The coastal and underwater environments are not only vital hubs of biodiversity but also but also play an important role in the economic and cultural life of the entire world. These dynamic ecosystems face unprecedented threats from climate change, pollution, and urbanization. For these reasons, the UN Agenda 2030 for Sustainable Development calls on the entire scientific community to adopt innovative and sustainable approaches to study, monitor and safeguard our coastal and underwater environments. In this tutorial we will explore how photogrammetry emerges as a powerful tool for addressing this challenge, offering sustainable techniques to survey and monitor these important environments. Photogrammetry employs the principles of remote sensing and image analysis, presenting a sustainable alternative to conventional surveying methods. Leveraging aerial and submarine drones, photogrammetry allows to acquire intricate details of coastal landscapes without disturbing fragile ecosystems.

This Tutorial Session aims to explore the latest advancements, challenges, and applications in photogrammetry; describing the principal theoretical background and leading-edge methodologies, currently used during surveying sessions both in coastal area and underwater environment. The tutorial is based on lectures focused on selected topics that cover the entire classical photogrammetric workflow along with “learning by doing” sessions, where the participants will work with real photogrammetric dataset and will solve real issues.

The detailed content is structured as follows:

UNDERWATER PHOTOGRAMMETRY

• Theory: Image sensors and their features, lens and their features, the main phases of the photogrammetric workflow, planning of a photogrammetric survey, photogrammetry in underwater environments.
• Practice: chose the correct lens and sensor, lens calibration, plans a photogrammetric acquisition, create a 3D model using an underwater image dataset.

The target audience consists of students (both at MSc and PhD levels) and researchers involved in coastal area and underwater monitoring applications. The audience is expected to have basic knowledge of optics and photography and familiarity with CAD environments. The topics will be addressed by combining theoretical aspects (basics of photogrammetry, description of main processing algorithms, image formation in underwater environment) with practice on datasets and real case studies; in order to: show the potential of photogrammetry in surveying and monitoring coastal areas and underwater environments to beginners. The activities planned during the tutorial will be carried out using open-source software and/or commercial software of which temporary licenses will be provided. Attendees are expected to use their own laptop.

The tutorial activities will be carried out during a single session of two hours. A link will be sent to all subscribers to download the software and the datasets that will be used during the practical activities, just fifteen days before the start of the lecture. All provided data and software will be free-of-charge.

Silvio Del Pizzo is an Associate Professor at the Department of Science and Technology of the University of Naples "Parthenope" and a PArthenope Navigation Group (PANG) Laboratory member. He previously worked as Assistant Professor (RTDb) at the same University, where he obtained a PhD in Geodetic and Topographic Science at the University of Naples Parthenope in May 2013. His research activities are focused on the geomatic field and specifically his main interests are Camera sensors, Photogrammetry, Computer Vision, and Remote Sensing applied to navigation, furthermore during the last years he worked on GNSS positioning, Visual Navigation, and Measurements Integration algorithms. From August 2013 he worked as a postdoctoral researcher in several projects of the University of Naples “Parthenope” with Navigation, Positioning, and Remote Sensing as the main topics. He is the author of more than 50 publications in journals and international conferences.
