UAV and LIDAR

About UAV and LIDAR

UAV photography, or laser scanning, is a fundamental part of the execution of any earthworks project, which, without accurate calculations, would be very difficult and time-consuming. UAV-mapping from the air shortens work-time and enables the creation of DSM point-clouds and geo-referenced orthomosaics. The surface model created from the point map is used efficiently, for example as a basis for the plan or volume calculations. All Ostromap’s experienced staff have engineering training and substantial experience in modelling services.

Procedure

The abbreviation UAV refers to an unmanned aerial vehicle, also known as a drone, which can fly without a pilot on board. The drone is remotely controlled by an operator from a ground station using radio communications. The flight is mainly automated, and the ground station controls the drone by using satellite location. Aerial photography may be carried out at a maximum of 150 metres without special permission in areas that have no flight restrictions. However, regulations vary from region to region. We are fully cognisant of the legislation concerning UAV, and we can, therefore, execute flights safely and according to the law.

UAV and LIDAR: Fields of application

UAV flight measurement enables the collection of terrain data faster and more economically than from the ground level. The size of area can range from a few to several hundred hectares. UAV flight measurement has many uses – the applications are almost infinite. If you have a particular idea in mind, we can definitely implement it together. The most commonly photographed objects are areas where you need to perform volume calculations, such as gravel deposits. It is also easy to conduct maintenance inspections of various difficult facilities through UAV airplanes’ photogrammetry, without compromising anyone’s health. Aerial photography can also be performed to produce point-cloud data or a map for municipal zoning, as a starting point for project planning and much more.

Products and services

After the flight, the data is compiled and calculated by a special program through which we can provide the client with the desired data or product. From the aerial photography area, an extensive point-cloud is created. Its point density can be calculated to a few centimetres of density. From the image area, we can also create a 3D surface model, for example as the basis for a plan or for volume calculations. We can produce precisely geo-referenced orthomosaics of an area that has the preferred coordinate system. This can also be used as the basis for a plan, or why not as a follow-up to a specific area according to the desired time span? We can also create digital elevation models of aerial photography that help visualise the elevation differences inside an area.

We also perform maintenance inspections of difficult and demanding industrial plants using aerial photographs. In areas with challenging access, we can use a drone to photograph high-resolution images. Based on these high-quality images, you can easily study the condition of the plant without risking anyone’s safety. Please feel free to contact us regarding your projects!We would love to help you with your coming projects!

Examples of the objects of photography:

  • Quantity estimates of piles or pits
  • Maintenance inspections of high stacks in the factory area
  • Inspection of roofing
  • Aerial photography of virgin territories for detailed planning
  • Monitoring of the surface on a landfill site
  • Aerial photography of an individual plot of land or continuous flight
  • Photography of golf courses through individual photos or video capture
  • Landscape photography of specific areas according to client’s wishes and needs
