UAV imagery processed through SfM software yields ortho mosaics that can be then analyzed further. Automated image alignment makes time series analysis possible. Find out how Geomatica can be used to help you get more from imagery. From LAS point cloud interpolation, image to image alignment, vegetation assessment, stockpile measurement, and more. Geomatica also includes a python powered development platform making it the best option to extend processing capability to develop operational applications.
