IGiG scientific seminar - Prof. Javier Estornell Cremades

19-03-2024

IGiG is pleased to invite you to a scientific seminar to be held in the IGIG library (100G) on March 21, 2024 from 9:00-10:00 a.m. The presentation, entitled "Applications of the satellite imagery and 3D point clouds in Environmental Science" will be given by Prof. Javier Estornell Cremades from Universitat Politecnica de Valencia. The speaker will personally give a presentation at our Institute as part of a several-day research visit.

Abstract:
This seminar will present applications of satellite imagery and 3D point clouds in forestry, agriculture and wetlands. In forestry, the estimation of forest variables using LiDAR technology will be described. This topic also describes tools for supervised classification of photogrammetric point clouds. In agriculture, the use of 3D point clouds obtained by different techniques, Airborne LiDAR (ALS), Terrestrial Laser Scanner (TLS), UAV-based photogrammetric point clouds and terrestrial photogrammetric point clouds, to calculate individual tree parameters is described. The advantages and disadvantages of each technique will be discussed. The final part of the seminar will focus on the use of remote sensing imagery to study wetlands by analysing water indices and thresholds. This information will be used to monitor changes in free water bodies".
