GIS Support

For German Copters, aerial surveying is not just about drones. Rather, the focus is on solutions that contain all the elements for professional geo-data management. Nevertheless, the drones must also be able to be used safely over urban areas. Basically, the capturing of GEO data is about two essential technologies that can be used to generate point clouds. A laser or a camera can be used. Laser scanners can generate point clouds directly; when taking photos, point clouds are created using photogrammetry. Over the past two years, drone LiDAR has become increasingly popular in many industries, such as surveying, engineering, inspection, mining, and construction, where the technology can help increase efficiency, accuracy, and profits.

Pros of LiDAR

  • LiDAR is the way to go for absolute accuracy also because of the integrated GNSS data (direct measurement)
  • LiDAR’s light pulses penetrate the gaps between leaves and branches, reaching the ground below and improving the accuracy of measurements.
  • LiDAR is also preferable if the light conditions are inconsistent
  • LiDAR allows you to capture details that are small in diameter.

Pros of Photogrammetry

  • Photogrammetry is more easily accessible and can already be implemented using normal camera drones.
  • If the camera can be calibrated, mapping missions can be implemented quite easily and quickly.
  • The colours of the photos make it easier to recognize and assign structures that have been converted into point clouds.
  • The costs of photogrammetry solutions are lower compared to LiDAR

Choose LiDAR for:

  • Mapping hard to access, complex, and overgrown terrain
  • Capturing details on thin structures, such as power lines or roof edges
  • Projects where detail and precision are the priorities

Choose Photogrammetry for:

  • Context-rich scans that are accessible and require minimal post-processing and expertise
  • Maps and models that are easy for untrained eyes to understand
  • Datasets that need visual assessment

Security, speed, reliability and data protection

Which technology is used depends on the task:

LiDAR and photogrammetry are data capturing methods that cannot be compared with one another. The task determines which method is best suited. For complex mapping projects that involve elevation accuracy, complex structures, or partially covered terrain, LiDAR is probably the way to go. Costs and the experience of the team are important in both methods. It is also important to know how the data is processed and prepared so that it can be made available to the various users in high quality as a basis for decision-making.

We support the DSC women's volleyball
10-20-2021 The Dresden sports club was founded in 1898 and has a long tradition. The currently most successful team is the women's volleyball team. We have been supporting the team since 2002. 20 years of top sport with many great moments. We say THANK YOU and keep our fingers crossed for the 20th season "with us".

Sponsoring Ice Lions
10-10-2021 We as German Copters are not only crazy about drones and everything you can do with them, but also crazy about sports. Now we are pleased that, as a partner of the Dresdner Eislöwen, we can support the Dresden DEL2 team with our sponsorship in the current season. German Copters will present the penalties this season. If you love your sport with a lot of emotionality and fight hard for victory, you sometimes have to fight a little harder. In ice hockey, penalties are difficult to avoid. But we don't see it that strictly and want to present these punishments in a funny and entertaining way with little stories on the scoreboard. We received a lot of positive feedback on the first day of the match. We'll come up with more little stories. Just come to the game and check the scoreboard from time to time.

Construction Side Inspection
10-06-2021 There are tasks that only involve a visual inspection from the air. Of course, this task could also be done with an M300, for example, but it is easier to fly with a smaller drone. With small drones we have a lower risk, they are easier to set up and we can use our more expensive technology for other jobs. The Phantom 4 pro is particularly interesting compared to the Mavic 2 pro because the controller has an HDMI output, and the image can be transmitted to an external tablet with the help of a transmitter. That makes working with the customer a lot easier.

New Online-Shop
09-23-2021 Don't worry, we didn't switch to the fashion industry. Not only our employees, but also friends and drone fans have always asked us about our jackets and shirts. Everything is now easier because we have integrated our own shop into our website. Check it out, have fun and order when you enjoy it.
