Metashape software for aerial and underwater photogrammetry
Aix-Marseille University
Reference Teacher: Jafar Anbar (AMU)
Teacher(s): Jafar Anbar & Prof. Kalliopi Baika
This course offers a comprehensive digital skills-set of aerial and underwater 3D photogrammetric of submerged geological and archaeological landscapes with visual data collected through drones and UW cameras. The data treatment is in Metashape software for turning raw photos to 3D models, 2D orthomosaics and Digital Elevation Models (DEM).
PhD training in Aix-Marseille University (The PhD training platform ADUM (Accès Doctorat Unique et Mutualisé). Master, PhD students and professionals for up-skilling, re-skilling, and capacity building.
Participants will acquire the specific knowledge and skills to implement step by step the main phases of data treatment from photos alignment to 3D models, 2D orthomosaics and Digital Elevation Models (DEM) exportation.
Participants will be able to perform a series of processes for the production of 3D models, 2D orthomosaics and Digital Elevation Models (DEM) of submerged geological and archaeological site.
Based on the data quality, quantity and the time factor, the participants will be able to choose the most effective parameters to apply in order to achieve better results.
Participants will be able to visualise and demonstrate the documentation results and the analysed photogrammetric data effectively in different types of data sets. Finally, these results can be shared by the participants and can be exported for further analysis within other softwares.
This course gives the chance for the participants to perform the treatment tasks themselves, which will increase their ability of understanding the outcome of the different parameters and enrich their skills to adapt to or solve any problems that they could face during the data treatment with the supervision of the trainers.
Personal laptop for the treatment of data:
– at least Intel i5 processor or equivalent, but Intel i7 or equivalent would be much better
– a minimum of 12 GB of RAM, but as much as possible is preferred
– a good graphic adapter, preferably by Nvidia or AMD
– at least 40 GB of disk space
In-person lectures or online.
Evaluation by the completion of the course and the final visualization and sharing of the 3D photogrammetric data. Evaluation sheet from AMU (in English, French, – adapted to other languages as well) sent online.
The course begins with an introduction to @Metashape software. Participants will also learn to use the necessary functions of the software for data import, management, spatial analysis, and visualization, ensuring a thorough understanding of the photogrammetry project workflow.
What you will learn:
– how to follow a basic workflow
– how to solve most common problems with image alignment, models and textures
– how to clean, polish, simplify and export results for specific purposes
– how to present your results as images or 3D models online
The expected learning outcomes can contribute to the achievements of the following goals: Goal 14: Life below water, Goal 13: Climate Action, and Goal 4: Quality Education
For PhD students of Aix-Marseille University, they can simply apply through their personal account on ADUM (https://adum.fr/index.pl). For other PhD, master students and professionals by simply showing their interest to follow this course through contacting the following email address: info@unescochair-mca.org
Show participants the fundamental role of optical process in converting raw images into meaningful 3D models in photogrammetry. Introduce Agisoft Metashape as a powerful tool for processing and analyzing photogrammetric data. Guide participants through the Metashape interface, highlighting key features and tools.
Explain data processing workflow including importing photos, launching the photos alignment, building the points dense clouds, creating 3D meshes and 3D models, texture mapping for realistic visualization.
Advanced features will be demonstrated to the participants such as geographical coordinate system setup within Metashape for accurate georeferencing using control points in real-world coordinates which will allow participants to create 2D georeferenced orthophotos. Data export will be performed in different formats (3D models, DEMs and 2D orthomosaics)
Several sections from the user manuals of different softwares can be useful during and after the completion of the introductory digital courses.

Moreover, step by step instructions and practical recommendations will be provided in PDF format to guide the participants on how to process accurate data and create detailed georeferenced 3D models.
