Agisoft Metashape Tutorial Photogrammetry for drone mapping with Ground Control Points

Learn how to effectively process drone images using Agisoft Metashape in this detailed tutorial. Discover the importance of ground control points and how to utilize them to enhance the accuracy of your image processing.

Ground control points play a crucial role in achieving accurate results when creating 3D models and maps from aerial images. Follow along as we cover the steps involved in using Agisoft Metashape software to process drone images efficiently and effectively.

In this comprehensive tutorial series, we'll guide you through the process of processing drone imagery with Ground Control Points (GCPs) using the powerful Agisoft Metashape Professional software. As aerial survey professionals, mappers, and GIS specialists, the ability to accurately process and transform drone data into high-quality 3D models and orthomosaics is essential for a wide range of applications, from construction monitoring and infrastructure analysis to environmental mapping and topographic surveys.


Learn the step-by-step workflow to import your drone imagery, establish and measure GCPs, and leverage the advanced photogrammetry algorithms in Metashape Professional to generate precise, georeferenced 3D point clouds, digital surface models (DSMs), and orthomosaics. Discover best practices for camera calibration, image alignment, and quality control to ensure your final outputs meet the highest standards of accuracy and reliability.
