SATPALDA offers a highly automated aerial triangulation service, which is the process of densifying and extending ground control through computational means. Our aerial triangulation process includes the following steps:

Establishing ground control points: We use client-provided ground control points to ensure the highest level of accuracy.
Performing interior orientation: This step involves determining the position and orientation of the camera at the time of photography.
Measuring and transferring all tie, check and control points: Our team manually measures and transfers all tie, check and control points appearing on all photographs.
Performing a least squares block adjustment: This step involves adjusting the coordinates of the control points and the exterior orientation parameters of the photographs to minimize the residuals between the measured and computed coordinates.
The ultimate goal of Aerial Triangulation is to refine the Exterior Orientation parameters for each image, which will help achieve the desired accuracy while generating Digital Elevation Models (DEMs). Our highly automated ...
... approach minimizes manual intervention and increases accuracy towards the higher side. Our Aerial Triangulation service is a combination of point selection, point measurement, point transfer and block adjustment in a single process. Our team of experts use the latest technologies and techniques to ensure the highest level of accuracy
