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.
