Aerial photogrammetry is a method of collecting data obtained by processing georeferenced images. Aerial photogrammetric recording is performed from a height of over 100 m with special high-resolution cameras mounted on a drone, which generate images with a resolution of even 1 cm per pixel. This method is suitable for detailed recording of terrain, buildings, construction sites, facade elements, monuments and other similar objects.
Mobile laser scanning with LiDAR sensors mounted on a drone is widely used in cadastral and engineering activities. This geodetic method of mass data collection, the main goal of which is the creation of a georeferenced cloud of points, enables precise processing of data that can represent various metric characteristics of objects.
By classifying point clouds:
- Digital Terrain Models (DTM)
- Digital Surface Models (DSM).
By vectorizing point clouds:
- Topographic Maps
- Large scale plans with detailed objects.
Geo Drone has several types of aerial photogrammetry cameras and masters the technology of making orthophoto mosaics, which represent one of the most economical and efficient ways of generating up-to-date topographical backgrounds.
Digital orthophoto (DOF) is a georeferenced digital image of a part of the earth's surface of certain dimensions that has the characteristics of an orthogonal projection, obtained by the process of orthorectification of aerial photogrammetric images.
DOF is a precise topographic base that has all the information registered on the image from which it is created, as well as all the measurement properties of topographic plans and maps of the appropriate level of detail. This kind of digital georeferenced display contains far more information than classic topographic plans or maps.
By classifying and vectorizing the content of point clouds obtained from LiDAR or aerial photogrammetry surveys, topographic maps and digital terrain models can be used in engineering practice as a basis for designing roads, bridges, planning power lines, and many other applications.
Geo Dron also offers these products with the aim of meeting the needs of engineers who need a quality basis for designing and planning.
