrammetry models or topographic maps with contour lines. The resulting data is used for the construction of allotments, housing developments or roads. This drone-generated survey data also provides a detailed foundation prior to construction, as these models can be imported into any CAD software, giving engineers an instant 3D model for design.

Since this process can be repeated cost-effectively with drone imagery, the data also provides detailed information on the progress of the construction project at regular intervals.

Volume calculation with drones

With our software it is also possible to calculate exact volumes based on the 3D model. This can be useful, for example, for stockpiles of gravel pits or mines, or for the calculation of an excavation pit or a backfill, or even for natural disasters such as mudslides, a volume calculation. High-precision images and the coordinates anchored in the image or pixel are used to create point clouds with thousands of measurement points. This allows very accurate volumes to be calculated, which in turn is useful for planning or costing. For example, it is possible to calculate how many trucks are needed to deliver an excavation. Due to the short processing time of a drone survey, a snapshot can be created, which can then be used for an as-built survey.

Land surveying and cartography

The high-precision data produced by our survey drone, such as orthomosaics or 3D models, can also be used cost-effectively to create obsolete, low-quality maps or maps in areas where no data is available. As a result, cadastral maps can be created quickly, accurately, and cost-effectively in hard-to-access and complex environments. In addition, thanks to the high-resolution orthomosaics created by our survey drone, it is possible to identify street signs, curbs, hydrants and drains, manhole covers, and road markings. Based on the 3D model created by our photogrammetry software, very detailed elevation models can be created with contour lines or breaklines of buildings or properties.

Monitoring steep slopes

Through regular photogrammetric evaluations, our survey drone can also help monitor steep slopes and thus contribute to the containment or prevention of landslides or rockfalls. A major advantage is that this can be done without risk to personnel, as such surveying often involves great danger.

Using orthomosaics taken at different time periods, areas of danger can be quickly identified by overlaying these maps. In this way, changes become quickly apparent and targeted action can be taken. With this data, it is possible to quickly and accurately predict landslides and prevent damage to roads, rail lines or bridges.

Drones in urban planning

Due to the development of increasingly densely populated and complex residential areas, urban planning involves high costs and a large amount of time. Here, too, our drones can help. With our surveying drone in combination with our software and high computing power, it is possible for us to collect large amounts of data in a short time and process it into an orthomosaic or 3D model. The data obtained in this way enables planners to provide detailed information about an area in a short time. Social or environmental conditions can also be studied to test the impact of different scenarios. 3D models can also be used to easily and accurately transfer planned objects into the model, giving citizens an experimental perspective of a complex development project. In addition, 3D models can also be used to analyze and visualize shadows or vistas.
