What is...? Aerial photogrammetry involves the use of aerial photographs to produce three-dimensional (3D) models and two-dimensional (2D) orthomosaics. The drone takes numerous high-resolution images of the area, capturing the same ground points from various perspectives. Software is then used to connect these images, forming a 3D representation. This process creates a comprehensive 3D reconstruction that includes not only height data, but also texture, shape, and color for each point on the map, enhancing the interpretation of the resulting 3D point cloud.
How we work? We utilize drones equipped with RTK Modules installed for an accurate geo-tag of the pictures for better results when creating the model. Our land surveying experience allows us to enhance accuracy even further by utilizing Trimble S-series Robotic Total Stations and Emlid GNSS Receivers in conjunction with the placement and measurement of GCP,s (Ground Control Points) and check-points.
