Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 15 ottobre nell’aula Fassò (Edificio 4A), dalle 17:15 alle 18:30 CET.

PhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento.

La speaker Erika Piaser condurrà un seminario dal titolo “AQUA-LIDAR: A novel and open source semi-automatic workflow for LiDAR DSM reconstruction in aquatic scenarios”. 

Al termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento.

Sarà possibile seguire la conferenza anche online al seguente link.

Abstract

The need for high-resolution, three-dimensional water surface mapping in coastal environments is critical for accurately assessing the intricate interactions between environmental dynamics and anthropogenic activities. Traditional optical sensors struggle in providing accurate and complete digital surface models (DSMs) at the interface between terrestrial and aquatic ecosystems. Single-wavelength LiDAR, though useful for generating 3D point clouds, results in laser dropouts over water bodies, due to strong absorption of water in the near-infrared spectrum. AQUA-LIDAR is a four step semi-automatic workflow for high-resolution DSM reconstruction in aquatic environments, using unsupervised machine learning and LiDAR-derived features. The proposed workflow was evaluated over six different, real-world aquatic scenarios representing a range of challenging conditions.

Speaker’s bio

Erika holds an MSc in Environmental and Land Planning Engineering from Politecnico di Milano, in 2020. She is currently a PhD candidate in Environmental and Infrastructure Engineering (37th cycle) and has recently completed a four-year research fellowship with the Institute for Electromagnetic Sensing of the Environment, part of the National Research Council of Italy (CNR-IREA).

Her research focuses on a range of Earth Observation applications for monitoring wetlands and aquatic environments at different scales. Specifically, she is mainly working on addressing ultra-high resolution UAV radiometric and geometric distortions on aquatic vegetation.

In her free time, she enjoys watercolour painting and hiking up in the mountains with friends, always fueled by her passion for polenta.
